Human: Female engineer being given administrative duties I'm a female ME, graduated about 2 years ago and this is my first full time job out of school. When I first joined, I was given a lot of administrative tasks. I thought that was normal to start out doing, so I was fine with it until I started noticing that I was getting more of these duties than technical ones, especially compared to my male colleagues. I started pushing back and stopped doing the administrative duties, or I would delegate them as I started getting some experience under my belt and was no longer the new employee. Recently, we hired a female and male engineer at the same time. The female engineer is being handed the administrative duties without the male even being considered to do them. Now that I see what was happening to me, I don't want to see this be done to another girl. Is this normal? Should I speak to my boss about this?
Assistant: This happened to me too. I am younger and not white. I got assigned alot of tasks that my older white male coworkers did not have to do. We have the same job titles and were hired at the same time. Eventually I just got tired of it and didn't do it. Took on other technical tasks and said that I did not have enough time for it. Or I did it so badly that they took it away. It was kind of a combination. |

Human: Let’s say catastrophic sea level rise leaves a major city underwater, with only the upper stories of skyscrapers poking above the waves. What happens to those buildings? How long can a modern structure survive while submerged? I understand it would be virtually impossible (at least in the next few centuries) for seas to rise by the amount I’m talking about. But inspired by this model and Hollywood - what would happen if a modern skyscraper suddenly became an island? Would the foundation eventually give way, causing the whole structure to topple into the sea? Or would the beams corrode first?
Assistant: I would suggest reading "New York 2140" by Kim Stanley Robinson |

Assistant: The stability of foundations depends on the effectieve Soil pressure. (=Soil pressure - water pressure). It will be different between buildings, but some could start to sag, even fall over in storm winds. If the water is high enough you could lift te building because of the Archimedes effect if you don't let the water in the bottom floors. Those floors will become useless. |
Human: What invention was delayed due to the wrong material being used ? I was listening to a podcast about how material science is behind every single invention and how it doesn’t get enough attention Has there been any inventions that would have happened earlier if the correct material was engineered earlier? Which inventions faced obstacles at first due to material challenges ?
Assistant: Insulation and fire resistant materials got setback because of how AMAZING asbesto was .... |

Human: Got offered a low paying engineering job wondering if it's worth accepting Hey, recent college undergrad here. I've recently received a job offer from a startup in the Silicon Valley. The job pays about $50k and I'm aware that is low for my major (B.S. in Computer Engineering) and the cost of living in the Silicon Valley. The startup is very young, I think about 2 yrs old so I understand why the pay is low. I'm currently living with my family so I don't have to pay any living expenses but will probably take up some of the bills to help my parents out. I don't have any prior internships and experience so I feel this might be my only opportunity to get some experience since most of the other jobs I applied to have rejected me. This would be my first engineering job and I'm excited and nervous if I accept the job. I was wondering if accepting this job would make sense for my situation and before I accept this job what questions should I ask the HR rep in terms vacation days, raises, benefits, etc.
Assistant: If you have no other job, 50K seems okay. Even though it's in Silicon Valley, by working there you will be exposed to other companies and can more easily jump ship. Just do it and keep looking! Usually startups don't have much free cash, so they would try to give funny money (RSUs, options) to incentivize. Are you getting any equity? |

Assistant: You won’t even be able to afford to live there on that little. You should look east coast and mid west and aim for $60k-$70k. The engineering job market is fine don’t let anyone scare you |
Human: Aspiring Design/CAE engineer fearful of automation. Please help me get out of this rut. For context, I'm an undergrad majoring in ME and wish to work with composites and lightweighting. However, there is a growing fear inside of me (and growing by the day), about how automation could make design engineers redundant. Argh..I'm sorry I brought that up again. But this thought, that one day you could walk in to your workplace and be deemed unnecessary seems daunting to me. This demotivates me from doing anything productive at all, or learning anything useful for that matter. It makes me feel like I'm working up to gain a useless degree. Of course, in the grand scheme of things, automation is the way to go but that is probably out of the scope of this thread. I'd like for engineers working in the industry to maybe explain what the reality of all this is? How are design engineers adapting to all of this and what could probably hold for us in the future? Thanks so much for your time and I would greatly appreciate a candid answer from you.
Assistant: Just ask Siri or Alexa a question and you won’t be that worried about AI anymore. |

Human: Do most Engineers eventually go into Management ?
Assistant: A lot due just because so many places have a lack of mobility once you are an established engineer. But imo it isnt worth it at all. |
Human: Do most Engineers eventually go into Management ?
Assistant: Nope. There are other tracks like technical leadership (project leadership) and pure technical, especially specialization. |
Human: About to graduate with BS in Aerospace engineering and I feel like I don't know anything... did anyone feel something similar? 3 years of schooling, 2 of which was general ed and some foundation stuffs like static and dynamics. I'll be graduating in two quarters and I just don't feel like I know enough to be useful in real life setting. I've taken plenty of 'book courses' where we go through a text book and do problems on it. But none of them felt "real". And I felt like I just scratched the surface on a lot of topics but very few in depth. Controls? I did couple projects in matlab. Materials? Did a lot of book studies, and set through a series of lectures. Which was informative and interesting, but I don't have a clue where I'd start in a real life project. Aerodynamics? a lot of it was again book study. and I don't think real life situations will be a series of problem 10.2, 10.3 .... As far as more concrete skills go I know Solidwork, Matlab and Python pretty well. Have done fair amount of experimental work in labs. Got my hands on machining, LabView, and such but not an expert. I missed out of FEM stuffs due to schedule conflict, which is my big regret.\. I've done one internship, but it was much more independent (little to no guidance) than I thought, and I played with Arduino to make a automated roller for 3 months. Since I had no experience with it before I struggled pretty hard, and by the time I got a hang of it the internship ended. When I visited Boeing plant and such, I was pretty overwhelmed by how much work is being done. How much expertise the engineers have there. Of course I fully expect to have far less experience than the veterans, but I feel like I can't even contribute anything of real value. And that's scary. Because entry level engineer gets paid something like $70,000 as far as I know. And I feel like I can't produce nothing worth that much. What can I do? make a solidwork model? punch in some matlab code? write a 10 page report? I feel like I'm missing something and it's terrifying. What should I do at this point? What kind of skills can I learn in next 7 months to make me more useful? How do you deal with this sense of being overwhelmed?
Assistant: Getting an undergrad engineering degree let's employer's know that you know how to think like an engineer and have a basic understanding of engineering principles. You'll be taught (or self teach) what you need to know to do your job once you start. In a large company like Boeing, you won't be truly useful to them until you've been working for at least a year. Even then, you'll barely be earning your pay from an investment standpoint. |

Human: I graduated in May 2020 with a BSME and am still struggling to find a job-any advice on finally getting that first job? Firstly, I have barely gotten any interviews, but when I do the feedback has been positive. The companies just decide to go with a more qualified candidate. I’ll be the first to admit my resume is fairly weak since I did not intern during my 4 years of school and did not minor in anything. All I have right now is a B.S. in Mechanical and a 3.3 GPA. A degree in engineering is something to be proud of, but it definitely seems to not be enough to secure a job in the field. Do you have any advice as to maybe a masters program or certification that would help build my experience?
Assistant: Are you applying everywhere in the US? My first job was in the middle of bumfuck nowhere. |

Assistant: Network, network, network. You need to have somebody introduce you. A wingman, of sorts. Send in a resume to an online portal and you're an anonymous name on a page. Have someone walk your resume in and put in a good word for you, and you're 1000x more attractive as a candidate. |
Human: If you could build a manufacturing department from the ground up, what would you do? I have just taken a job with a startup as their manufacturing engineer and they currently have essentially no formal processes in place. If you could go back in time in your manufacturing facility, what are some things you wish had been done differently from the start? I really want to get things off in a good direction but I’m also pretty new to this, only being a few years into my career, so I’ve only had one other job to use as a baseline.
Assistant: Map out the operational flow and you'll find all the redundancies and double handling. Good reads are The Goal by eliahu goldratt and books on the Toyota way |

Human: MechE That Hates Coding, Is That A Problem? I have a bachelor's degree in mechanical engineering with an emphasis in aerospace and have been working for three years. In my current role in missile defense some coding ability is expected, even though I was clear I had very little, and when looking for new jobs in mech and aero it seems everything is asking for experience with things like Matlab, Python, C++, etc. I strongly dislike coding and programming. I have spent years trying to learn it and get used to it but I it very unintuitive, frustrating, challenging, and unfulfilling. When I've been asked to do it I usually fall short and can't succeed, and I feel that makes me look lazy and a bad employee, but honestly I just have a very difficult time doing it. Is this a problem for my future career as an engineer? Should I try to transition to a different field? If I want to stay in engineering and ideally mech and aero, what types of positions do you suggest I look for? Thanks.
Assistant: It’s a good skill to know, but you can easily find a field in ME without it. I graduated 2018 and haven’t touched a coding program sense. My job is FEA engineer |

Assistant: I’m in the same boat . I hate coding . It’s literally the worst thing engineers have to do . Yet I have an internship coming up that expects me to do some absurdly complicated coding . Not sure how I’m going 2 cope . If they need coders they should just hire a comp-sci person |
Human: Are most entry level graduate jobs like this? Hey guys. Working my first role out of university. I have a masters in mech eng. I went through a grad scheme where they rotate you through a big engineering consultancy. But turns out they aren’t rotating me anymore. I’ve been stuck on the asset management team within a systems engineering team. All I do all day is excel and Visio diagrams. I’ve been here for 9 months now and that’s all I’ve done. Going through engineering drawings, finding the asset name, and then putting it on a spreadsheet. Then making a visio diagram of said spreadsheet. I mean, I wasn’t expecting to be designing a rocket ship on day 1. But I also wasn’t really expecting this. My work placement was designing knee replacements in a research lab. I actually used my skills. It was technically challenging. This? This is rubbish. Are all entry level roles like this? Getting quite frustrated
Assistant: Companies sell these "rotational" programs as way to get a bunch of experience, but in reality they are a way for HR to get the manpower to fill out projects. Especially consulting where you charge the client by working hours. If you truly want to get a great rotation you have to make connections and force yourself into your next rotation. |

Human: What does it really mean when you see "Not For Lifting" on a chain, hoist, hook, clevis... I am an ME and have, almost, zero knowledge when it comes to lifting devices. Now, I understand that a plastic chain should not be used for lifting - obviously - but what about these steel chains that are rated at 4000 lbs that have a disclaimer stating, "Not For Lifting"? My assumption is that it is suitable, yet not rated for lifting and this is the companies way of protecting their ass by adding this disclaimer...
Assistant: Don’t lift people with it, and don’t lift over people with it. |

Assistant: It depends on the component a lot of the time. But as you said, it does come down to liability. In my experience it either means it's not designed to safely hold or lift a human (like a light duty pulley or a winch which only pulls in one direction) or it means it does not have certification often speced (like some ASME standard for rigging components). |
Human: How much will having a color streak in my hair affect my chances in getting internships? So earlier today, my friend gave me a gift card to a hair place to get my hair dyed because she knows I've really been wanting to get a purple streak in my hair for a while. Her gift is so sweet and so thoughtful, so I couldn't tell her that the reason I haven't done it is because I've always been worried about how it would affect my image when trying to get an internship or job in the engineering field. I'm a sophomore in college studying Aerospace Engineering. My dream job is one with NASA and I've been trying to get a summer internship with them. I'm concerned about how it would affect that. I would just really like some advice on how big of an issue this could potentially be. It wouldn't be anything super drastic, just kind of a deep purple streak across my bangs, or something similar. Thanks!
Assistant: NASA employee here. It will have zero effect on your chances of getting an internship. |

Human: How important are cover letters when applying for engineering jobs? I’m graduating this spring and I’m wondering if cover letters are as important in a more technical field like engineering. I know in some ways they can set you apart from other applicants but I was hoping to get some insight into if they’re more of an added bonus or a necessity.
Assistant: When I was desperate, yes. Today, with 7 years of experience, heck no. I don't even apply to jobs. Recruiters come to me. |

Human: Why would a bridge be built like this? One half is an inverted version of the other half. I'm probably not using the right terminology. https://www.flickr.com/photos/114582387@N06/31056877820/sizes/l/ On the far half you have all those steel parts above the bridge and on the near half it's basically the same set-up but upside down/under the bridge.
Assistant: A few possibilities: -needed clearance for boats on one span, too expensive to do on both -one side needed a retrofit and the new way was cheaper or better -the different ends had different abilities to support the superstructure -trains only go in one direction, so the second span will only be loaded when the first is as well -contractor read the drawings upside down |

Human: Why does it seem a large portion of windmills are not spinning? Hi, Occasionally I will drive by a windmill farm and notice several of them aren't spinning. Care to explain to a layman why? Are they that prone to breakdown and failure? Are there limitations on how much energy is to be produced at specific times? If such a question has been asked before, mods feel free to point to the URL and lock the thread. Thank you.
Assistant: A lot of the time there is no demand for the power. You can easily shut down a wind turbine but not a coal powered plant. |

Human: What makes someone worth hiring internationally? I have a few friends that by this point in their careers have moved abroad (some to Canada, a few to the EU), often quite easily because they are very accomplished software engineers with impressive resumes. I often hear "Come join us in Canada/NL/etc, it's great!", but I don't have the resume that makes an international move so easy. I have a bachelor's degree in M.E., a couple years of experience in telecom product design, no "impressive" jobs on my resume (no Tesla, Ford, NASA, etc.) and some basic Mandarin proficiency (HSK1 and slowly improving, so still a very long way from anything resembling fluency). What can I realistically work on to make myself attractive to foreign companies, if I ever did want to move abroad? Is going back to school (and/or going to grad school in the "target country" to get a foot in the door) the only/best way?
Assistant: International recruitment is more about a lack of local resources than about the quality of you as a candidate. If the local market is saturated they will never bother to get someone from overseas. Likewise, if there's no engineers going round, they will take any old shite and fly you half way across the world for the privelege. So the trick is to work out where in the world is having a boom and simultaneously a shortage of staff. |

Human: How long do you think until we have automated drafting? Seems like something someone should be working on. As an addition to some CAD software, smart software that can take a complex part and create a comprehensible engineering drawing for it. Obviously there would need to be caveats like adding machining methods, which tolerance method you'd use, defining features based on what spec you're using. But it seems like something that could be done today. At the very least it could be smart enough to add some basic dimensions (pun not intended) and then the drafter can add the more nuanced pieces. If I had more software experience I might try and write that
Assistant: Any Parametric modeling software (Solidworks, Inventor, NX...) can do auto layouts and auto dimensions for you. If you are really proactive on how you dimension and constrain your sketches while building the model the auto dimensions might be only partially useless. PMI data which lets you add tolerances and machining data right in the 3D model is kind of pushing things away from even needing a 2D drawing anyway. Or at least a full layout with dimensions and tolerancing. |

We would design and build large modular systems and after it was modeled they had some proprietary software where we could set module boundaries and it would generate all the fabrication drawings, piping isometrics, cable runs, structural drawings and details. It wasn't perfect but it saved a lot of time. |
Human: Do you think your job can be automated in the next 50 years? Im especially interested in EE and CE opinions on the matter as Im enrolled for one of them and concerned about future job prospects Iv heard lots of different things on the subject. For example a friend of mine claimed that anything not RF isnt hard and easy to automate while claiming CE is a safest bet there is. Seems like a load of hyperbole to me but who knows. What does reddit think about impact of automation on their respective fields of engineering?
Assistant: Automation engineer... Seems unlikely. |

Human: Has anyone worked with close friends? I work at a very small consulting company. I introduced the owner of the company to one of my close friends (a fellow engineer, I've known since college. He was initially a roommate and became a very close friend). The friend is currently on the job hunt, having told my boss this, he was impressed by friend's technical knowledge and is considering offering my friend a job. If my friend joined up, we would work largely on different projects, but collaborate together on occasion. The friend and I have concerns that working together would strain the friendship. Being engineers we are stubborn, while respecting one another's talents and skills. Has anyone worked with a close friend? How has it ended?
Assistant: > The friend and I have concerns that working together would strain the friendship Why do you think so? Especially if you'd only be collaborating on occasion? |

Assistant: Yeah, had multiple college friends including my best friend who was my college housemate work in the same department at my first company. Three of us (best friend and another college friend) shared a rental house for four years until we started splitting off doing different things. It works fine. Try to avoid working on the same projects when possible, and when you are on the same stuff just be mindful. It can work fine, even great. |
Human: Elon Musk is talking about "solarizing" Puerto Rico. What could be the problems of a large-scale solar power grid? I say "power grid" but there doesn't need to be one (I suppose that in this case solar is attractive because it doesn't need a grid so you are spared the cost of rebuilding it). If you have hundreds of independent solar-powered clusters, what problems could eventually arise, say like ground loops or phase differences? (Article that prompted my question).
Assistant: I believe a big issue is building an entire solar grid in a year with grant money and then having to replace it all simultaneously in 25-30 years when the life of the panels is up but without any grant money. |

Assistant: Biggest problem is meeting the 4878 MW of installed power plants already. At ~300W per panel all of Puerto Rico would need 16.3 million solar panels, at $200 per panel a net investment of 3.3 billion dollars, plus the sunk cost of the existing plants. |
Human: I know you can back drive linear actuators when there is no power but can you “forward drive” it too in the same way?
Assistant: Back drive just means ‘move the motor with the output’ it doesn’t imply a direction. If an actuator can be backdriven it can be moved in both directions. |
Human: I know you can back drive linear actuators when there is no power but can you “forward drive” it too in the same way?
Assistant: It really depends on what kind of linear actuator you're talking about. Some linear actuators driven by motors cannot realistically be back driven without power. |
Human: If you where to pick, what one would you choose to be the best engineering to specialize that uses your hands the most?
Assistant: Bachelors degree in Mechanical Engineering, then find a job at a small to medium sized automation company. Working at smaller companies can get you more hands on work in general due to smaller headcounts and less specialization. |
Human: If you where to pick, what one would you choose to be the best engineering to specialize that uses your hands the most?
Assistant: This is 100% dependent on your career path. |
Human: How long did you stay at your first job? I've been out of school and working for about 3 months and I don't see myself staying with this company for very long for a few reasons. I'm not sure I like my role within the company and I'm not really enjoying what I'm doing, and I don't want to be materialistic, but the pay isn't great. How long did you stay at your first job before moving on, if ever?
Assistant: Couple of years. Scoot if it's not for you and your have something better lined up. Just avoid burning bridges and omit this one on your resume. If anyone ever asks about it, say you were young and dumb and took a job without really researching it. Lesson learned. |

Assistant: 8 months as a "contracted intern", they refused to give me a full time position despite that I was clearly operating above the level of an intern. I left at the first opportunity to have a full time benefits position. Been there for almost 5 years now. |
Human: Fellow engineers, what are you best personal projects? Whether it's something like a simple DIY test equipment or a full functioning robot, any personal project you are proud of relating to your field.
Assistant: I'm an aerospace engineer, but I tend to gravitate towards outdoor work instead of field related. I've added a garden, some landscaping, and have done a lot of work on my deck for fun. The garden was the most enjoyable. I guess the closest hobby I have that is related to my field is using a smoker. I like to think about the fluid dynamics behind the air flow. Edit: It has the added benefit of creating tasty meat. |

Assistant: I volunteered on my son's First Robotics team this past winter. They were a rookie team, just me and the teacher, and maybe five kids. And we won at one of our events and went to the district playoffs. Any engineers here with kids in highschool/about to go into high school, I really recommend you get involved in First Robotics. It was a great experience I got to share with my son. |
Human: How the pandemic has led to changes in communication at your workplace? I'll start first. More meetings. We only had one board room and maybe one empty office so people really limited their meetings. Now it's whenever people feel like, before/after business hours, during lunch, triple booking, several hour long meetings. I can hardly find a time where I can 100% focus on completing my experiments. How's your experience?
Assistant: We "worked from home". AKA no one actually did any useful work. Meetings moved from conference rooms to WebEx. Which was terrible enough on its own. But then our wonderful "IT department" decided to really shit on our faces by replacing WebEx with this utter shitshow Microsoft calls "Teams" shortly after. Overall, "communication" went from bad to worse. |

Human: Anyone with experience working for Engineers without Borders? I'm in my 30's returning to school and am studying environmental engineering. I'm interested in Engineers without Borders for the chance to help out communities and travel. I was wondering if anyone here has had experience working for them and what you think?
Assistant: I went to a meeting. There were a few students and like 3 graduates. It seemed it's more for mechanical or environmental engineers. They talked about doing water transportation stuff and home building which is cool and all, but I'm computer engineering. Not much for an EE or CE or CS major in my opinion. |

Human: Engineers who did a master's then went back for a PhD, did the master's accelerate the PhD? Both if you went back to the same school or a different one. I.e. if PhD would normally take 5 years, and you did a master's, would that then make the PhD take approx. 3 years?
Assistant: Ha. I did my masters and my advisor offered for me to stay on for a PhD. I completed my masters in two years I thought initially 3 more year is doable and then he said 5-6 years and I laughed and left for industry. Newp. |

Human: Does anybody have access to (or source for) a small piece of Cobalt chromium Molybdenum alloy for a project Hey all, I realize this is unconventional but have hit some dead ends. My girlfriend is undergoing a major surgery and getting an implant consistenting of UHMW, co-cr-mo, and titanium screws. I've got sources of UHMW both as solid and dyneema, and titanium is easy to get... Does anybody have a small scrap or know where to get a small piece of Co-cr-mo? I want to make her a pendant necklace or desk thingy using all her new "cyborg" materials.
Assistant: You might be able to get an actual one of these implants that was rejected during manufacturing for some quality control issue (a flaw from machining or the like). I know someone who got a bunch of quality-control-reject implants donated for use in a display on bio-compatible materials. Try contacting the company that makes the implants, or another implant supplier. |

Human: What implications do new technologies like 3D printing have for physical security and professions like locksmithing? I just learned my employer holds a patent on the keyway we use in my facility. Obviously this has great advantages for physical security. Does 3D printing currently threaten this, i.e. is it possible yet to scan and recreate a proprietary key within the correct tolerance, or will it likely be in the near future?
Assistant: It doesn't make much of a difference. If you have access to the key to scan it, you can reverse engineer it in any number of ways and a copy could be made any number of ways as well. If a criminal is going to the trouble of copying a key rather than brute forcing their way through the lock, there were like 20 ways to do it before 3D printing. |

Human: What was it like getting your master's degree while working? I'm considering a part time professional master's degree program. My company will pay for it, and it is a valuable degree. But I know it's gonna suck working full time while taking a class or two every semester for 4 years. Anyone who has done this: how much did it suck? How much did it help your career? What did you have to sacrifice, and would you do it again?
Assistant: >how much did it suck? For moments it sucked a lot since occassionally I would get extremely busy. Especially when a project or paper was due. >How much did it help your career? Allowed me to change industries at a higher pay. >What did you have to sacrifice, and would you do it again? Time and health. Maybe. |

Human: Science fiction is full of walking tanks, but would there be any advantages of legs over wheels/tracks?
Assistant: For their size they can handle rougher terrain. I think this is one of the motivating factors behind the development of Boston Dynamic's Big Dog. However I think when you get to the size of a tank then the need to get over relatively larger obstacles is much lower. |

Human: Is Aviation Fuel usable in residential power equipment? Regular automotive gasoline contains ethanol, which attracts water and can cause corrosion, and limits the life of the fuel in the equipment. Non-ethanol fuel is only available near me at airports, so I was wondering if I could use any forms of that in my power equipment? (small-engine ICE, in a snow blower, lawn mower, leaf blower, etc.) I wouldn't want to use leaded variants (AVGAS 100 or 100LL) but 100UL and JET A1 (kerosene) are available and don't have lead. TIA!
Assistant: Do you live near boating? Any boat is going to run 91 which is ethanol free |

Human: Can anyone offer some advice in changing my career path as an Application Engineer in the Water/Wastewater Industry? I work as an Application Engineer for a pump company that mostly specializes in the wastewater industry. We also do a lot of work with treatment plants and potable water booster systems as well. I am trying to figure out my next career move as I feel like it is time for a change and there is no room for further advancement in the company I work for. I have worked for this company for about 5 years now and was hired right out of college after completing my Civil and Environmental Engineering Degree. I have thought about changing fields, but haven't decided anything concrete. I work on electronics projects as a hobby and one of my favorite aspects about my current job is the electrical aspect of working with control panels, VFDs, motors, etc, so maybe something in the electrical field may not be out of the question. On the other hand the water industry seems like a good industry to be in right now as engineers in this field seem to be in high demand. I feel like I may have forgotten about 80% of the things I learned in college since graduating which I feel might be a problem going forward. I am not sure what I need to do to prepare before I start searching for another job. About the only thing I know for sure is that I want to move far from where I live right now (South Florida), ideally somewhere near the Pacific Northwest. Even if I don't change industry I do not want to look for another job as an Application Engineer. I would rather look for a position where I could do more design type engineering rather than application engineering. Since my only professional experience is working as an Application Engineer am I pretty much going to be stuck in this role? Any advice on how I can break out of that role? Is there anything I should do before I start my job search and start sending out resumes? What other suggestions do you have for someone in my position? Also, for what it's worth, I passed the FE Exam in Florida in the Fall of 2012.
Assistant: The easiest way I've found to change locations without transferring inside a company is to build a network at the location you want to move to so your network can help you find a job. Do this by attending conferences and career fairs in the area you want to move to. |

Human: Does anyone else feel the "Tech Culture" isn't serious? I live around the NY area working as a engineer (6 years into my career). Every so often when I feel as though my talents are going to waste, I browse the internet looking for tech jobs in the city. I'd like to go work for one of these startups, but I always get the feeling that they're more fluff than anything. It doesn't seem like the start up companies are really doing anything breakthough. It just looks like they're making toys. Where are the people pushing the state-of-the-art, creating new ways feed populations, working to clean up pollution, develop space travel, creating new energy sources. It's more like: hey look at our new restaurant app! Look at our 555 timers blinking LEDs! Raspberry Pi! Print your own wrench out of plastic! Gimmicky... I suppose its a way to make money, but it doesn't feel serious enough for me. Do I have it all wrong?
Assistant: In my somewhat limited experience, the NY area is not a hotbed of technology entrepreneurship. A hotbed of culture and art, yes. |

Human: Career progression: getting a PhD vs going into industry at entry level What's the career progression like for working at large established companies when you're starting at entry level? I've heard a few people say that they are going to get their PhD because you can either do that or work for company for \~10ish years to get to the same place (or sometimes there's just glass ceilings put in place). I'm interested in wearables which is maybe sort of niche (I only really know that the big tech companies hire for it, and most require at least a Masters). I have a job offer for an entry level position in wearable instrumentation (it looks like mainly just debugging hardware): when I think about what I want to do long term it's more than just debugging hardware (I'd be more interested in the design/conception more so than just troubleshooting what already exists). I know usually you can either advance up management or try and stay on the technical side, but how does that actually work, and if you did take a entry level role somewhat adjacent to what you actually wanted to do, how did that end up for you and where are you now? If I'm interested in staying more so on the technical side, more so on the design specifically (or making my own stuff), does a PhD make more sense than just entering entry level and working my way through? I'm just not sure what the endpoints are for either career path (PhD vs nonPhD) if I know I want to work in industry, maybe my own company. People who didn't get a PhD, what stuff are you working on now compared to what you originally intended and do you wish you had gotten a PhD, and for people who did get a PhD and go into industry, same question but flipped. My friends will frequently bring up "oh while you're getting your PhD I'll have earned XYZ amount while you're that far behind" which is true, but I'm not looking to get a PhD for the money, but rather so I can work on the problems that I want (at my school almost all the engineers just go into consulting, which is fine, but not really what I'm looking to do). My own background: I'm a senior mechanical engineer looking at going to graduate school for electrical engineering. I have a few interviews I'm in the process for right now, but I've already been accepted to a few graduate schools (tuition paid, with a small but livable stipend). I'm most interested in VR/AR/wearables/haptics, more so towards the hardware side than just the CS side, so I'm trying to figure out if an advanced degree is really worth it / required. Big caveat being I don't know that much about any of those topics at this moment, as I haven't had any classes or projects specifically in those areas. Coming from mechanical I frequently hear that at places like Lockheed/Raytheon, the PhDs design everything and everyone else does the fabrication / failure analysis / GD&T / etc. which I don't know how true that is or if it generalizes to other fields.
Assistant: In civil engineering, a PhD has little value in the industry. Maybe in structural engineering, if anywhere. Otherwise, I think that time would be better spent in the industry. Iirc, my first employer told me my masters degree gave me an extra $2000 per year. Not necessarily the best investment strictly in monetary terms. |

Human: Systems Engineers, what is the best way to become proficient with Doors? For an upcoming project I will likely be tasked with using Doors to track requirements, etc. I have a few coworkers that have used the tool in the past, but no one that is a subject matter expert. Can any one with experience recommend any books, online training, in person training, etc?
Assistant: If you don't already know the answer to "Why Doors", or more generally "Why do we need this," you should read ISO 29148. It is about processes and information used for requirements engineering. It's definitely helped me figure out how to understand requirements better and explain what requirements should be to others. |

Human: Any hiring managers on here? Curious as to what you all look for So I'm in the market for an engineering job in the US and I'm curious what hiring managers look for. My degree was in Biological Engineering which is kind of a jack-of-all-trades (perhaps more aptly put, jester-of-all-days) degree and am not having success in pulling jobs. At this point, I'd work in anything, but in case I need to go back and add to my resume, what types of things do you all look for? Is it a graduate degree that makes the difference? Certifications (LEED, EIT, PE)? General work experience? Likeability? What makes more impact? Thanks for your time!
Assistant: I look for success, accomplishments, achievements, experience Not just a list of software and courses S.T.A.R. is your friend. https://www.indeed.com/career-advice/resumes-cover-letters/star-method-resume https://www.zipjob.com/blog/star-method-resume/ https://www.careereducation.columbia.edu/resources/resumes-impact-creating-strong-bullet-points |
Human: Any hiring managers on here? Curious as to what you all look for So I'm in the market for an engineering job in the US and I'm curious what hiring managers look for. My degree was in Biological Engineering which is kind of a jack-of-all-trades (perhaps more aptly put, jester-of-all-days) degree and am not having success in pulling jobs. At this point, I'd work in anything, but in case I need to go back and add to my resume, what types of things do you all look for? Is it a graduate degree that makes the difference? Certifications (LEED, EIT, PE)? General work experience? Likeability? What makes more impact? Thanks for your time!
Assistant: Hiring manager here, run entire engineering team for a manufacturing site. Send me your resume and I can take a look and give some feedback. A biological engineer is very specific, but I saw you list some courses that could be more broadly applied… |
Human: What kind of engineer specialized in water well drilling engineering? Mechanical, Electrical, Petroleum, or Chemical? Thanks.
Assistant: Different names depending on your jurisdiction but typically hydrogeologist or geotechnical engineer. Drilling a well for drinking drinking will be done by most drilling/geotechnical outfits but please consult local health authorities on testing water for chemicals of concern such as E. Coli prior to hooking it up |
Human: What kind of engineer specialized in water well drilling engineering? Mechanical, Electrical, Petroleum, or Chemical? Thanks.
Assistant: I think a professional geologist (PG) also fits the bill. |
Human: What would happen if you plugged a gun barrel with a steel rod and fired it?. Assuming the rod is fixed at one end. What would happen if I stuck a metal rod down the barrel of say a 9mm pistol and possibly touch the bullet with it?. Would the gun just explode? Or would the gasses from the explosion just escape?
Assistant: https://youtu.be/xmt5QB814Tw I have just the right video for you. These guys are trying to blow up a cheap Hi Point 9mm pistol. They hammer a bolt down the bore around 3 minutes in. I’m guessing it results in the way it did because Hi Points don’t have a locked breech but I’d also guess a lower pressure 9mm doesn’t have the power to rupture a barrel like a rifle would. |

Human: How would you measure the mass of a plane without using any type of scales? Was looking through some brainteaser interview questions and found this. How would you approach this question? I figured we could see how much volume of water the plane displaces but the plane is made of so many different types of materials with different densities. Sort the parts of the plane that are similar and find water displaced individually? What if the interviewer asks how to find the density of the parts of the plane? We can't use a scale.. Another response: Find the model of the plane and call the manufacturer to get the specs which has the mass? That's all I could think of haha.
Assistant: Apply a known force and measure the acceleration. |

Human: How to know when to quit your job I'm a newly graduated mechanical engineer. I feel bad, this is my first job out of college, and I've only worked here for about 2 months. Due to circumstances at work, I feel like I am already on the verge of leaving. To give some back story, I work at a small company with two other engineers. They both have said they are leaving in the next 3 months due to bad experiences with the company. I know that I am not ready to be the only engineer at this company since I had no experience before this. The reason the other engineers are leaving is because management interferes with designs excessively. Ex. I almost finished my first project, but they had design ideas and wanted me to change it multiple times. Another random thing is that I found out this company has been in trouble for messing with employee wages multiple times. They also refuse to listen to the other engineers reccomendations as they want to save money in the short term at the expense of customers. I'm worried if I leave now that I'll have trouble getting another engineering job since I have this short stint here. Should I stay like a year or leave when they do? I can give more details if anyone has any questions, sorry for the long post. Tldr: worried about getting a new job when I had a bad first 6 months at this one.
Assistant: No one will care. My first job was six months. Some advice - if you're thinking daily or often "should I quit" or "should we break up" and you're having to talk yourself out of it... You should do it. |

Human: Can a compost pile's heat be used to drive airflow in an underground city? I'm designing an underground tenement neighborhood for my D&D game\* and I was also figuring out waste disposal and had a thought. Compost/midden piles generate heat from the rot of organic waste, right? And a fire can be used to ventilate a space, as its heat drives warm air up, and air flows in. Can a compost pile get hot enough, without being on fire, to draw enough air to ventilate a large underground area? Not sure if this is the right place or community, apologies if it's not. \*Yes, I know, it's fantasy, it can be whatever I want. However, I like to start from reality before I add the magic, and that requires research and sometimes asking annoying questions.
Assistant: Good luck getting that pile permitted. NIMBY. |

Human: What are your favorite cheat sheets/reference cards, etc? My boss is always talking about the old days where suppliers always sent out cool quick reference cards and funky slide rule type gadgets. If you could please post your favorites here I would love to see them. If you still get them I'd love to know who still gives them out.
Assistant: I'm partial to this one, personally. Also, in my wall of shame at work is a list of fillet radii to make non-sheetmetal parts on solidworks look like bent sheet metal, because I was forced to modify some *really* shitty imported CAD models that wouldn't convert right. I hate that I ever had to use that. Jokes and horror aside, Digikey has some pretty cool rulers. |

Human: Would a human-powered pneumatic tube package delivery system be possible? I write fantasy, and I'm worldbuilding a society that is urban, but before steam, hydro, or electricity. Would it be possible for them to build a functioning pneumatic tube delivery system for payloads similar to the ones used by hospitals/post offices? Maybe handcranked, or pedal-powered? Or would mechanisms to create the pressure required to move along the payloads and the requirements for airtight tubes be too difficult for a society like that?

Human: Being that human blood is (supposedly) substantially cheaper than printer ink on a per-volume basis, how hard would it be to make a printer that uses blood to print? I don't know if I should ask this here, on /r/askscience, or /r/morbidquestions, or elsewhere, so I'm sorry if this is the wrong place for this kind of out-there hypothetical. Basically, it is an often-cited statistic that human blood (at 1500 USD per gallon) is cheaper than black printer ink (at 2700 USD per gallon), which naturally leads to jokes about using blood in place of printer ink. Regardless if the veracity of said statistic, I'm asking if it would be at all practical, or possible, to make a printer that uses Human blood as the "ink". Also, if I decided to use, say, chicken blood (any animal blood is probably much cheaper), would it require a substantially different design?
Assistant: Of course the real question is "why is printer ink so expensive?" and the answer is that it isn't. It's a few pennies a litre for generic stuff. The unicorn spunk pricing is all about gouging. Similarly, the engineering in a printer is way over the purchase price, they're full of really cool components, motors, etc., and are beautifully built. |

Human: As an entry-level engineer, is it wise to hop from company to company every 2-3 years? I've seen several comments on multiple threads suggesting to move around and not be static within a company when becoming an entry-level engineer straight out of college. For the most part, the consensus has been about 2-3 years of work and then looking for a new company before settling. Can anyone provide reasoning as to why this is a good or bad idea from personal experience?
Assistant: You should have as much loyalty to your employer as they have to you. You should be getting regular external training (at least once a quarter) in some developing segment of your industry like a software tool or whatever. You should never have to beg to spend money on things that improve the business. And most of all you would be averaging a 5% raise per year your entire career. If you're not then go elsewhere. Employers just have no incentive to pay existing employers more. |

Assistant: 4 companies in 4 years. One company was sold, one went out of business, one just absolutely terrible to work for. I can tell you that the older hiring managers definitely frown upon the early career moves, but sometimes life doesn't give you a choice. You do what you gotta do. Bigger, more modern technology companies don't seem to care. I think it's a generational thing. |
Human: Engineers of Reddit, what co-workers do you hold in high esteem, and why?
Assistant: We have a Principle Engineer who did not grow up in the US. He actually was a University Professor where he came from. When he immigrated to the US he took a job as a field technician while learning English and worked his way up to Principle. His humility is absolutely amazing in that he gladly accepted a low level position to get started but also in that he never asks anyone to do he is not willing to do himself. He is my Engineering Hero. |

Human: How much math do you use on a daily bases? I read someone's post about hardly using most of the calculations you learn in college. How much did you use on a daily bases? I'm asking because I hear the age old saying I'll never use this math in real life, which is true for a lot of people. Obviously engineering uses math, but I'm wondering how much and for what job that you do?

Anything more complex than that I use Python with Scipy (basically MATLAB, but free). Mostly work on GA aircraft and rotorcraft. Fastener & material strength calcs all done by hand. We're a small shop (< 5 people), larger outfits like Boeing probably use a combination of FEA, Excel + VBA, proprietary software, and actual testing to confirm results. |
Human: Using a combination of simple objects buy-able at a local hardware store (ie: Lowes) how could somebody build a scale that can accurately measure tenth-milligram differences between significantly more massive objects (around 20g-50g) Please optimize between total dollar cost and simplicity to assemble. I'm thinking in order to get accurate measurements you'd need to subtract out the weight that both objects likely have in common. object 1 ( 30.1298 g ) and object 2 (30.1334 g) measuring normally to 3 sig. fig. would leave you with an inconclusive reading > 30.1 and 30.1 but if you counterbalanced off 30.1g the measurements could be more accurate at only 3 sig. fig. > 0.0298 g and 0.0334 g granted that's just from my knowledge of how the math behind significant figures works. I wouldn't actually know what I'd need to do to get that effect. Incoming help appreciated!
Assistant: You're basically asking for accuracy of approximately 1 part in 500,000 (0.0001g out of 50g), and basically equivalent to a good laboratory scale like this one. You're not going to get there in a DIY setting (at least, not without several rounds of building the tools to build the tools to build the tools) |

Assistant: I would consider using a manometer with opposed fluid columns rather than a mechanically balanced system. The error in a mechanical scale logically come from friction in the works. A fluid column is not frictionless, but the friction can be more easily computed. |
Human: A few questions on selecting a motor and battery, and on whether or not to use capacitors for regenerative breaking. Hello fellow engineers, I am trying to design and build an electric drive system for a scooter/moped. I figure it will be easier to convert an existing scoot/moped to run on batteries and electric motor, although I would like to make a custom frame eventually but that is another topic. I need help with the electrical design at the moment. First, I need advice on selecting a motor. DC seems most reasonable as the scoot will be battery powered and converting to AC is adding complexity. I think a 1 HP DC motor ought to be enough power for 350-400lbs to get up to 30 mph. Example specs for a motor I found online are: 90V DC, 36.0 in lbs of torque, and 1750 rpm. Would this be enough power/torque for this application? What kind of motor driver would I use to power the motor? is PWM suitable for this application? if 90V DC is the rated voltage of the motor, how should I step up the voltage if it is all DC? should I stack the batteries voltage in series or keep in parallel and use a buck/boost converter? That brings me to battery selection. is a bunch of 12V lead acid batteries the most reasonable for this? or one large 12V lead acid? h li-ion, ni-cad and ni-mh seem unreasonable for this application due to their cost and availability in specific sizes. My next consideration is that whatever motor I select, back-emf from the motor will have to be dissipated as heat or put back into the battery. This is where I was considering using capacitors to help offset the sudden load on the battery/ help offset the energy requirements on starting up from stop. Are supercapacitors suitable for this application? and are they relatively commercially available? how would I go about sizing the capacitor? That is all the questions I have for now. I have some background in electrical and mechanical but I am not familiar with this type of power system. Thanks for any suggestions, all help is appreciated!

Human: I spilled water onto the electrical outlet behind my desk My desk is right in front of the wall and there are sockets between the desk and the wall. I accidentally spilled around a glass of water onto the electrical outlet from the small space between the desk and the wall. At the moment, it's past 1am in my country, and although there's no visible issue so far, I am afraid that the entire house might burn down. After a research on the Internet, I dried the sockets down by a hair dryer (which was plugged into a different socket) and cleaned some of the excess water with napkins. At the moment, everything works fine, there isn't a weird smell. Should I be worried?
Assistant: If you are actually worried about any live power problem your first step should be to turn off the power at the breaker. At that point you can take the whole thing apart if you want and not get hurt. Wiping up the water from outside a live outlet probably isn't going to hurt you like others have said, but you might as well isolate the outlet before you touch it at all |

Human: Has anybody relocated from the US to Europe recently? Was it worth it? I'll be finishing my Ph.D. soon in Mat Sci&Eng in the US working on semiconductors. Mostly for lasers and LEDs. I'm looking at jobs all over and keeping my options open, but specifically the bay area has a ton of potential opportunities (obviously) and there are a few companies in Europe I'd seriously consider, specifically Austria and Germany. I've looked a bit into moving abroad, and it seems like I'd be taking a decent pay cut. Sure the cost of living is much lower than the bay area, but even adjusting for that and things like healthcare coverage it still seems like a lower take home pay. Has this been people's experience generally? Not to say there aren't benefits to moving aside from pay (work life balance, etc) but has it been 'worth it' in your opinion? Logistically the path would be pretty clear, but it'd be great to have a comparison of salary/benefits/QoL

Assistant: From a purely financial standpoint, it won't make much sense to take a position in Germany. US salaries are much higher and healthcare in Germany while 'free' will be about 15% of your salary in taxes which is also higher than most US employer options. If you can get outsized career development or want the experience of living abroad the intangibles or future career growth could be net positive still but the pure financials for that time won't be. |

Assistant: There was a study done to convert a floating ice shelf into a massive airfield during WW11. Most fantasy and I think I saw in in Popular Mechanics. Something like insulating the ice with sawdust |
Human: If a steel bar has already yielded and is closer to the UTS and I do a second run on it, will I need the same amount of force to break it or less than than?
Assistant: Your question is more complicated than it sounds. As steel goes thru plastic deformation its cross section decreases. At the same time it'll probably work hardened. In many cases the steel will be stronger (in PSI or pascal), but seem weaker (in lbs or N) due to being narrower. |

Human: During interview I asked about work life balance and got "People with higher ambition spend more time". Red flag? Had a phone interview today and I asked about work life balance. He said when you are at work you work and when you are out that is your time followed by the statement above. Is that a red flag or am I reading too much into it. They also didn't do work from home since they are a "team". This is for a design solution and for reference Im currently in design for a different company and been working from home no problem for the past year. Thanks.
Assistant: That's a red flag for sure. Lol at not working from home because they are a "team". |

Human: What was the hardest lesson you learned in your engineering career? Plain and simple, something you wish you learned much earlier, or that has stuck with you ever since you discovered it?
Assistant: The job of an engineer is not to perform computations, analyze, draw things, or have good ideas. An engineer's job is to make things happen. The rest are just tools or steps along the way. So many engineers hit some kind of mental wall whenever they're asked to do something they don't know how to do or when their work reaches the end of whatever they specialize in. Just figure out how to do it and make it happen. Ask if you can't figure it out. Learn. Do it yourself next time. |
Human: What was the hardest lesson you learned in your engineering career? Plain and simple, something you wish you learned much earlier, or that has stuck with you ever since you discovered it?
Assistant: 1. Function over form. IMO, the key to success in a project engineering (especially as a young engr) role is constantly seeking feedback from and getting “buy in” from the folks that will implement, operate & maintain the equipment once commissioned. 2. Often the best ideas are the simplest. KISS 3. Realizing that you’re probably not the smartest person in the room. 4. Office politics is real. Learn how to strategically influence others to get what you want. 5. CYA. Document, document, document. |
Human: Do you feel like you’re making a difference to people’s everyday life? What are some examples where you know a difference was made? I want to study engineering because I want to make a difference in the world and also love math and science so this question has been on my mind.
Assistant: Automation. I help companies make higher quality products, faster. I get a particular amount of pride in the medical device applications I've worked on. Plus with so many products being manufactured overseas, the work I do helps keep the my local manufacturers competitive with the global market. |

Human: Did a career in Engineering become what you expected it to be? I've literally just finished my degree in Engineering at university, I chose to do it because at the time I wasn't too sure what I wanted to be but I was good at maths and physics and Engineering seemed to be a pretty flexible choice for a career. However, I have no idea what to do now, I don't know what job to look at, I don't know if I'll be happy being an Engineer. Did anyone feel the same but find after getting a job in Engineering everything turned out better than expected? Or does anyone know any career paths you wouldn't expect a degree in Engineering would help with?
Assistant: If you work in product development, you'll wish you had studied industrial design instead. At my company engineering is on the 12th floor, design is the 13th. They basically have a modern looking loft with artwork, natural lighting, open floorplan, kitchen, living room etc. The engineers get bland cubicles with blue walls and lots of overtime. |

Assistant: Biomedical here. I just graduated with an extra bonus--an invention disclosure. We are getting IRB approval now for human testing. It really is rewarding to see your work can directly affect people's lives. And then there's the NASA work I'll be doing as a grad student.... ;) I can definitely say I had no idea I would be on this track so early. Extremely rewarding. |
Human: Why is speed at sea measured in knots?

Human: Why does socket fuel, like hydrogen and oxygen, boil away on long missions? If the tanks are sealed, wouldn't the liquid boil until the vapor pressure increases to the equilibrium point at the current temperature?
Assistant: On *LONG* missions you generally don't use hydrogen/oxygen. You use hydrazine as a monopropellant. One of the nice features of hydrazine is that it will freeze into a solid in the cold vacuum of space. This means that if you're not going to use your thrusters for a few months/years (we're on a long mission, remember?) you can just let it freeze rock solid. Voila! No leaks! Just remember to turn on the heaters to thaw out your tanks a couple days before you plan on using your thrusters. |

Human: Do any materials have higher tensile strength than compressive strength? And if so, how is it used? Non-engineer here so excuse my amateur terminology. I was watching a video on why rebar is put into concrete. It showed how a concrete beam, when pushed down on, compresses at the top and stretches apart at the bottom, and it's the bottom where the crack shows first. I thought this was caused by basic angles, but he said it was because concrete can resist compression excellently but not stretching (i.e. tensile pressures), thus the cracks forming at the bottom where stretching occurs and not at the top where compression occurs. Is there any solid material that buckles under compression but has great tensile strength, such that it would crumble/fail from above first when a beam is pushed down on? Or is this impossible? If so, would they have any special uses?
Assistant: Gonna disagree with people just saying "ropes or fibers or cables" because yes, materials made in those geometries do not resist compressive force very well, but that's because of how long and thin they are, that property is not inherent in the material itself. Just the form factor. If you sectioned off a piece and ensured there was no bending and it could be stably compressed, the discrepency in tensile and compressive strengths would diminish greatly. |

Human: Can these 35-ton bricks in Giant Towers solve renewable energy’s biggest problem? Store energy created when the sun shines or the wind blows so it can be used later.

Human: I'm looking for very powerful motors (500W+ continuous power draw) but have some tight size restrictions and high radial loads. In my project of making electric roller skates I've been trying to get motors with sufficient torque which can fit my size restrictions. Currently I've been looking at geared brushless AC motors but for simplicity something like a <80mm diameter hub motor would be easier to implement but they are surprisingly hard to find. Does anyone know where I can find something along these lines or would manufacturing at my uni's workshop be the next best option?
Assistant: Maxon out runners might fit your needs But if you're looking to take up the radial wheel loads with the motor bearings, you're gonna have a bad time. Also, how did you arrive at >500w? Did you do the math on what you actually need? |

Assistant: Two searches that might help are electric scooter hub motors and quadcopter motors. The outrunner quadcopter motors can be really nice for high torque. Be aware that motor efficiency and mass go together, so motor mass and size versus battery mass and size turns into a fun optimization problem. Also check the Maxon EC Flat series, but they're not cheap. |
Human: Any Engineers out there also have this issue? I'm a biomedical engineer and throughout my life I've focused on school and getting a job because my family literally drilled it in my head that if i just finish school and get a good job, like the one i have now, it will be so easy to settle down and find a mate. Well I graduated in 2014 and I still have yet to find someone! Its gotten to the point where I hate even logging on to social media because it seems that every second one of my peers from high school or college are getting married or having gender reveal parties... I even pass up opportunities to go to gatherings because everyone there always seems to be coupled up and I'm usually the only one whose single. I really want to find someone already! All of my coworkers are already in relationships. Literally my days consist of waking up, going to work, coming home and going to sleep. And on the weekends I just stay home and tinker with some projects I'm working on. How do I even start? I feel like time is running out. I'm 29 freakin years old! I have a good job! What the hell man! Can anyone help guide me in anyway or at least share your experience and what you've been trying to do to get over it? I love being an engineer and love it's rewards but I am still missing the real prize I feel like!
Assistant: That's one heck of an engineering problem. |

Assistant: There are better sub Reddits related to dating advice. I advise online dating web sights. Find some people you're interested in meeting. Your message could be straight forward, e.g. request to meet in public place if you think you're interested too. Just spend a small amount of time, regularly every week after work, on the dating platform(s). Finally, get hobbies that get you out of the house. Just my ten cents. |
Human: Any engineers who work on an offshore rig, what is life like out there? I am asking because Im currently pursuing a PNG E degree. After talking to some people and doing some research, I learned that there is a good chance I will working on an oil rig after I graduate. I generally know how the rotations can go, but what is life like out in the middle of the ocean?
Assistant: Are there jobs offshore for EEs? I'd love to travel and like the binge and purge work schedule. |

What he did hate was the travel. He just got fecking sick of it. He had to go from Norwich to Schiphol airport, then onto Libya, from ... somewhere in Libya onto the camp. Just something to think about is travel. |
Human: Why did I kill myself in graduate level control systems courses when every controls engineer is ladder logic, PLC BS? Seriously, I do not understand this field. I have experience in grad school of robotic kinematics and control systems, but b ecause I've never seen a rockwell bradley PLC I have no controls experience. end rant I guess
Assistant: I want to learn PLCs for this reason. That, and because.... Have you ever used a microcontroller in the the real world? Once you add all the stuff to actually do it... You've invented a crappy PLC. Of course, I do more specialized stuff that MCUs really are appropriate for, but when I hear about PLC work i usually think "Everything should be more like that", to the point where I think I'd benefit from learning PLCs even if I never actually do move to industrial automation. |

Human: Aerospace/Defense: Interning for Textron Inc. or Harris Corp? Hello Engineers, I just signed up for Reddit because an internal conflict that I can't seem to find a clear answer for. I'm currently a sophomore at Purdue University and around mid-October, I landed my first internship offer! Textron Inc. is a pretty big name in the Aerospace/Defense Industry, as it parents Cessna, Beechcraft, Hawker, Textron Systems, etc. Needless to say, I was beyond excited to work for such an amazing company. They gave me 2 weeks to accept the offer, which I did without question. A week ago, I received a call from Harris Corp regarding another acceptance offer. Harris is another Fortune 500 company, and a big player in the industry. They work on GPS, microwave signals, and small satellites- and are currently under contract with NASA to build another satellite telescope. I have a week to accept this offer- and if you can infer, this is where the conflict lies. **My question: Should I revoke my current contract with Textron Inc. in favor of Harris?** Context: \- My goals are to work for Lockheed Martin, Boeing, Northrop, BAE, etc. \- Both companies pay the same hourly rate, but Textron is giving me a larger upfront housing stipend. \- Harris Corp is located in Palm Bay, Florida and Textron is going to be somewhere in the midwest (They haven't assigned ma a location yet) \- Textron is a very decentralized company, and have other companies like aviation, military technology, specialized vehicles (Off road vehicles), Arctic Cat (snowmobiles), Greenlee (lawnmowers). They are going to assign me a unit in the Spring, but I run the risk of not being placed in Aviation or the Defense side. \- Harris already told me exactly where I'll be working, and I know I'll be working on relevant technology I'm just curious to see what you, more established engineers would do in my position. All answers will be taken into account into my final decision. Thanks! \- Alex
Assistant: idk it seems pretty scummy to retract an offer after you already accepted. Textron is still a good company and you are a sophomore so you still have time. I'd say do textron this year and then next year switch it up with harris or another company so you can get different experiences. I haven't worked with textron at all but have interview with them a bunch and know some people who worked at bell and they seemed to like it. |

Human: For those of you who have a masters degree, how much of an advantage has it given you in the workplace?
Assistant: Many people get a master's and then work in a job they could get without a master's, and obviously this doesn't yield much a difference over a career. If you want some specialized job that requires learning that you are unlikely to get from a bachelor's, then getting a master's will be worth it on a personal level, as well as probably very rewarding financially. |
Human: For those of you who have a masters degree, how much of an advantage has it given you in the workplace?
Assistant: For my previous job (hardware/FPGA/embedded engineer) not much. But allowed to me to change into fields that would have been hard to get into with just a BSEE or many years of experience (specifically DSP). |
Human: Starting an Engineering career at 30yo? Degrees for Engineers that get their hands dirty? Hello! As the title suggests I am 30 years old (six months shy but I'm owning it), and am hoping to get some advice on becoming an Engineer at my age. Specifically I was hoping to get into 'Ecological Engineering' but midway through my second year of a BoE - Civil and Environmental, I'm starting to think I may be going for the wrong degree and that what I want to do isn't a real job. So with that I'm also looking for any guidance you all can give me on possible positions to aim for that may get me close to what I want. Sorry this post is so long, skip to the last paragraph if you just want to see my questions, but here's what I think is relevant/needed background information: I was a ground equipment mechanic in the US Air Force for just short of 10 years. For the first 8 I worked on just about everything at an airport other than the planes so I have general experience with diesel, turbine, and small gas engines, hydraulics, electrical, and all kinds of equipment inspection and maintenance. For the last 2 years I worked in an office as a safety/security/deployment manager so I think the civilian equivalent of personnel management or HR. Unfortunately, I was force retired in December, 2018 after reconstructive surgery on both ankles. (My legs are fine other than some nerve damage that I take light pain meds for, but basically the cartilage is gone from both ankles so the docs said they don't want me running anymore and the military just doesn't put up with that.) I was living in Spain at the time and only had about 2 months to make decisions, get all the paperwork approved and move countries so please forgive me for not doing enough research but I knew that I wanted to work in 'Ecological' Engineering ( building eco-friendly houses, buildings, even cities whatever.. my imagination was a bit out of control). I know many of you may ask why not Engineering Mechanics with my background, but I felt that although I did enjoy working in mechanics, Ecological Engineering is my dream and I just didn't see a way to match the two. So anyway, I applied for some Uni's, got accepted to a few, and eventually chose to move to Sydney, AT to attend the University of Technology Sydney for a BoE - Civil and Environmental. Now I'm midway through my second year and having a lot of doubts. I was accepted to a mentorship program and was lucky enough to get a mentor who works in Environmental Engineering. However, I now see that he works in an office full time and he has even told me that he only ever does paper/office work as he is a Consulting Engineer. He does not get to work on site or assist with the build at all as I had previously thought would be possible. I've also been to several Engineering Events now where everyone I talk to seems to do the same. He has told me to look into Contracting Engineering jobs but I have only been able to find general information so far and don't know if that's really much better or how to go about ensuring I end up as one. Although diesel maintenance wasn't my favourite I have always loved working with my hands, getting dirty and being exhausted at the end of a long work day, and seeing projects through from start to finish. I had thought, and really hoped, that as an 'Ecological' Engineer I would be able still do that while working on much larger projects, with lots of different people. I've worked both ends of the spectrum of manual labour and sitting at a desk for 10 hours and know that I want something in between. I also want to work in something that gives back to the environment while also creating/building to improve life for humanity, hence Ecological Engineering if possible. So my questions are these; which fields in engineering would allow for that type of work or would be the closest fit? And what steps should I take to ensure success as I have very little relevant background work and am starting at such a late age? Thanks in advance! I really appreciate any advice offered.
Assistant: If you want to get hands on, I’d say mechanical is the way to go. Civil or environmental engineers may do some field work, but more of it is on paper. With mechanical, you can get into a maintenance/reliability role where you can get dirty every day - if you want. Source: I work as a maintenance engineer, I get dirty every day. |

Assistant: So there are literally millions of jobs on the implementation side for engineers too. If outside is important consider looking at construction firms who do park building, remediation or just airport construction. There your user experience will count and you’ll be many steps ahead of your 20 year old classmates. |
Human: Engineers that get their hands dirty? Hello! Sorry for the wall of text coming up, I'm on mobile. Anyway, I'm curious about engineering fields where there is opportunity to be more hands on in mechanical aspects. I graduated in 2014 with a BS in physics, and minors in math and chemistry. Along the way I learned some basic CAD on ProE and it was enough (Also with the help of a connection) to land my first Mechanical Designing job which I worked until last March. The job also taught me SolidWorks and AutoCAD. Since leaving that job (long story why), I've been doing a lot of construction jobs and working in bars to make ends meet. I love getting dirty and being tired from exhaustion at the end of they day, but I want to use my mind more. I plan to go back to Grad school to get a masters in engineering, but I'm having a really hard time picking a direction that would be best for me. I worked both ends of the spectrum of manual labor and sitting at a desk for 10 hours. So my question is, which fields in engineering allow for the most of hands on work while still doing designing and working with the PLM cycle? I was thinking robotics, but at my age (24) and knowing next to nothing about the subject, I feel like it's a little too late. Civil engineering is also something I consider not in my interests, as I've worked in a machine shop throughout college and really liked that aspect. I would love to hear some personal anecdotes about how you fell into your field and decided it was for you. Thanks guys!

Anyway, I'm curious about engineering fields where there is opportunity to be more hands on in mechanical aspects. I graduated in 2014 with a BS in physics, and minors in math and chemistry. Along the way I learned some basic CAD on ProE and it was enough (Also with the help of a connection) to land my first Mechanical Designing job which I worked until last March. The job also taught me SolidWorks and AutoCAD. Since leaving that job (long story why), I've been doing a lot of construction jobs and working in bars to make ends meet. I love getting dirty and being tired from exhaustion at the end of they day, but I want to use my mind more. I plan to go back to Grad school to get a masters in engineering, but I'm having a really hard time picking a direction that would be best for me. I worked both ends of the spectrum of manual labor and sitting at a desk for 10 hours. So my question is, which fields in engineering allow for the most of hands on work while still doing designing and working with the PLM cycle? I was thinking robotics, but at my age (24) and knowing next to nothing about the subject, I feel like it's a little too late. Civil engineering is also something I consider not in my interests, as I've worked in a machine shop throughout college and really liked that aspect. I would love to hear some personal anecdotes about how you fell into your field and decided it was for you. Thanks guys!
Assistant: I work for a company that designs conveyors and conveyor belts. I'm in NPD. Half my time is designing ..the other half is building what I designed. Look for NPD type work. |
Human: Can I build a linear motor/linear actuator from a AC or DC motor? Hi there. I am new and stupid. I am also poor. A project I'm working on calls for a push pull engine, like a actuator. It needs a stroke of about five or ten inches, and the capability to push/pull around 5kg, pretty quickly. As linear actuators are ridiculously expensive, I was wondering if there were reasonably simple ways to build them. I am going to try something like the following image shows when I have time to build the parts and get to a hardware shop for some long bolts. http://i.imgur.com/T6QOP.png If you crazy kids have any far better, superior ideas, please let me know.
Assistant: Why not try a rack and pinion set-up |

Assistant: I got a lead screw type linear actuator, refurbished from something.. maybe you could find something similar. The motor is geared and has some sort of rotary encoder, but the stroke is probably only 3-4 inches. The motor is 12vdc or so. Here are pics: http://imgur.com/a/MvDn3 |
Human: Why do we need compressors to increase the pressure in jet engines? The question seems pretty easy but I haven't found many answers on the Internet. Why do we need the pressure of the airflow to be increased? How does jet engine benefit from it?
Assistant: Google Brayton cycle. You need to compress the gas primarily to raise the specific enthalpy of the gas before it enters the turbine giving the turbine more work to extract (for a fixed amount of specific combustion energy). This has the added benefit of raising the thermal efficiency of the engine. Edit: a word |
Human: Why do we need compressors to increase the pressure in jet engines? The question seems pretty easy but I haven't found many answers on the Internet. Why do we need the pressure of the airflow to be increased? How does jet engine benefit from it?
Assistant: The work done on an engine is done mostly by the expansion of gas. As gas expands at the back of the engine it pushes on the metal with a forward component. You get more expansion if you compress the air first. As a result, more of the energy goes into useful work. In other words you get more thermal efficiency with a higher compression ratio. |
Human: How do businesses fulfill their need for COBOL programmers for legacy applications? Do they just try to hire as many old timer programmers as they can? Are there any young programmers learning COBOL, and if so, do they learn it at their job or before getting hired? How many people are learning COBOL on their own time? Are businesses actively trying to port COBOL legacy code to newer languages?
Assistant: My oldest sister was lured out of retirement to return to Ford and help them with their Cobol systems. She's in her late sixties. Nobody is learning Cobol and companies won't do anything about it until they are absolutely forced to. |

Human: How long did it take for your first promotion? Just talking to some co-workers, and wondering how long it took for other engineers to go from their entry level job to another "rung of the ladder" at the same company.
Assistant: Never had a promotion because I change roles for a 20-30% pay raise every 3 years |
Human: How long did it take for your first promotion? Just talking to some co-workers, and wondering how long it took for other engineers to go from their entry level job to another "rung of the ladder" at the same company.
Assistant: I was hired Aug 2019 and had a new title by Nov 2020. It came with a 33% raise. On top of that, my company does 3-3.5% annual merit raises. |
Human: Which non STEM field would you suggest an engineering student to learn? I'm interested in fields like philosophy, sociology and psychology but i want a field that will benefit me in my future engineering career. What would you suggest?
Assistant: Writing/literature |
Human: Which non STEM field would you suggest an engineering student to learn? I'm interested in fields like philosophy, sociology and psychology but i want a field that will benefit me in my future engineering career. What would you suggest?
Assistant: If you want to do it for your own intellectual stimulation, I would suggest philosophy. If you want to do it for professional reasons, business or economics. |
Human: Do you regret studying engineering?
Assistant: Yep. Should have gone CS. |
Human: Do you regret studying engineering?
Assistant: In retrospect, computer science might have been the better choice given the availability of jobs. But then, I probably would have found myself sitting in a chair programming, thinking why I was such an idiot not to pursue a proper engineering career where I can get out of said chair once in a while. |
Human: What to ask for as a starting salary? To start off, I'm a college student trying to land an internship. I've been applying to places like crazy and this question always stumps me. I'm never sure what to put. I don't want to seem like I'm lowballing and are not confident in my skills as an engineer, but on the other hand I don't want to high ball and seem way too experienced. I know there's a lot of variables like experience and location, but I'm never sure what to put when asked this on applications. Thank you
Assistant: You don’t put a number at all. |

Assistant: That option is mainly for full time employees, they want to weed out people who want more salary than they are willing or able to give. Internships have a fixed hourly rate usually. Just put 0 or somthing reasonable like $20/hr. I can almost garuntee that it will never be mentioned in any interviews or when you get an offer. |
Human: Negotiation - How would you take or handle this response? I have recently been offered 65k salary + 5% bonus at an Aerospace company for a Manufacturing Engineer position. For reference, I am 3.5 years post graduation with <1 year experience professionally. After sending an initial negotiation email stating the average manufacturing engineer pay in my state, the above average increase in inflation, CPI, and COL in my state compared to the national average, and the vested 401k bonuses I'd be giving up at my current company, recruiting responded with the below.. "The offer we sent was based on your current position, work duties, and all information on your current resume, and then compared to your would-be peers, already in the role, and with like experience. If you wish to counter, please reply with an **updated resume** describing your reasoning for the merit in increase. Whether that be extra duties, specific projects worked, or education that might not be on your original resume. Compensation will want to see something they didn’t see initially to consider. Once received, I will forward your counter offer to our compensation team for evaluation and update you with their response ASAP" How would you take this response..? Obviously I applied with an updated resume... I could definitely go into more hard specifics about what I accomplished, but this seems like a nice way of saying "No." to me. Anyone have thoughts or suggestions..? Should I provide more details or just shut up and take the offer?
Assistant: Less than one year on the job, after graduating 3 1/2 years ago? You're in no position to bargain using average pay, you're experience is way below average. And looking to change jobs after less than a year isn't a good impression either. Do as others have recommended. Stay where you are for another year or so and then look. |

Human: Why does increasing derivative gain reduce damping ratio for first order system controlled by PID? I understand the derivation for the equation but it doesnt make sense to me conceptually. I thought the entire point of derivative gain was to reduce oscillations?
Assistant: For what it's worth, here's my Explain like I'm five years old. P responds to how far you are from the set point I responds to how long since you've crossed the set point (such as if you were overdamped) D responds to how quickly you are approaching the set point Of course, theory differs from practice. In practice, D almost always stands for "Don't Use" Source: I don't know what I'm talking about, just know the rule of thumb |

Human: Got offered a job but unsure about it I'm working right now for a drill and blast contractor. I've worked for them since graduation in civil engineering (about 3 years). It's been a fun experience, but I just feel no challenge and no self worth anymore (also no possibility to advance).So I applied to a job that seems extremely more interesting and more challenging and today I learned that I got the job (in construction management). The job is also where my father lives so that's a plus. Thing is they're not offering any better conditions. In fact, they're much lower than I expected. The HR woman sent me the conditions by email and said I could start as soon as possible. Should I call them and try to negotiate ? I was expecting a lot more, especially since construction management often requires crazy hours. It's a big risk I would be taking and there's unfortunately not much of a reward. I even though about going to grad school full time in structural eng. I'm sure a lot of you guys had a decision like this to take, especially at the beginning of your career. Can you tell me what you'd do in my situation, considering my job is starting to slowly eat my soul. Here are the conditions : salary : 62.5k 3 weeks vacation/year Cellphone + laptop provided Pickup truck provided Please comments. I really need some insights right now.
Assistant: Annual raises are dogshit. Promotions are horseshit. By far the biggest opportunity to increase your salary is when switching jobs. But switching jobs too often can make you seem flaky, unloyal, etc. Because of all that, I never take a new job unless it gives a pay increase that's big enough for me to feel completely comfortable taking it. |

Assistant: Always plan to negotiate salary and benefits! Always always always. Do research to find what the salary should be and bring it with you as ammo. |
Human: Hey mechanical engineers, is there really any benefit to letting your car engine warm up before driving?
Assistant: There are about a million threads covering this dilemma over on bobistheoilguy.com, your go-to site for oil questions. The bottom line is that there are no manufacturers that recommend long idle times before driving. Most manufacturers recommend less than a minute of idling, followed by gentle driving until the engine comes up to operating temp. Remember, it's not a choice between idling and wear, it's a choice between a protracted period of low wear and a much shorter period of higher wear. |

Assistant: The answer at freezing is different than the answer at 32 below. When it gets really cold everything that moves is going to be struggling for a while. |
Human: What are the possible career paths for a mechanical engineer which don't involve mechanical/machine design ?
Assistant: Like others have said, there are tons of options. One i haven’t seen listed is test engineer. I started my career in automotive design and worked with tons of mechEs who were test engineers and never touched CAD. |

Human: IS the defense industry full of bad managers? Does the defense industry tend to have worse technical engineer managers than the private industry? My prior manager was great, but my current one is so passive aggressive and simple minded. I can tell he is secretly racist along with very judgmental with the ideology of I see so it must be. He is a huge trump supporter even for illogical things defending him to the tee saying he is a genius with every move Trump makes. The guy always makes comments about "oh gosh this guy thinks he is a genius..." I was warned by other to not enter defense and this experience is making me regret so.
Assistant: So you've had two managers and want to blanket label the entire industry? |

Human: Since I only pay for the amount of water used in my home, and not the pump pressure, is there anything stopping me from putting a turbine on my water main to generate free power when running water? I'm aware that there will be a pressure drop across the turbine, but I'm unsure of how significant that will be compared to the energy potential
Assistant: Honestly, you can literally take bicycle pedals, put them under your chair and just pedal slowly during the day. You'd generate far more energy that way that by the pump thing you described. |

Human: Book for practical fluids system design for industry? Can anyone recommend a book that is a great guide for all things fluids/thermofluids system design that would be useful in industry? (Internal flows) Covering: - Fundamental but practical theory - Sizing of pumps, valves, heat exchangers, insulation etc - Thermo & fluids system modelling - Pressure drop analysis Does such a book exist? Or is this information all vastly spread in standards and supplier guides? Thanks in advance!
Assistant: Crane 410 technical paper is pretty much the Bible on this topic. A good (but not as good) secondary go to is the Cameron Hydraulic Data book. |

Human: What's the heaviest material that can be bought for the cheapest? If I had (eg) $10,000 to spend on pure weight, what can I buy? Cheapest:heaviest
Assistant: Do you have to be able to reach the material? I'm sure there are a few companies which would gladly write you a title for a thousand stars or so. My answer is stars |
Human: What's the heaviest material that can be bought for the cheapest? If I had (eg) $10,000 to spend on pure weight, what can I buy? Cheapest:heaviest

Human: As a mechanical engineer - how important is it to have basic programming knowledge? I'm a high school student and trying to figure out if I should do computer science related courses. Thank you! :)

Human: As a mechanical engineer - how important is it to have basic programming knowledge? I'm a high school student and trying to figure out if I should do computer science related courses. Thank you! :)
Assistant: Don’t worry about CS classes, you won’t be doing that type of programming. Learning Excel VBA, MATLAB, and even Python is the way to go. There will be plenty of it built into your degree, but yes programming is very important. During my mechanical degree almost every class used some type of programming. You’ll learn all the concepts and how to set up problems but transition into writing Matlab code to solve the problems. Even in Differential Equations we used Excel to solve half the stuff. |
Human: How useful/utilised is MATLAB in industry?
Assistant: Very useful in aerospace and the defense industry!!! Used for a lot of various niche uses, general analysis, and also the simulation of complex electronic systems like control systems and communications systems. |

Assistant: In aerospace, a lot |
Human: Do any corporate clients expect you to fill out *their* bullshit corporate processes? I'm seeing an annoying trend in my industry where corporate clients are trying to offload as much work to engineering firms. This includes engineers who work for a firm external to their company having to fill out THEIR company processes and forms on their behalf. At first engineering firms were contracted to just design, which was cool. Say the client is Shell (not really, but anyway). It's slowly trending towards: * Logging onto Shell's intranet using a secure remote logon to lodge management of change forms * Rooting around their Shell orgchart to contact the correct contact person / stakeholders to constrain a scope of works * Filling out other bullshit company forms * Facilitating risk assessments for them I get clients want to just manage, but they're expecting engineers external to their company to know the ins and outs of the operation to fill out their cumbersome processes. I've worked for client companies, and I followed all these processes directly - I couldn't imagine offloading this work, because it defeats the purpose of having these checks and balances.
Assistant: You think those protocols are annoying? Spend 5 minutes consulting in Defense or Pharma to really learn the true meaning of bullshit corporate processes. Pfizer and Merck have months of training *just to to log into their software* |

Human: When it comes to computer hardware, how low-level do you have to get before you need an understanding of multivariable/vector calculus and differential equations to understand how things work? Javascript is a high level programming language. C++ is more low level. More low level than that is C. More low level than that is x86 assembly. More low level than that is machine code. More low level than that is VHDL or Verilog. None of these these languages require much math beyond discrete mathematics (and maybe differential calculus) to learn. When does multivariable calculus/ODEs start becoming necessary to understand how computers work at a low level?
Assistant: Not at all. In university we did an EE course that went from basic electric gates all the way through "building" our own computer (virtual) with about 20 functions, cache, ram, and hdd and the whole shebang... and no calculus was involved. Not in "real" chip design you might need it to deal with heat dissipation or run length electrical decay / timing... but just to understand it you don't need it at all. |

Human: Disappointing moving from an Engineer to a Senior Engineer, was expecting more. I just got promoted to a senior engineer and frankly I am disappointed in my raise. I got 6% (2% for the actual promotion and 4% cause it was my annual raise). I'm a computer engineer, I've been there for five years, And moved up from $84K What have other people's raises been? Did you have a similar situation or am I just being a spoiled engineer?
Assistant: If you want more money you have to switch jobs. That's just the way society works today. |
