A normal dose of caffeine is about 50 mg to 200 mg. Caffeine works best when you take it on an intermittent, off-and-on basis. Higher doses can have much more potent effects. A dose of 500 mg or 600 mg of caffeine can affect you much like a low dose of an amphetamine.
This means the 25,300 American engineers employed in this field earned an average hourly wage of $43.90. The bottom ten percent earns as low as $53,120, while the top ten percent of materials engineers earn as much as $144,720 every year. Embed This Image On Your Site(copy code below):
Junior engineers make between 40 and 50 thousand dollars per year. Regular engineers make between $50 -70 tho â¦ usand and master engineers make between $70 to 95 thousand. An electrical engineer will make an average of 70,000 dollars a  year.How much an electrical engineer makes depends largely on  experience, education and the industry in wh â¦ ich the person chooses  to work.     I would say $ 60,000 is a low estimate since the BLET national agreement pays around $ 2600 â¦ per every two weeks on the extraboard. That alone is $68,000 per year for an extraboard engineer. Yard enginners tend to make a little less but road engineers make a lot more.
