This text book is absolutely horrible. I'm a third-year Mech Eng student. I've taken plenty of classes on hard subjects, so I know when a text book just plain sucks. This book does a pathetic job of explaining examples and basic concepts. I've spent hours trying to figure out assumptions that they should have just mentioned in the first place. And the poorly explained examples don't prepare you for the actual chapter problems. Because of the "wordy" writing style of the authors, basic concepts sound more complicated than they actually are; getting through the reading is a slow and tedious process.The book is utterly sterile. The only colors you'll see inside it are black and a little blue; there isn't even a picture of an actual circuit in this book. It's like it's writen for a machine.
