Actually, for electrical engineering, about the only physics you really need are wire sag, vectors (for hanging wires at angles,) tension, column loading, and such. The main science/math required is good ol' 12th-grade trigonometry. Most commercial electric power is three-phase, which makes all of us who used/use it thank progress for calculators and computers! No more looking up logarithm tables and using your K&E slide rule to compute functions. (I had the devil's own time with decimal places--too much like arithmetic, and then there was interpolation....) Anyway, calculating electrical load on a 3-phase line perfectly follows the Law of Cosines. BTW, I remember CNX^(n-1), but I don't remember how to apply it. I shocked my mother the first time I sped up driving around a curve (nothing coming in any direction.) She couldn't believe I did it to maintain the same velocity. I'm glad to see so many fellow nerds/nerdettes in this tavern! |
