As I've understood it engineers in other disciplines often have goto specs for various things: x inches of steel will hold such and such a weight material y can handle a current of z at gauge g, etc Why hasnt this been standardized in SENG? Maybe we should have simple components that are used in all cases and engineers become more like people playing with legos, fitting pieces together instead of inventing new blocks over and over.
