1. The problem statement, all variables and given/known data Your given two designs for the same component. Design 1 has a stress pf 120 Mpa design 2 has a stress of 90Mpa. They are both made from the same material and the ultimate strength is 290Mpa and the yeild strength is 250 for both. The question is if yeild strength is the loss of function parameter which design would you pick, I would think to choose one b/c it can handle more stress but i dont know what that has to do with yeild strength could someone point me in the right direction.
