I am given the length, elongated length, original diameter and reduced diameter of a alloy bar, and the load carried. I need to calculate the mod of elasticity, poisson's ratio and the proportional limit for the material. Got the first 2, how do I calculate the proportional limit? My book it quite vague, as if its obvious, which I'm sure that it is but I missed it, can anyone tell me what i need to do? Thanks(adsbygoogle = window.adsbygoogle || []).push({});
