Prove that elastic potential energy per unit volume is half stress into strain |
| Answer» We know, Young\'s modulus is the ratio of stress to strain. e.g., Y = stress/strain. if we assume a wire of length L, area of cross section A is fixed at one end and stretched by suspended a load M from the other end due to this extension of wire is x. = 1/2 × load × extension | |
