1. The problem statement, all variables and given/known data I was told that yield point is a point which the material which will have an appreciable elongation of yielding without any increase in load . my question is If there's no increase load , how can the material elongate ? 2. Relevant equations 3. The attempt at a solution IMO , it's wrong.... can somone clarify ? if there's no force applied , how can the material elongate itself ?
