Question

(a) What is the value of stress within certain limit of
elasticity?
(1) Zero (ii) Proportional to strain (iii) inversely
proportional to strain (iv) does not depend
​

Answer 1

Answer:   What is the proportional limit on a stress strain curve?

The linearity limit (or the proportionality limit) is the largest stress value beyond which stress is no longer proportional to strain. Beyond the linearity limit, the relation between stress and strain is no longer linear.
