Physics - Elasticity Question with Solution | TestHub

(a) $Y$ is a property of the material only, so (a)$\to$1. This is correct.

(b) Breaking stress is a property of the material only, so it is 1 and not 1,4.

(c) Strain $=\frac{F}{AY}$ depends on force, radius and material (1,3,4), so (c)$\to$1,3 is incomplete.

(d) $U=\frac{1}{2}(\text{stress})(\text{strain})(\text{volume})$ depends on material, length, radius and force (1,2,3,4), so (d)$\to$2,4 is incomplete.
