Question

The Young’s modulus of a perfectly rigid body is (a) unity (b) zero (c) infinity (d) some finite non-zero constant

Answer 1

Answer:

Young modulus = Stress / Strain

Since the body is perfectly rigid, it will not experience any change in length and hence strain tends to zero.

Thus, Y tends to infinity.

Hope it helps you !

Answer 2

● The value of Young's Modulus of Elasticity for a perfectly rigid body is Infinity.
