Modulus of elasticity for a perfectly elastic body is

Question

Modulus of elasticity for a perfectly elastic body is (A) Zero (B) infinity (C) 1 (D) 2

Tardigrade Admin · Accepted Answer

Young's modulus for a perfectly elastic body is infinity. For an elastic body, there is no deformation on the application of load. Therefore, the strain is equal to zero. The denominator becomes zero which leads to the infinite value of Young's modulus.
