Young’s modulus of a perfect rigid body is

Question

Young’s modulus of a perfect rigid body is (A) Zero (B) Unity (C) Infinity (D) Between zero and unity

Tardigrade Admin · Accepted Answer

Young’s modulus = stress/strain, and for a perfect rigid body we know that strain is equal to 0 and hence Young’s modulus of a perfect rigid body becomes Infinity.
