Question

Young,s modules of elasticity of a perfectly rigid body

Answer 1

Answer:

Young's Modulus = Stress/Strain, Since a perfectly rigid body won't yield any strain, irrespective of amount of stress, it's Young's modulus is infinite.

Explanation:

Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line. ... A low Young's modulus value means a solid is elastic.

Answer 2

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