In the case of perfectly rigid bodies (deformation is negligible ), whatever may be the … WebDiamond is almost a rigid body. Hence Pr.6: A 10 KN force stretches a wire its elasticity is extremely large. and decreases its radius by 2%. Find the change in the Young’s modulus of Pr.8: What is the Young’s modulus the material of the wire.
WebAnswer (1 of 5): 1).When a body is subjected to some external force, there is some change of dimension of the body . The ratio of change of dimension of the body to the original dimension is known as strain. Since its the ratio of similar dimension therefore its dimensionless. 2). Elasticity is ... WebApr 3, 2024 · For a perfectly rigid body, whatever may be the stress, strain will be always zero. So young’s modulus will be infinite for a rigid body. So answer would be option A. Note: Practically perfectly rigid body will never exist. Rigid body is a thing which will never undergo any deformation whatever may be the force we apply.
