The Young’s modulus of a material is 10^11 Nm^-2 and its Poisson’s ratio is 0.2. The modulus of rigidity of the material is

Young’s modulus (Y): It is the modulus of elasticity related to change in length of an object like a metal wire, rod, beam, etc., due to the applied deforming force.

Within elastic limit, the ratio of lateral strain to the linear strain is called the Poisson‘s ratio.

No Young’s modulus Bulk modulus Modulus of rigidity i It is the ratio of longitudinal stress to longitudinal strain. It is the ratio of volume stress to volume strain. It is the ratio of shearing stress to...

Modulus of rigidity indicates resistance offered by solid to change in its shape.

Given: L = 40 cm = 0.4 m, F = 2000 N = 2 × 103N l = 0.5 cm = 0.005 m, A = L2 = 0.16 m2 To find: Modulus of rigidity...
