MODULUS OF RIGIDITY

Modulus it rigidity of ideal liquids is

Modulus it rigidity of ideal liquids is

Define rigidity modulus. Give the expression for rigidity modulus.

Y,B, G represent respectively the young.s modulus, bulk modulus and rigidity modulus of a body. If rigidity modulus is twice the bulk modulus, then

The Young's modulus and rigidity modulus of a metal are 40 GPa and 20 GPa respectively. Then the bulk modulus is

For most of the material , Young's modulus (Y) and rigidity modulus (G) are related as

For most of the material , Young's modulus (Y) and rigidity modulus (G) are related as

If the Poissions ratio of a substance is 0.25 then the ratio of its Youngs modulus and rigidity modulus is
