Modulus of rigidity of ideal liquids is

Modulus of rigidity is also called shear modulus represented by G which is the ratio of shearing stress (stress due to tangential force) to shearing strain.


Only solids exhibit shearing as they have a definite shape. Liquids cannot show shearing as they do not have definite shape and cannot be subjected to tangential force.
