Explanation:

Poisson’s ratio (μ) 

The ratio of lateral strain to the longitudinal strain for a given material, when the material is stressed within the elastic limit is its Poisson's ratio.

Bulk Modulus of Elasticity 

It is defined as the ratio of compressive to the volumetric strain of the body.

Modulus of Rigidity 

It is also known as Shear Modulus is defined as the ratio of shear stress to shear strain.
