Solution

Young's Modulus (E) is the ratio of longitudinal (normal) stress to the corresponding longitudinal strain within the elastic limit of a material.

E=Stress/Strain
 

Poisson's Ratio (ν) is the ratio of lateral strain to longitudinal strain within the elastic limit of a material.

 

Bulk Modulus (K) is the ratio of volumetric stress (hydrostatic pressure) to the corresponding volumetric strain within the elastic limit of a material.

Rigidity Modulus (G), also called Shear Modulus, is the ratio of shear stress to the corresponding shear strain within the elastic limit of a material.
