Question

what is Young's modulus of elasticity bulk modulus of elasticity and modulus of rigidity ​

Answer 1

Answer:

The ratio of longitudinal stress to longitudinal strain is called Young's modulus of elasticity in the elasticity limit.It is represented by Y.

Young's modulus of elasticity Y=  Longitudinal strain/ Longitudinal stress  

​  

 

Answer 2

Answer:

young's modulus is a measure of elasticity . Given by the ratio of stress to strain on an object. bulk modulus is the relative change in the volume of a body produced by a unit compressive stress acting uniformly over its surface.
