Question

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

Answer 1

Explanation:

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.

Answer 2

Young modules -

Definition: It is defined as the ratio of tensile stress or compressive stress to the corresponding strain within elastic limit. It is denoted by symbol E. It is also known as modulus of elasticity or elastic modulus.

The SI unit of Young’s modulus is N/mm2.

Modules of rigidity -

Definition: It is defined as the ratio of shear stress to corresponding shear strain within elastic limit. It is also known as shear modulus. It is represented by C or G or N.

The SI unit of C is N/mm2.

Bulk modules -

Definition: It is defined as the ratio of direct stress to the corresponding volumetric strain within the tic limit. It is denoted by K.

The SI unit of C is N/mm2.

its the answer....
