Question

Define Young's modulus,bulk modulus and rigidity modulus?

Answer 1

Answer:

Hey! This maybe helpful to you

Explanation:

young's modulus is a measure of elasticity . Given by the ratio of stress to strain on an object. ... Modulus of rigidity is defined as the ratio of shear stress to the shear strain: where = shear stress is the force which acts is the area on which the force acts = shear strain.

Answer 2

Young's modulus, Bulk modulus, and Rigidity modulus are all types of modulus of elasticity. All these are a measure of the elasticity of a material. Elasticity is the property by which the material when deformed by applying force regains its shape. Following are the definitions of types of modulus of elasticity:

• Young's Modulus: It is the ratio of tensile stress to tensile strain. It is defined when the axis of deformation and the axis of applying the forces are the same.
• Bulk Modulus: It is defined as the inverse of compressibility. It is measured when force is applied in all directions equally and the object is deformed equally in all directions.
• Rigidity modulus: It is also known as the Shear modulus of rigidity. It is measured when the volume of the object remains the same even on the application of force.
