what is modulus of rigidity and shear modulus? What do they define?

The Modulus of Rigidity, also known as Shear Modulus, is a measure of a material's resistance to shearing or twisting forces. It is the ratio of shear stress to the corresponding shear strain within the elastic limit.
The Modulus of Rigidity is an important material property that helps determine a material's ability to withstand shearing or twisting forces. It is commonly used in engineering calculations to determine the stability and strength of structures and components.
The Modulus of Rigidity can be calculated by dividing the shear stress by the shear strain. It is typically expressed in units of force per unit area (such as N/m^{2} or Pa).
The Modulus of Rigidity can be affected by various factors, including the type of material, its microstructure, and its temperature. Generally, materials with stronger intermolecular forces and a more rigid structure will have a higher Modulus of Rigidity.
The Modulus of Rigidity is a measure of a material's resistance to shearing or twisting forces, while the Modulus of Elasticity (also known as Young's Modulus) is a measure of a material's stiffness under tensile or compressive forces. Both are important properties in understanding a material's behavior under different types of stress.
