The Modulus of rigidity of Bar is a measure of a material’s ability to resist deformation under shear stress, indicating its stiffness and structural integrity. And is denoted by G. Modulus of Rigidity of Bar is usually measured using the Megapascal for Pressure. Note that the value of Modulus of Rigidity of Bar is always positive. Typically, the value of Modulus of Rigidity of Bar is greater than 0.
