Modulus of Rigidity, or Shear Modulus, is an experimentally derived number that represents the degree of elasticity a material displays under shear stress. Shear Modulus is important to various engineering problems, such as the question of how much a set of connections will yield in a vehicle when loaded. The formula for Modulus of Rigidity is a material's shear stress divided by shear strain. The process varies slightly, depending on whether the shear stress is due to a linear force or to torque.
