“What happens when stress is applied parallel to the surface area of a material?”
Any force acting upon a three-dimensional object will produce an internal stress. However, how do engineers classify the types of stress that are parallel to the material’s surface area? Well, after many years of research, this phenomenon has been classified as a shear stress. A shear stress will produce a shear strain in the object proportional to the object’s modulus of rigidity, which can be symbolically represented with the equation (Tau = G*(Gamma), with (Tau) being the shear stress (Gamma) being the shear deformation and g being the modulus of rigidity. The higher a material’s shear strength is, the more it will be able to resist shear strength.
