WebAs the name implies, shear stress refers to the action of a force applied to a material, as indicated by equation 1. 𝞽 = F/A (1) where 𝞽 is the shear stress, F is the applied force, and A is the cross-sectional area parallel to the direction of the applied force. The above equation gives the average shear stress per unit area.
