Shear stress (often denoted by τ (Greek: tau)) is the component of stress coplanar with a material cross section. It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material … See more The formula to calculate average shear stress is force per unit area.: $${\displaystyle \tau ={F \over A},}$$ where: τ = the shear stress; F = the force applied; A = the cross … See more Wall shear stress Wall shear stress expresses the retarding force (per unit area) from a wall in the layers of a fluid flowing next to the wall.
