Apr 12, 2017 · Shear stress refers to a pressure endured by a material parallel to its face. Shear strength is the material's ability to endure this applied stress. If enough stress is applied to a body it may not return to its original shape. Picture a rubber band. If the band is stretched a little bit it will return to its original shape.
This is only the average stress, actual stress distribution is not uniform. In real world applications, this equation only gives an approximation and the maximum shear stress would be higher. Stress is not often equally distributed across a part so the shear strength would need to be higher to account for the estimate.
