Define the Shear or tangential stress.

1.	Define the Shear or tangential stress.
Answer» It comes in picture when successive layers of solid move on each other i.e., when there is a relative displacement between various layers of solid. (i) Here deforming force is applied tangential to one of the faces. (ii) Area for calculation is the area of the face on which force is applied. (iii) It produces change in shape, volume remaining the same.
