What is Shear Stress?

Shear Stress :- Shear Stress is defined as the Shear force that is applied to body with respect that it opposes the sliding effect on the body , that creates Shear Stress.

                                             OR 

Shear Stress is defined as the Shear force is acting on a body that opposes sliding effect with respect to cross sectional area of the body, is called Shear Stress.

                                 Fig - Shear Stress

It is denoted by τ . It's SI unit is N/mmᒾ .

here                     Shear Stress = Shear force / Cross section area
                                              τ = Fₛ  / Area

                                           S.I = N/mmᒾ
