In engineers's point of view, shear stress is the force experience by a structure when it experience opposite acting load on it. It is also called tear stress.







  • A typical example is a simply supported beam. The support reacts to the load imposed on the structure.


  • Here, the shear force is zero because the support reaction neutralizes the load.


  • The max shear force is somewhere in the middle of the beam because there is no force opposing the external load acting on the beam.


  • The difference between normal stress and shear stress. Normal stress causes a change in size and aspect ratio.


  • The element changes from a rectangle in to another rectangle of different dimensions.


  • Shear stress causes a change in shape. It turns a rectangle in to a rhombus-like shape.
