Stresses in Right hand Crankweb

The right-hand crank web is subjected to the following stresses:
(i) Bending stresses in the vertical and horizontal planes due to radial component Pr and tangential component Pt respectively.
(ii) Direct compressive stress due to radial component Pr.
(iii) Torsional shear stresses.

What is shear stress?

When an external force acts on an object, It undergoes deformation. If the direction of the force is parallel to the plane of the object. The deformation will be along that plane. The stress experienced by the object here is shear stress or tangential stress.
