The bending moment diagram for a simply supported beam loaded in its centre is

When a body is subjected to a direct tensile stress (σ_x) in one plane accompanied by a simple shear stress (τ_xy), the maximum shear stress is

The maximum bending moment for the beam shown in the below figure, is

A shear stress across a plane, is always accompanied by a balancing shear stress across the plane and normal to it.
