Loads result in: a shear force (from the shear stress distribution) + a bending couple (from the normal stress distribution)
Normal stress is often the critical design criteria S M I c M I My m x = = = σ Requires determination of the location and magnitude of largest bending moment

Shear force and bending couple at a point are determined by passing a section through the beam and applying an equilibrium analysis on the beam portions on either side of the section.
