This document defines shear force and bending moment diagrams, and provides examples of how to construct them for different beam loading conditions. It introduces axial force, shear force, and bending moment. Sample problems show the construction of shear force diagrams and bending moment diagrams for beams with point loads and uniform loads. Equations of equilibrium are used to solve for the forces and moments at different points along the beams.
