Bending moment diagram shows variation of bending moment along the length of a beam.

• Start by determining the reactions at the supports

• Identify the points of interest along the beam where the bending moment changes

• Calculate the bending moment at each point using equations of equilibrium

• Plot the bending moment values on a graph to create the diagram
