Shear force diagram shows the variation of shear force along the length of a beam, while bending moment diagram shows the variation of bending moment.

• Shear force diagram is a graph of shear force vs. distance along the beam.

• Bending moment diagram is a graph of bending moment vs. distance along the beam.

• Shear force changes sign at point of concentrated load or support reaction.

• Bending moment is zero at point of concentr
