ABSTRACT

Shear force and bending moment diagrams: When loaded by transverse loads, a beam develops internal shear forces and bending moments that vary from position to position along the length of the beam. To design beams, it is necessary to know the variations of the shear force and the bending moment, and the maximum values of these quantities. The shear forces and bending moments can be expressed as functions of their position x along the length of the beam, which can be plotted along the length of the beam to produce shear force and bending moment diagrams.
