ABSTRACT

When a beam is subjected to a transverse load, either a point load or an evenly distributed load along its length, a bending stress will exist within the beam cross section.

Considering the cantilever of a uniform section, as shown in Figure 1.1, subject to a bending moment, the bending stress will be zero at the neutral axis. The stress in the upper surface is in tension and the lower surface is in compression when subject to the bending moment.
