##### 4.5 SHEAR FORCE AND BENDING MOMENT OF CANTILEVER BEAMS

In a cantilever beam, shear force at any section is equal to the sum of the loads between the sections and the free end. Bending moment at a given section is equal to the sum of the moments about the section of all the loads between the section and the free end of the cantilever.

#### 4.5.1 Cantilever Beam Subjected to a Concentrated Load at the Free End

A cantilever beam AB carrying a concentrated load *W* at the free and B (Figure 4.17) is considered. Any section *x-x* at a distance *x* from the free end is taken.
