The bending moment diagram for a cantilever whose free end is subjected to a point load will be of shape:- Correct Answer Triangle

Consider a cantilever of length l carries a concentrated load ‘w' at its free end:

Taking moments about the section:

M = - Wx

The maximum bending moment occurs at the fixed end i.e. M = -WL

Important point:

Cantilever beam with uniformly distributed load:

The shape of shear force diagram is triangle and shape of bending moment diagram is parabola.
