**Introduction:**

A uniform cantilever of flexural stiffness El and length L carries a vertical concentrated load Wat the free end,

**Description:**

The bending moment a distance z from the built-in end is

At the end z = 0, there is zero slope in the deflected form, so that dv/dz = 0; then equation gives A = 0. Furthermore, at z = 0 there is also no deflection, so that B = 0. Then
