A cantilever beam $\textbf{PQ}$ of uniform flexural rigidity (EI) is subjected to a concentrated moment M at $\textbf{R}$ as shown in the figure
The deflection at the free end $\textbf{Q}$ is
- $\large\frac{ML^2}{6EI} \\$
- $\large\frac{ML^2}{4EI} \\$
- $\large\frac{3ML^2}{8EI} \\$
- $\large\frac{3ML^2}{4EI} $
