Maximum deflection in cantilever due to pure bending moment M at its end is
- A. $ML²/2EI$
- B. $ML²/3EI$
- C. $ML²/4EI$
- D. $ML²/6EI$
Answer: A. $ML²/2EI$
Explanation: For cantilever with moment M at free end, curvature is constant $M/EI$. Deviation from tangent $\delta = Area \times \bar{x} = (ML/EI) \times L/2 = ML²/2EI$.
