The given figure shows a cantilever of span 'L' subjected to a concentrated load 'P' and a moment 'M' at the free end. Deflection at the free end is given by

Figure for question 55, ISRO Mechanical & Aerospace 2011

  • A. $PL²/2EI + ML²/3EI$
  • B. $ML²/2EI + PL²/48EI$
  • C. $ML²/3EI + PL²/2EI$
  • D. $ML²/2EI + PL³/3EI$

Answer: D. $ML²/2EI + PL³/3EI$

Explanation: Superposition of deflection due to Point load ($PL³/3EI$) and Moment ($ML²/2EI$).
