Q: According to Maxwell's reciprocal law, the deflection at point 'A' in a beam due to a unit force at point 'B' in the same beam is equal to deflection at point 'B' due to a unit_______.
  • A. Shear force at A
  • B. Bending moment at A
  • C. Couple at A
  • D. Force at A
Correct Answer: Option D - As per Maxwell reciprocal law, the deflection at point 'A' in a beam due to a unit force at point 'B' in the same beam is equal to deflection at point 'B' due to a unit force at A.
D. As per Maxwell reciprocal law, the deflection at point 'A' in a beam due to a unit force at point 'B' in the same beam is equal to deflection at point 'B' due to a unit force at A.

Explanations:

As per Maxwell reciprocal law, the deflection at point 'A' in a beam due to a unit force at point 'B' in the same beam is equal to deflection at point 'B' due to a unit force at A.
