Topic: Strength of Materials
Shear force is
- A. Rate of change of loading
- B. Sum of bending moments
- C. Rate of change of bending moment
- D. None of the above
Answer: C. Rate of change of bending moment
Explanation: Shear force $F$ is mathematically equal to the rate of change of bending moment with respect to distance $x$, i.e., $F = \frac{dM}{dx}$.
