Question

Which one of the following statements is correct?

• A. Shear force is the first derivative of bending moment.
• B. Shear force is the first derivative of intensity of load.
• C. Load intensity on a beam is the first derivative of bending moment.
• D. Bending moment is the first derivative of shear force.

Answer 1

The correct option is A Shear force is the first derivative of bending moment.

$\frac{dV}{dx}=-wand\frac{dM}{dx}=V$
