Consider the following statements:

If at section distant from one of the ends of the beam, M represents the bending moment, V the shear force and w the intensity of loading, then

1. dM/dx = V

2. dV/dx = w

Of these statements:

A) 1 and 3 are correct

B) 1 and 2 are correct

C) 2 and 3 are correct

D) 1, 2 and 3 are correct
