Question 116

Which statement about the moment of a force is correct?

A

The SI unit of the moment of a force is the Newton per meter (N/m\text{N/m}N/m)

B

For a rigid body to be in rotational equilibrium, the sum of clockwise moments about any pivot must be greater than the sum of anticlockwise moments

C

The moment of a force depends on both the magnitude of the force applied and the perpendicular distance from the pivot to the line of action of the force

D

If the perpendicular distance of a constant force from the pivot is doubled, the moment of the force is halved
