The moment of a force about a given axis depends:
(a) only on the magnitude of force
(b) Only on the perpendicular distance of force from the axis
(c) neither on the force nor on the perpendicular distance of force from the axis
(d) both, on the force and its perpendicular distance from the axis.
The moment of a force about a given axis depends on both the force and its perpendicular distance from the axis. So, the correct choice is (d).
