3.1. INTRODUCTION
In the previous chapter, we have been
discussing the effects of forces, acting on a body,
through their lines of action or at the point of their
intersection. But in this chapter, we shall discuss
the effects of these forces, at some other point, away
from the point of intersection or their lines of action.
3.2. MOMENT OF A FORCE
It is the turning effect produced by a force, on
the body, on which it acts. The moment of a force is
equal to the product of the force and the
perpendicular distance of the point, about which the
moment is required and the line of action of the force.
