Q

is a single force which can replace two or more forces and produce the same effect on the body as the forces. Many forces can be composed into one single Resultant Force and this is known as:

A

COMPOSITION OF FORCES

38
Q

As many forces can be composed into one single Resultant, so can a single Force be replaced by two forces acting in directions which will produce the same effect as the single force. This breaking of the force into two forces is called

A

RESOLUTION OF A FORCE

39
Q

The law states that, If three forces acting at a point are in equilibrium, they can be represented in magnitude and direction by the sides of a triangle taken in order.

A

TRIANGULAR LAW OF FORCES

40
Q

states that, If a number of forces acting simultaneously on a particle/ body (concurrent forces) can be represented in magnitude and direction by the sides of a polygon taken in order, their resultant may be represented in magnitude and direction by the closing side of the polygon taken in opposite order.
