Coplanar Forces:

While the disposition of the forces is such that these work in one plane, they are referred to like coplanar forces.

Composition

If a system of coplanar forces is working on a body, its entirety effect is usually expressed in terms of its resultant. The procedure of finding the resultant of any number of forces is called as the composition of forces. Force being a vector quantity, the resultant of the system of forces may be found out using vector algebra, for example. if the resultant of two forces is to be found, after that the law of parallelogram of forces is utilized.
