A System of Forces:- 
When several forces act simultaneously on a body they constitute a system of forces. 

Coplanar Force System:-  
If all the forces in a system lie in a single plane, it is called a coplanar force system.

Coplanar Force System:-  
1. Coplanar Collinear Force System
2. Coplanar Concurrent Force System
3. Coplanar Parallel Force System
    a. Coplanar Like Parallel Force System
    b. Coplanar Unlike Parallel Force System
4. Coplanar Non-Concurrent Non-Parallel Force System

Coplanar Collinear Force System:- 
If the line of action of all the forces lies along, a single line and forces lie in the same plane then it is called a coplanar collinear system of forces.
