Classification of force:

Single force is of two types that is, Tensile and compressive. Generally in a body several forces are acting. When a number of forces of different magnitude and direction act upon rigid body, then they are form System of Forces, These are given below

Coplanar Force System: The forces, the lines of action of which lie on the same plane, are known as coplanar forces.

Non-Coplanar Force System: The forces, the lines of action of which do not lie on the same plane, are known as non-coplanar force system.

Concurrent Forces: All forces of this kind, which act at one point, are known as concurrent forces.

Coplanar-Concurrent System: All such forces the line of action of which lies in one plane and they meet at one point are called as coplanar-concurrent force system.

Coplanar-Parallel Force System: If the lines of action of forces are parallel to each other and they lie in same plane then the system is known as coplanar-parallel forces system.

Coplanar-Collinear Force System: All forces of this kind whose line of action lies in one plane lie along single line then it is called as coplanar collinear force system.

Non-concurrent Coplanar Forces System: All forces of this kind whose line of action lies in one plane but they do not meet at one point, are called as non concurrent coplanar force system.
