Short note on System of forces
When a number of forces acts on a body, or group of bodies, they form a system of forces or force system. Depending upon the orientation of forces acting on a body the system of forces will be classified as:
(i) Coplanar Force System: When lines of action of all the forces of force system lies in the same plane, the force system is called coplanar force system.
(ii) Non-coplanar Force System: When lines of action of the forces of force system do not lie in the same plane, the force system is called as non-coplanar force system.
(iii) Collinear Forces: The forces, whose lines of action lie on same line are known as collinear forces.
(iv) Parallel Forces: The forces, whose lines of action are parallel to each other are known as parallel forces.
(v) Concurrent Forces: The forces, which meet at one point are known as concurrent forces. Concurrent forces may or may not be collinear.
(vi) Non-concurrent Forces: The forces, which do not meet at one point are known as non-concurrent forces.
