SYSTEM OF FORCES

When two or more forces act on a body, they are called to form a system of forces. Following
systems of forces are important from the subject point of view :

1. Coplanar forces. The forces, whose lines of action lie on the same plane, are known as
coplanar forces.

2. Collinear forces. The forces, whose lines of action lie on the same line, are known as
collinear forces.

3. Concurrent forces. The forces, which meet at one point, are known as concurrent forces. The concurrent forces may or may not be collinear.

4. Coplanar concurrent forces. The forces, which meet at one point and their lines of action
also lie on the same plane, are known as coplanar concurrent forces.

5. Coplanar non-concurrent forces. The forces, which do not meet at one point, but their
lines of action lie on the same plane, are known as coplanar non-concurrent forces.

6. Non-coplanar concurrent forces. The forces, which meet at one point, but their lines of
action do not lie on the same plane, are known as non-coplanar concurrent forces.

7. Non-coplanar non-concurrent forces. The forces, which do not meet at one point and their
lines of action do not lie on the same plane, are called non-coplanar non-concurrent forces.
