System of Forces (Engineering Mechanics)

System of Forces:

When two or more than two forces act on a body, they are said to form a system of forces

Following are the various system of forces:

Coplaner forces :

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

Concurrent forces :

 The forces, which meet at one point, are known as concurrent forces.

Coplaner concurrent forces :

 The forces, which meet at one point and their lines of action lies on the same plane, are called coplaner concurrent forces.

Coplaner non-concurrent forces :

 The forces, which do not meet at one point but their lines action lie on the same plane, are known a coplaner non-concurrent forces.

Non-coplaner 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-coplaner concurrent forces.

Non- coplaner non-concurrent forces :

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