System of forces | Different types

When two or more than two forces of different magnitude and different directions act on the body they form a system of forces. Depending upon plane and direction the different types of system of forces categorize are following below. 

System of forces:

• Coplanar forces

If all the forces in the system lie in a single plane or whose line of action lies on the same plane are known as coplanar forces. 

• Concurrent forces 

The forces that are meet at one point or if the line of action of all the forces in a system passes through a single point are known as concurrent forces. 

• Coplanar concurrent forces

The forces that are meet at one point and their line of action also lie on the same plane are known as coplanar concurrent forces. 

• Coplanar parallel forces 

The forces are parallel to each other and lie in the single plane are known as coplanar parallel forces.  

• Coplanar like parallel forces

The forces are parallel to each other and lie in the single plane and are acting in the same direction are known as coplanar like parallel forces. 

• Coplanar non-concurrent forces

All the forces lie on the same plane but which are not meet at one point are known as coplanar non-concurrent forces. 

• Non-coplanar concurrent forces

The line of action of all the forces do not lie on the same plane and meet at one point are known as concurrent non-coplanar forces.

• Non-coplanar non-concurrent forces

The line of action of all the forces do not lie on the same plane and meet at one point are known as non-coplanar non-concurrent forces. 

• Non-coplanar parallel forces

The forces are parallel to each other but no in the same plane are known as non-coplanar parallel forces. 

• Collinear forces

The line of action of all the forces lie along the line are known as collinear forces.
