COPLANAR FORCE SYSTEM

Coplanar force system refers to the number of forces which remain in same plane. It is also stated as the number of forces in a system which remains in single plane. This force system can be concurrent, parallel and non-concurrent and non-parallel.

Concurrent coplanar force system

The concurrent coplanar force system refers to the number of forces which interest at a common point with their lines of action. It is not recommended that all the separate vectors are to meet at the common point. It is the simplest coplanar force system to resolve to determine the resultant force.

Show the concurrent coplanar force system as in Figure (1).

Parallel coplanar force system

The concurrent coplanar force system refers to the number of forces which are parallel to each other with their lines of action. This force system is mostly used in the analysis of simple beams with number of point loads.

Show the parallel coplanar force system as in Figure (2).

Non-concurrent and non-parallel coplanar force systems

Non-concurrent and non-parallel coplanar force systems refer to the number of forces which are not parallel and do not lie at the common point with their lines of action. It is not the simplest coplanar force system to resolve to determine the resultant force when compared to concurrent and parallel coplanar systems.

Show the Non-concurrent and non-parallel coplanar force systems as in Figure (3).
