The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is known as principle of resolution of forces.

Concurrent forces are those forces whose lines of action meet at one point.
The forces, which meet at one point and their lines of action also lie on the same plane, are known as co-planar concurrent forces
The forces which do not meet at one point and their lines of action do not lie on the same plane are known as non-coplanar non-concurrent forces
Co-planar concurrent forces are those forces which meet at one point and their lines of action also lie on the same plane
