The document provides an overview of the concepts related to forces, including their classification, composition, and methods for determining resultant forces such as the parallelogram, triangle, and polygon laws. It discusses different types of forces—coplanar, non-coplanar, collinear, non-collinear, concurrent, non-concurrent, parallel, and non-parallel. An example is presented involving two forces at a specific angle, with a link provided for more detailed information on resultant forces.

2.  Introduction
 Classification of Forces
 Composition of forces
 Resultant Force

 Examples

4.  Coplanar and non-coplanar forces
 Collinear and non-collinear forces
 Concurrent and non-concurrent forces
 Parallel and non-parallel forces

5.  combining many forces with different magnitudes and directions
acting on a single plane or different planes or at a single point.

6.  single force obtained by combining many forces of different
magnitudes and directions to give the same effect as that of the
system of forces.

7.  Parallelogram law of forces
 Triangle law of forces
 Polygon law of forces

8.  Two forces of magnitude 50 kN and 80 kN are acting at a
point with an angle of 60o with each other.
