System of Forces in Mechanics When multiple forces act on a body simultaneously, they form what is known as a system of forces. Force systems can be classified into various subdivisions, each with unique characteristics. Colinear Forces: Colinear forces are those that act along a common line. If these forces act in the same direction, they are termed "like colinear." Conversely, if they act in opposite directions, they are referred to as "unlike colinear." Coplanar Forces: Coplanar force systems involve forces that act within a single plane. There are two subcategories within coplanar forces: Concurrent Coplanar Forces: In this scenario, all forces intersect at a common point within the same plane. This arrangement is termed concurrent coplanar forces. Non-Concurrent Coplanar Forces: Unlike concurrent forces, non-concurrent co-planar forces do not intersect at a common point. However, they still act within the same plane. Non-Coplanar Forces: Non-coplanar force s
