Addition of three or more vectors through repeated application of the triangle rule
The polygon rule for the addition of three or more vectors.
Resultant of Several Concurrent Forces
Concurrent forces: set of forces which all pass through the same point. A set of concurrent forces applied to a particle may be replaced by a single resultant force which is the vector sum of the applied forces.
Vector force components: two or more force vectors which, together, have the same effect as a single force vector.
