Parallelogram of force

From Wikipedia, the free encyclopedia

Main article: Vector addition

The parallelogram of forces is a method for solving (or visualizing) the results of applying several different forces to an object. It utilizes the principles of vectors to solve this problem called vector addition. For example, see Figure 1. This construction has the same result as moving F2 so its tail coincides with the head of F1, and taking the net force as the vector joining the tail of F1 to the head of F2. This procedure can be repeated to add F3 to the resultant F1 + F2, and so forth.
