Objectives 1. To learn how to add vectors analytically. 2. To verify the first condition of equilibrium of an object which is acted upon by several coplanar forces. Preliminary Problem Which vector method would you use to add the three vectors FA, FB, and FC, where FA = 100 g, FB = 150g and FC = 120 g. Assume the unit of weight is grams for this exercise. (Note that we are using mass as weight, since they are proportional. Strictly speaking, we should change grams into Newton to represent forces but do not.) From your results, determine the equilibrant in polar notation. The equilibrant is the opposite of the resultant. It has the same magnitude but the opposite direction Use the paper provided to do this exercise. Note you may do the exercise on a piece of paper and place the picture on this page
