Forces F1 , F2 , and F3 act on the structure of the figure, shown in an overhead view. We wish to put the structure in equilibrium by applying a fourth force, at a point such as P. The fourth force has vector components Fh and Fv . We are given that a= 1.51 m, b = 3.75 m, c = 1.40 m, F1 = 11.2 N, F2 = 7.43 N, and F3 = 4.78 N. Find (a) magnitude of Fh, (b) magnitude of Fv, and (c) d.
