Forces F1, F2, and F3 act on the structure of 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 = 2.0 m, b = 3.0 m, c = 10 m, F1 = 20 N, F2 = 10 N, and F3 = 5.0 N. Find

(a) Fh

(b) Fv and

(c) d.
