on it. 2. From a single point, five sets of horizontal wires are radiating, viz., the first due north, the second 75° northwest, the third 75° southwest and the fourth 30° southeast. The tension at these four sets of wires is 100 N, 60 N, 80 N and 120 N, respectively. Find the direction of the fifth wire, its tension and position. 3. Use Varignon's Theorem to find the moment that the force shown in Fig. 1 exerts about point B. 30 mm 20 mm Fig. 1 D 20? 200 N
