- The 110-lb traffic light is suspended from two identical cables AB and BC, each weighing 0.80 lb/ft. If the maximum allowable horizontal force exerted by a cable on a vertical post is 170 lb, determine the shortest possible length of each cable and the corresponding vertical distance h.Determine the maximum weight of the bucket that the wire system can support so that no single wire develops a tension exceeding 100 lb.If the system shown is to be in equilibrium, determine the following: (a) the tension in cable ABC, (b) the force P acting at Hook C, (c) the weight of block A, and (d) the magnitude of the force F. The change in length of Spring 1 is equal to 0.12 ft. Force P is 1/2 the magnitude of the compressive force in spring 2. The compressive force in spring 3, is 1/3 the magnitude of the force in spring 2. The weight of Block G is 1000 lb and the spring constant for all springs is 7000 lb/ft.
