1. A cable ABCD is pulled at end E by a force P (Figure P6.12). The cable is supported at point D by a rigid member DF. Compute the force P that produces a sag of 2 m at points B and C. The horizontal reaction at support F is zero. Compute the vertical reaction at F.
2. Compute the support reactions and the maximum tension in the cable in Figure P6.13. The sag at midspan is 12 ft. Each hanger can be assumed to provide a simple support for the suspended beam. Determine the sag at points B and D.
