1. Determine the reactions at the supports, the magnitude of the cable sag at joints B and E, the magnitude of the tension force in each segment of the cable, and the total length of the cable in Figure P6.1.
2. The cable in Figure P6.2 supports four simply supported girders uniformly loaded with 6 kips/ft. (a) Determine the minimum required area of the main cable ABCDE if the allowable stress is 60 kips/in.2. (b) Determine the cable sag at point B.
