1. The cable in Figure P6.3 supports girder DE uniformly loaded with 4 kips/ft. The supporting hangers are closely spaced, generating a smooth curved cable. Determine the support reactions at A and C. If the maximum tensile force in the cable cannot exceed 600 kips, determine the sag at midspan.
2. (a) Determine the reactions at supports A and E and the maximum tension in the cable in Figure P6.4. (b) Establish the cable sag at points C and D.
