As shown, six power transmission cables hang freely between two towers to carry power across a canyon. The towers are spaced 465 ft apart and the bases of the towers are at the same elevation. Each cable has a uniform weight of 6 lb/ft and a maximum sag of 30 ft.

(a) Determine the maximum tension force that develops in each cable.

(b) Assuming that the cables pull on the tower arms at an angle of 10° from horizontal, determine the moment that develops at the base of the towers as a result of the tension forces in the cables.
