Cables - Problem No 1 (supported on the same level & subjected to Uniformly Distributed Load ( UDL )

Question - A bridge cable is suspended from towers 80 m apart and carries a load of 30 KN/m on the entire span. If the maximum sag is 8 m, calculate the maximum and minimum tension in the cable. Also find the length of the cable. If the cable is supported by saddles which are stayed by wires inclined at 30^o to the horizontal, determine the forces acting on the towers. If the same inclination of back stay passes over pulley, determine the forces on the towers. Height of the tower is 10m
