The right support of a cable is located 45 m below
the left support. The horizontal distance between supports
is 250 m. The lowest point on the cable is 15 m below the
right support. If the maximum tension in the cable result-
ing from a uniformly distributed load w along the hori-
zontal is 850 kN, determine The length of the cable.
