Question

The water supply pipe shown in the figure is suspended from a cable using a series of close and equally spaced

hangers. The length of the pipe supported by the cable is 60 m. The total weight of the pipe filled with water is 6.5 k. With complete fbd.

a. What is the maximum sag (in m) at the lowest point of the  cable which occurs at mid length if the allowable tensileload in the cable is 2550 kN? Answer: 1.15

b. The sag of the cable at mid-length is 3 m. Find the maximum axial stress (in MPa) if the cable diameter

is 75 mm. Answer:  225
