60 m B
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.
1. What is the maximum sag (in m) at the lowest point of the cable which occurs at mid length if the allowable tensile load in the cable is 2550 kN? (Answer: C. 1.15) and if 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: C. 225). With fbd.
2. The sag of the cable at mid length is 2 m. If the allowable tensile load in the cable is 2000 kN, how much additional load (in kN/m) can the cable carry? Answer: A. 2.31
