Question
A cable with supports at the same elevation has a span of 300m. The cable weighs 75 N/m and the sag at midspan is 75 m. Determine The length of the cable.
Expert Solution
Step 1
Give data:
- The length of span, a = 300 m.
- The weight of the cable, w = 75 N/m.
- The sag at mid of span, h = 75 m.
Write the parabolic expression to calculate the length of the cable.
Here, h is the sag in cable and a is the span of cable.
