Question

a. An overhead line has the following data: Span length = 160 m Conductor diameter = 0.95 cm Weight per unit length of the conductor = 0.65 kg/m Ultimate stress = 4,250 kg/cm^2 Wind pressure = 40 kg/m^2 Safety factor = 5 Calculate the sag. b. Derive the expression for the lowest point of the catenary curve if the supports are at different levels. Given that the weight of the conductor = 0.35 kg/m. The maximum allowable tension = 800 kg. The span length = 160 m and the safety factor = 2. Find the minimum point of the catenary if the supports are at 70 m and 60 m.

Description: a an overhead line has the following data span length 160 m conductor diameter 095 cm weight per unit length of the conductor 065 kgm ultimate stress 4250 kgcm2 wind pressure 40 kgm2 safety 47638

          a. An overhead line has the following data:

Span length = 160 m
Conductor diameter = 0.95 cm
Weight per unit length of the conductor = 0.65 kg/m
Ultimate stress = 4,250 kg/cm^2
Wind pressure = 40 kg/m^2
Safety factor = 5

Calculate the sag.

b. Derive the expression for the lowest point of the catenary curve if the supports are at different levels. Given that the weight of the conductor = 0.35 kg/m. The maximum allowable tension = 800 kg. The span length = 160 m and the safety factor = 2. Find the minimum point of the catenary if the supports are at 70 m and 60 m.
