A transmission line conductor having a diameter of 19.5mm weights 0.85kg/m. The span is 275 meters. The wind pressure is 39 kg/m2 of projected area with ice coating of 13mm. The ultimate strength of the conductor is 8000 kg. Calculate the maximum sag if the factor of safety is 2 and the ice weighs 910 kg/m3.
