An overhead line conductor having a parabolic configuration weighs 1.925 kg/m of length. The cross section area of the conductor is 2 cm² and the ultimate strength is 8000 kg/cm². The towers are 300 m apart having difference levels of 15 m. Calculate the sag from the taller tower, so that the factor of safety shall be 5. Assume that ice load is 1 kg/m run and there is no wind pressure.
