(ii) An overhead line has a span of 160 m of copper conductor between level supports. The conductor diameter is 1.2 cm and has a breaking stress of 35 kg/mm². Calculate (a) the deflecting sag (b) the vertical sag. The line is subject to a wind pressure of 40 kg/m² of projected area and radial ice coating of 9.53 mm thickness. The weight of ice is 913.5 kg/m³. Allow a factor of safety of 2 and take the density of copper as 8.9 gm/cm³.
