A transmission line has a span of 214 metres. The line conductor has a crosssection of 3.225 cm2 and has an ultimate breaking strengh of 2,540 kg/cm2 . Assuming that the line is covered with ice and provides a combined copper and ice load of 1.125 kg/m while the wind pressure is 1.5 kg/m run (i) calculate the maximum sag produced. Take a factor of safety of 3 (ii) also determine the vertical sag.
