3. A transmission line has a span of 150 m between level supports. The cross-sectional area of the conduc- tor is 1-25 cm and weighs 100 kg per 100 m. The breaking stress is 4220 kg/cm. Calculate the factor of safety if the sag of the line is 3-5 m. Assume a maximum wind pressure of 100 kg per sq. metre. [4]
