An overhead transmission line is erected across a span of 250 m on equal-level supports. The conductor has a diameter of 1.42 cm and a dead weight of 1.09 kg per meter. The line is subjected to a wind pressure of 37.8 kg/ m2 of the projected area, and 1.25 cm of the radial thickness of the ice. Assuming maximum working stress of 1050 kg/cm2, and one cubic centimeter of ice weighs 0.914 g, determine the vertical component of the sag under the following conditions: (i) still air (ii) combined effect of the ice and wind An overhead transmission line is erected across a span of 250 m on equal-level supports.
