5. A transmission line has a span of 250 m between supports, the supports being at the same level. The conductor has a cross-sectional area of 1.29 cm2. The ultimate strength is 4220 kg/cm2 and factor of safety is 2. The wind pressure is 40 kg/cm2. Calculate the height of the conductor above ground level at which it should be supported if a minimum clearance of 7m is to be kept between the ground and the conductor. [10-24 m] 6. A transmission line has a span of 150 m between level supports. The conductor has a cross-sectional area of 2 cm2. The ultimate strength is 5000 kg/cm2. The specific gravity of the material is 8.9 gm/cm3. If the wind pressure is 1.5 kg/m length of the conductor, calculate the sag if factor of safety is 5. [3.5 m]

5. A transmission line has a span of 250 m between supports, the supports
being at the same level. The conductor has a cross-sectional area of 1.29 cm2.
The ultimate strength is 4220 kg/cm2 and factor of safety is 2. The wind
pressure is 40 kg/cm2. Calculate the height of the conductor above ground
level at which it should be supported if a minimum clearance of 7m is to be
kept between the ground and the conductor. [10-24 m]
6. A transmission line has a span of 150 m between level supports. The
conductor has a cross-sectional area of 2 cm2. The ultimate strength is 5000
kg/cm2. The specific gravity of the material is 8.9 gm/cm3. If the wind
pressure is 1.5 kg/m length of the conductor, calculate the sag if factor of
safety is 5. [3.5 m]
