A steel tape is 100 m long at a temperature of 20°C and a pull of 10 kg. It was used to measure a distance of 624.95 m at a temperature of 32°C with an applied pull of 15 kg during measurement with the tape supported at both ends. The coefficient of thermal expansion is 0.0000116 m/ °C and a modulus of elasticity of 2x10° kg/cm. The weight of tape is 0.04 kg/m and a cross-sectional area of 0.06 cm. Compute for (a) sag correction (b) total corrections for tension, sag and temperature (c) corrected length of the line.
