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. Coefficient of thermal expansion is 0.0000116/°C and a modulus of elasticity of 2x106kg/cm2. Weight of tape is 0.04 kg/m and a cross sectional area of 0.06 cm2. a) Compute the sag correction. b) Compute the total correction for tension, sag and temperature.c) Compute the corrected length of the line by applying the combined corrections for tension, sag and temperature
