Steve Roger measured a line and found it out to be 950 m long using a 20 – m tape under a steady pull of 4 kg at a mean temperature of 25°C. The tape was held in the air and supported at both ends and at the center. Determine the correct length of the line if the tape used is of standard length at 22°C under a pull of 6 kg. Assume the cross-sectional area of tape to be 0.05 cm2, modulus of elasticity as 2.10 x 10^6 kg/cm^2, weighs 0.08 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.
