A line was found to be 2,395.25 m long when measured with a 30 m tape under a steady pull of 3 kg. at a mean temperature of 30°C. The tape was held in the air and supported at both ends and at every one third of the tape. Determine the correct length of the line if the tape used is of standard length at 20°C under a pull of 5 kg. Assume the cross-sectional area of tape to be 0.02 cm2, Elastic Modulus as 2.10 x 106kg/cm2, weighs 0.05 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.
