3. A line was found to be 2,850 m long when measured with a 50-m tape under a steady pull of 5.5 kg. at a mean temperature of 30°C. The tape was held in the air and supported at both ends and at every 15-m mark and 25-m mark in the tape. Determine the correct length of the line if the tape used is of standard length at 20°C under a pull of 6.5 kg. Assume the cross-sectional area of tape to be 0.025 cm², Elastic Modulus as 2.10 x 106 kg/cm², weighs 0.05 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.
