Question

A base line was measured with a steel tape, which was exactly 30 m at 20°C, and a pull of 6 kg and the measured length was 459.242 m. Temperature during measurement was 30°C and the pull applied was 10 kg. The tape was uniformly supported during the measurement. Find the true length of the line if the cross-sectional area of the tape was 0.02 m cm2 the coefficient of expansion per 1°C = 0.0000035, and the modulus of elasticity = 2.1 ×106 kg/cm2​
