A line was measured with a steel tape which was exactly 30m at 18°C and a pull of 50N and the measured length was 459.242m. Temperature during measurement was 28°C and the pull applied was 100N. The tape was uniformly supported during the measurement. Find the true length of the line of the cross-sectional area of the tape was 0.02 cm2, the coefficient of expansion per °C = 0.0000117 and the modulus of elasticity = 21 x 106N per cm2.
