A 100 meter steel tape is used to measure the distance of the line and found to be 1539.28 meter long. During measurement, the tape supported the ends under a pull of 10 kg and the observed mean temperature is 31 degrees celsius. The tape is of standard temperature of 20 degrees celsius and a tension of 12 kg. The cross sectional area of the tape is 0.035 sq. cm. The coefficient of linear expansion is 2.0 x 10^6 kg/sq.cm. The tape weighs 1.5 kg.
