A line is recorded as 472.60 m long. It is measured with a 0.68 kg. tape which is 30.002 m long at 20 degrees Celsius under a 4.45 kg. pull, supported throughout its length. During measurement, the temperature is 4.44 degrees Celsius and the tape is suspended under a 6.80 kg. pull. Assume E=1.97x10E6 kg/sq. cm., cross-sectional area of tape is 0.0284 sq. cm., and coefficient of linear expansion is 0.0000116/degree Celsius.
