A 50 m tape weighing O.049 kg/m with'a cross-sectional area of O.05 sq. cm and modulus of elasticity equal to 2x106 kg/cm2 is used in determining the distances between two points. The tape is of standard length under a pull of 6.70 kg and a temperature of 25°C when supported throughout its entire length. The tape was then used in the field to measure a distance that was determined to be 378.123 m. At the time the measurement was made, the constant pull applied was 9 kg with the tape supported only at endpoints. During the measurement the recorded temperature was 17°C. Use a=11.6x10-6/°C. Determine the correct length (in feet)of the line.
