A line was determined to be 2,682.13 meters when measured with a 20 m. steel tape supported throughout its length under a pull of 4 kg. at a mean temperature of 39 °C. Tape used is of standard length of 19 °C under a pull of 5 kg. Cross- sectional area of the tape is 4.796 mm^2. Determine the TOTAL ERROR of the LINE due to TEMPERATURE in meters. Round off to three decimal places. Input the magnitude only.
A 50 m tape of standard length has weight of 0.05 kg/m, cross section is 0.04sq cm, E is 2.10 x10 6 kg/sq cm. The tape is of standard length under a pull of 5.5 kg when supported throught its length.
