A 30 m. steel tape weighing 1.45 kg is of standard length under a pull of 5 kg supported for a full length. The tape was used in measuring a line 985.55 m long on a smooth level ground under a steady pull of 10 kg. mm Assuming E= 2 x 10^6kg/cm and the unit weight of steel (y) to be 7.9 x 10^-3 kg/cm^3. Use A = W / (L * y) for the cross sectional arca of the steel tape. a.)Determine the correction for increase in tension and; 2.) the correct length of the line measured.
