2. A 30-m steel tape weighing 1.45 kg is of standard length under a pull length. The tape was used in measuring a line 938.55m long on a smooth level ground under a steady pull of 10 kg. Assuming E = 2x10° kg/cm² and the unit weight of steel to be 7.9x10° kg/cm?. a. Determine the cross-sectional area of the tape in cm?. 5 kg. supported b. Determine the correction for increase in tension. c. Determine the correct length of the line measured.
