A 30-m steel tape weighing 1.75 kg is of standard length under a pull of 4.55 kg, supported for full length. This tape was used in measuring a line (found to be 1371.50 m) on smooth level ground under a steady pull of 8 kg. Assuming E = 2.05 x 10° kg/cm2 and that the unit weight of steel is 7.9 x 10 kg/cm?, determine the following: cross-sectional area of the tape correction for increase in tension for the whole tape length measured and the correct length of the measured line.

Transcribed Image Text:2. A 30-m steel tape weighing 1.75 kg is of standard length under a pull of 4.55 kg, supported for full
length. This tape was used in measuring a line (found to be 1371.50 m) on smooth level ground under
a steady pull of 8 kg. Assuming E = 2.05 x 10° kg/cm? and that the unit weight of steel is 7.9 x 10
kg/cm, determine the following: cross-sectional area of the tape
correction for increase in
tension for the whole tape length measured
and the correct length of the measured line.
