A 50 m tape of standard length has a weight of 0.05 kg/m, with a cross b) sectional area of 0.04 cm2. The tape is of standard length under the pull of 5.5 kg when supported throughout its length at 20°C. The tape measured the distance between point A and B as 458.65 m. At the time of measurement, the pull applied was 8 kg with the tape supported only at its end points and the temperature was observed at 18°C. Based on the information given, identify the errors that are involved and calculate these errors. Then, calculate the corrected length of the line. E = 2.10 x 107 kg/cm2 C = 1.16 x 10-5 m/°C

Transcribed Image Text:A 50 m tape of standard length has a weight of 0.05 kg/m, with a cross
b)
sectional area of 0.04 cm2. The tape is of standard length under the pull of
5.5 kg when supported throughout its length at 20°C. The tape measured
the distance between point A and B as 458.65 m. At the time of
measurement, the pull applied was 8 kg with the tape supported only at its
end points and the temperature was observed at 18°C. Based on the
information given, identify the errors that are involved and calculate these
errors. Then, calculate the corrected length of the line.
E = 2.10 x 107 kg/cm2
C = 1.16 x 10-5 m/°C
