A line is recorded as 472.90 m long. It is measured with a 0.65 kg tape which is 30.005 m long at 20 °C under a 50 N pull supported at both ends. During measurement, the temperature is 5 °C and the tape is suspended under a 75 N pull. The line is measured on 3% grade. E = 200 GPa, cross-sectional area of tape is 3 mm2 and the coefficient of linear expansion is 0.0000116 /°C. Compute: a. The actual length of tape during measurement. b.The total error to be corrected for the inclined distance c.The true horizontal distance

Question
A line is recorded as 472.90 m long. It is measured with a
0.65 kg tape which is 30.005 m long at 20 °C under a 50
N pull supported at both ends. During measurement, the
temperature is 5 °C and the tape is suspended under a 75
N pull. The line is measured on 3% grade. E = 200 GPa,
cross-sectional area of tape is 3 mm2 and the coefficient
of linear expansion is 0.0000116 /°C. Compute:
a. The actual length of tape during measurement.
b.The total error to be corrected for the inclined distance
c.The true horizontal distance
