A line was measured using a tape that is suspended with a pull of 145 N on both ends. The mean temperature during the measurement was 14°C. The whole length of the line was measured with 4 consecutive spans/segments. The tape was supported only at the ends of each segment when the measurement was done. The measured segments of the line are as follows: 29.988 m, 29.895 m, 29.838 m, and 29.910 m. Therefore the total length of the line measured was 119.631m. The tape was standardized with the following parameters: Standard pull = 95 N Standard temperature = 14°C Cross-sectional area = 3.35 mm^2 weight per length of the tape = 0.24525 N/m Coefficient of linear expansion = 0.9 x 10^-6 per °C %3D

A line was measured using a tape that is suspended with a pull of 145 N on both ends. The
mean temperature during the measurement was 14°C. The whole length of the line was
measured with 4 consecutive spans/segments. The tape was supported only at the ends of
each segment when the measurement was done.
The measured segments of the line are as follows: 29.988 m, 29.895 m, 29.838 m, and 29.910
m. Therefore the total length of the line measured was 119.631m.
The tape was standardized with the following parameters:
Standard pull
= 95 N
Standard temperature
= 14°C
Cross-sectional area
= 3.35 mm^2
weight per length of the tape = 0.24525 N/m
Coefficient of linear expansion = 0.9 x 10^-6 per °C
Young's modulus
= 14.8 x 10^4 MPa
