During the measurement in a catenary of a survey line of four bays the following information was obtained. Measured Length (m) BAY Temperature (degrees Celsius) Tension (N) Difference in elevation between ends (m) 35.699 18 187 +0.364 35.901 18.05 187 +0.274 3 35.982 18 187 0.432 4 35.955 17.95 187 +0.238 The tape has a mass of 0.032 kg/m and a cross sectional area of 3.92 mm^2. It was standardized in the flat at 20 degrees Celsius under a pull of 89 N. The coefficient of linear expansion for the material of the tape is 0.0000116/degrees Celsius and Young's modulus of 21x10^4 Mn/m^2. Determine the corrected length of the survey line in meters. Use 4 decimal places in your computation and final answer.

The tape has a mass of 0.032 kg/m and a cross sectional area of 3.92 mm^2. It was standardized
in the flat at 20 degrees Celsius under a pull of 89 N. The coefficient of linear expansion for the
material of the tape is 0.0000116/degrees Celsius and Young's modulus of 21x10^4 Mn/m^2.
Determine the corrected length of the survey line in meters. Use 4 decimal places in your
computation and final answer.
