: A line recorded as 472.90 m long. It is measured with a 0.65 kg tape ( 30m ) which is 30.005 m long at 68° F under a 5.0968 kg pull support at both ends. During measurement the temperature is 41° F and the tape is suspended under a 75N pull. The line is measured on 4% grade. E = 200 GPa, Cross-sectional area of tape is 3mm?. Hint: K=0.00000645 ATIF a. Compute the actual length of the tape during the measurement. ( 10 points) b. Compute the total error to be corrected for the inclined distance ( 5 points ) c. What is the true horizontal distance. 10 points)
