10. TAPE MEASUREMENTS a. A line was recorded as 1750.00 meters long. It is measured with a 0.65 kg standard tape 30.00m long at 20°C under a 50N pull supported at both ends. During the measurement the temperature was 5°C and the tape was suspended under a 75N pull. It was also found that the tape is 3.0mm too short. The line was inclined on a 3% grade. What is the true inclined distance? E = 200GPa, A = 2.50mm² and the coefficient of linear expansion is 0.0000116 m/°C. b. A line was recorded as 2350.00 meters long. It is measured with a 0.65 kg standard tape 30.00m long at 20°C under a 50N pull supported at both ends. During the measurement the temperature was 5°C and the tape was suspended under a 75N pull. It was also found that the tape is 3.0mm too short. The line was inclined on a 3% grade. What is the true inclined distance?

10. TAPE MEASUREMENTS
a. A line was recorded as 1750.00 meters long. It is measured with a 0.65 kg standard tape
30.00m long at 20°C under a 50N pull supported at both ends. During the measurement
the temperature was 5°C and the tape was suspended under a 75N pull. It was also found
that the tape is 3.0mm too short. The line was inclined on a 3% grade. What is the true
inclined distance? E = 200GPa, A = 2.50mm² and the coefficient of linear expansion is
0.0000116 m/°C.
b. A line was recorded as 2350.00 meters long. It is measured with a 0.65 kg standard
tape 30.00m long at 20°C under a 50N pull supported at both ends. During the
measurement the temperature was 5°C and the tape was suspended under a 75N pull.
It was also found that the tape is 3.0mm too short. The line was inclined on a 3% grade.
What is the true inclined distance? E = 200GPa, A = 2.50 mm² and the coefficient of linear
expansion is 0.0000116 m/°C.
