A line was recorded as 2500.00 meters long. The standard tape weighs 0.65 kg, 30.00m long at 20°C under a 50N pull. During the actual observation the temperature was 5°C and the tape was suspended under a 75N pull. It was also found that the tape is 3.00mm too short. If the line was inclined at 3%. E = 200GPa, A = 2.50mm² and the coefficient of linear expansion is 0.0000116 m/°C. (a) What is the actual inclined distance? (b) What is the actual horizontal distance.
