Situation5. A line is recorded as 472.90 m. long. It is measured with a 0.65 kg. tape which is 30.005 m. long at 20°C under a 50 N pull supported at both ends. During measurement, the temperature is 5 °C and the tape is suspended under a 75 N pull. The line is measured on 3 % grade. Cross-sectional area of the tape is 3 mm^2. a. Compute the actual length of tape during measurement.
