A Civil Engineer used a 40m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevation between the initial point and the end point was found to be 1.25 m. The 40 m tape is of standard length at a temperature of 10°C and a pull of 50 N. During measurement the temperature reading was 9°C and the tape was supported at both ends with an applied pull of 45 N. The cross-sectional area of the tape is 6 mm2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.075 kg/m. Coefficient of thermal expansion is 0.0000116 /°C. 1. Determine the magnitude of the correction per tape length in meters due to temperature. Round off your answers to 4 decimal places. 2. Determine the magnitude of the correction per tape length in meters due to pull. Round off your answers to 4 decimal places. 3. Determine the magnitude of the correction per tape length in meters due to sag. Round off your answers to 4 decimal places. 4. What is the total correction per tape length due to temperature, pull and sag in meters? Round off your answers to 4 decimal places and include the negative sign if it is negative.

A line was found to be 2,395.25 m long when measured with a 30 m tape under a steady pull of 3 kg. at a mean temperature of 30°C. The tape was held in the air and supported at both ends and at every one third of the tape. Determine the correct length of the line if the tape used is of standard length at 20°C under a pull of 5 kg. Assume the cross-sectional area of tape to be 0.02 cm2, Elastic Modulus as 2.10 x 106kg/cm2, weighs 0.05 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.
