A 100m tape is of standard length at a temperature of 20°C and a pull of 50N. It was used to measure a distance of 3768.92m. During measurement, the temperature reading was 29°C and the tape was supported at both end with an applied pull of 85N. The cross-sectional area of the tape is 2.8mm 2, the unit weight is 0.13N/m, themodulus of elasticity is 200GPa and the coefficient of linear expansion is 0.0000116/°C. Determine: a. the total temperature correction b. the total pull correction c. the total sag correction
