An engineer used a 30 m tape in measuring an inclined ground 459.20 m long. The difference between the starting point and end point is 1.20 m. The tape is of standard length at a temperature of 100 C and a pull of 50 N. During measurement the temperature reading was 15 0 C and a pull of 75N applied at both ends. A= 6.5mm2 ; E = 200GPa; K = 0.0000116 m/C0 . The mass of the tape is 0.075kg/m. Determine the horizontal distance.
