It was used to measure a distance which was recorded as 2,650.25 meters when temperature was 15°C and the pull was 40N supported only at quarter points. The elastic modulus of the material is given by E=200 GPa, density of the material is 7,500 kg/cubic meter and the coefficient of thermal expansion = 11.6x10-6 /°C. Find the correct distance between the two points.
