A 100 m tape weighing 3 kg was standardized and found to be 0.02 m short at temperature of 10˚C and a 30 N pull when supported throughout. It was used to measure a distance which was recorded as 3245.68 m when the temperature was 15˚C and pull was 40 N supported only at quarter points. E = 200 GPa. Density of material is 7500 kg/cu.m, coefficient of thermal expansion = 11.6 x 10-6/˚C. Find the correct distance between the two points.
