89 N has cross-sectional to an accuracy of ± area of 6 mm² and a mass of 2.32 kg. It is to be used to measure lengths A steel tape 50 m long on the flat at 20°C under a pull of 1 10000 when supported at mid span. Assume that the ends of the tape and mid span support are the same level and the field temperature is 20°C. Determine the change in tension to be applied to ensure that an error greater than + 5 mm will not occur when measuring the length 50 m. Take Young's modulus to be 207 kN/mm² and g to be 9.81 m/s²
