Exercise 2.1 A 100- m steel tape is used to measure the distance of the line and found to be 1539.28 m long. During measurement, the tape is supported the ends under a pull of 10 kg and the observed mean temperature is 31 deg. celsius. The tape is of standard temperature of 20 deg. celsius and a tension of 12 kg. The cross sectional area of the tape is 0.035 sq. cm. The coefficient of linear expansion is 0.0000116/ deg. celsius and the modulus of elasticity of steel is 2.0 x 106 kg/ sq. cm. The tape weighs 1.5kg. a) Determine the total correction for temperature. b) Determine the total correction due to sag. c) What is the correct length of the line?
