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 has supported by the ends under a pull of 10 kg. and

the observed mean temperature is 31 deg. celsius. The tape is of a 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 * 106kg / s * q . 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?
