A line was determined to be 2395.25m when measured with a 30-m steel tape supported throughout its length under a pull of 4kg at a mean temperature of 35 degree celcius. Tape used is of standard length at 20 degree celcius under a pull of 5kg. Cross-sectional area of the tape is 0.03 cm squared. Coefficient of thermal expansion is 0.0000116/ degree celcius. Modulus of elasticity of tape is 2x106kg/cm squared. a. Determine the error of the tape due to change in temperature. b. Determine the error due to tension c. Determine the corrected length of the line.
