Prob 2. (15pts) A line was found to be (2865.35+y)m long when measured with a 30-m tape under a steady pull of (6.5+y) kg at a mean temperature of 300c. Determine the correct length of the line if the tape used is of standard length at 200c under a pull of 5.5kg. Assume the cross-sectional area of tape to be 0.025cm2, elastic modulus as 2.10 x 106 kg/cm2, and coefficient of thermal expansion to be 0.0000116/@c.

Question
Prob 2. (15pts) A line was found to be (2865.35+y)m long when measured
with a 30-m tape under a steady pull of (6.5+y) kg at a mean temperature
of 300C. Determine the correct length of the line if the tape used is of
standard length at 200c under a pull of 5.5kg. Assume the cross-sectional
area of tape to be 0.025cm2, elastic modulus as 2.10 x 106 kg/cm2, and
coefficient of thermal expansion to be 0.0000116/ec.
