Answer to Question #193130 in Physics for Emerso

Question

. A line is recorded as 475.25 m long. It is measured with a 6.5 N tape which is 30.492 m long at 68⁰F under a 10 lb. pull supported at end points. During measurement the temperature is 4.5⁰C and the tape is suspended under a 71 N pull. The line is measured on 3% grade. What is the true horizontal distance? Modulus of elasticity of the tape is 1.93 X 10⁸ KPa and cross-sectional area of tape is 0.0284 cm². Coefficient of expansion of the tape material is 0.0000116 m/⁰C.
