Answer to Question #174138 in Civil and Environmental Engineering for inA

Question

A 50 m steel tape was standardized and supported throughout its whole length and found to be 0.00205 m longer at an observed temperature of 31.80C and a pull of 8 kilos. This tape was used to measure a line that was found to be 662.702 m at average temperature of 24.60C using the same pull. What is the corrected length of the line and the standard temperature? Use the coefficient of expansion of 0.0000116 m per degree centigrade.

Answer 1

0.00205 m

31.80C and a pull of 8 kilos.

662.702 m at average temperature of 24.60C

coefficient of expansion of 0.0000116 m

0.00205 m × 50 m= 0.1025m

662.702 – 0.1025 = 662.5995m

662.5995 × 0.0000116

0.007686 C
