A 50-m. tape was standardized and was found to be 0.0042 m. too long than the strength at an observed temperature of 580C and a pull of 15 kilos. The same tape was used to measure a certain distance and was recorded to be 673.92 m. long at an observed temperature of 680C and a pull of 15 kilos. Coefficient of linear expansion is 0.0000116 m/0C. A. Determine the standard temperature (T1) using 0.0042m as correction due to standard temp. B. Determine the total correction (in meter) due to temp. only. C. Determine the corrected distance/length of the line (in meter).

Give the following problem a try. If you get stuck, here is one way to work it: Essential Solution Video. An aluminum alloy [E = 70 GPa; v = 0.33; a = 23.0x10-6/°C] pipe is subjected to a tensile load P. The pipe has an outside diameter of D = 270 mm, a cross-sectional area of A = 7350 mm2, and a length of L = 10.0 m. The initial longitudinal normal strain in the pipe is zero. After load Pis applied and the temperature of the pipe has been increased by AT = 38°C, the longitudinal normal strain in the pipe is found to be 2395 µɛ. Calculate the magnitude of load P. L P Answer: P = i kN
