Question

An aluminum wing on a plane is 37.1 m long when the temperature is 20 oC. At what temperature would the wing be 0.05 m shorter? Enter your answer to one decimal place and do not enter units for this problem. You should think about the physics of the situation before trying to solve the problem. (Hint: You are being asked for a temperature, not a temperature change). Round your answer to one decimal place and only enter the number, not the units for this problem.
Answer

Explanation / Answer

coefficient of linear expansion of Al = .000023 per degree Celsius change in length = L* .000023*change in temperature => -0.05 = 37.1* .000023*(T- 20) => T= -38.6 C
