A steel section of the Alaskan pipeline had a length of 65 m and a temperature of 16°C when it was installed. What is its change in length when the temperature drops to a frigid -39°C?

do this the same way as the baseball bat

I did I multiply by the coefficent of steel which is 12*10^-6 and the chang e in temp. which is 16--39 got 55 but I'm getting the wrong answer.

• Physics -

delta L/L = alpha (-39 -16)
delta L/65 = 12*10^-6 * 55
delta L = 43900 * 10^-6 = .0439

Oh, remember it shrunk. It is -.0439
