Question

A steel section of the Alaskan pipeline had a length of 65 m and a temperature of 15degree C when it was installed. What is its change in length when the temperature drops to a frigid -45degree C? A steel aircraft carrier is 374 m long when moving through the icy North Atlantic at a temperature of 1.6degree C. By how much does the carrier lengthen when it is traveling in the warm Mediterranean Sea at a temperature of 22degree C? m A commonly used method of fastening one part to another part is called "shrink fitting." A steel rod has a diameter of 2.0027 cm, and a flat plate contains a hole whose diameter is 2.0000 cm. The rod is cooled so that it just fits into the hole. When the rod warms up, the enormous thermal stress exerted by the plate holds the rod securely to

Explanation / Answer

change in length = l*alpha*change in temperature

change in length = 65*13*10^-6*(-45-15) = -0.0507 m

2) change in length = 374*13*10^-6*(22-1.6) = 0.099 m

l2 = 374+0.099 = 374.099 m
