Imagine a 40,000-km steel pipe that forms a ring to fit
Chapter 7, Problem 41TAS(choose chapter or problem)
Imagine a \(40,000-km\) steel pipe that forms a ring to fit snugly entirely around the circumference of Earth. Suppose that people along its length breathe on it so as to raise its temperature by \(1^{\circ} \mathrm{C}\). The pipe gets longer—and is also no longer snug. How high does it stand above ground level? Show that the answer is an astounding \(70 \ m\) higher! (To simplify, consider only the expansion of its radial distance from the center of Earth, and apply the geometry formula that relates circumference \(C\) and radius \(r: C=2 \pi r\).)
