Textbook Question
Chapter 9, Problem 70E
Historically, replacing dirt roads with paved roads reduced rolling friction between vehicles and the road surface. Replacing paved roads with steel rails reduced friction further. What will be the next step in reducing friction between vehicles and the surfaces over which they move? What friction will remain after surface friction has been eliminated?
