Mechanics: Friction in a spin

Thomas C. Halsey

Top

The mechanics of friction may seem the stuff of high-school physics, but only now are some aspects of the problem being understood. A spinning coin is the subject of a new exploration of frictional forces.

One of the most unlikely revivals of our time is that of the science of mechanics. The first great era of classical mechanics culminated in the work of Joseph-Louis Lagrange (1736–1813) and William Hamilton (1788–1856).
