Friction

Synopsis
Opens with simple laboratory demonstrations of the classical laws of friction, followed by an examination of actual surfaces using taper sections under the electron microscope. Large scale models of surfaces show how small the real areas of contact are. Deals also with problems of reducing friction by fluid film lubrication and introduces the idea of the boundary layer.
