Friction and wear are measured on a tribometer, a machine that ensures the relative movement of two solid bodies under a normal force P, usually kept constant. Figure

shows a schematic diagram of the two types of contact commonly used:
plane/plane contact or contact between parts with conformal surfaces (figure

a ): the force P imposes an (apparent) contact pressure.
p = P /A
