Hardy's statement that frictional force is largely adhesion, and to lesser extent, deformation energy is proved by simple experiment; actual contact surface of sliding contacts and hence friction per unit of contact surface was determined in several cases. English translation from Wissenschaftliche Veroeffentlichungen aus den Siemens-Werken v 17 n 4 1938 p 38-42.
