Abstract
Coefficient of friction is defined as the ratio of the force of friction to the load producing it. The accepted laws of the coefficient of friction are: 1. It is independent of the area of the surface in contact. 2. It is independent of the load applied. 3. It is independent of the velocity, at low values. 4. The static value is greater than the kinetic, i. e., it is greater at the beginning of motion than after motion has been established. The accompanying data will show that every one of these accepted laws are violated by rubber. The following values for area were obtained by varying the pressure in an automobile tire in place on an automobile on concrete.Keywords
