Finding the coefficient of rolling friction (CRF) by the inclined plane method is similar to the manner used in establishing the coefficient of sliding friction. For the rolling case, the difficulty arises from the fact that the usual devices employed in angular measurements present errors greater than the effective angle. The paper surmounts this inconvenient by obliging the body to roll along a well controlled direction different from the steepest line of the plane. The experimental values found for the coefficient of rolling friction are in good agreement with the ones from literature.
