Abstract
A pendulum device is used to test the rolling resistance of a material. The device includes a rolling unit for contact with the material being tested, an assembly for initiating pendulum motion of the device, and measuring the amplitude of the pendulum motion over time. The rate of decrease of the amplitude of the pendulum motion is a measure of the rolling resistance of the material.
