From Wikipedia, the free encyclopedia. The results of these tests can be hard for the general public to obtain as manufacturers prefer to publicize "comfort" and "performance". Hysteresis is the main cause of energy loss associated with rolling resistance and is attributed to the viscoelastic characteristics of the rubber. Retrieved 7 February Two forms of this are hysteresis losses see below , and permanent plastic deformation of the object or the surface e. The coefficient of rolling resistance for a slow rigid wheel on a perfectly elastic surface, not adjusted for velocity, can be calculated by [1].

Rolling Resistance - Have you ever wondered what this is?

Such torques results in energy dissipation above that due to the basic rolling resistance of a freely rolling, non-driven, non-braked wheel. The weight of trains varies greatly; in some cases they may be much heavier per passenger or per net ton of freight than an automobile or truck, but in other cases they may be much lighter. This includes overcoming inertia Newton's Law , driveline friction, road grades, tire rolling resistance and air drag.
