The force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction.. The rolling resistance can be expressed as. F r = c W (1). where .

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface.It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc. is recovered when the pressure is removed. Two forms of this are hysteresis losses (see ...

A hollow crushing roll has an axial inner chamber that has an axis of symmetry (O). The crushing roll is a driven member that has an outside surface which forms a crushing zone between it and the reaction surface of the jaw assembly. Positioned at least partially within the crushing roll, an eccentric shaft serves as a driving member.
