WebRolling 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 … Webof the pavement, over curbs, and onto grass or dirt. A path involving differing drag factors can be managed using Combined Speed formula to determine the vehicle …
WebPrevious message: Paul Richardson: "Re: Seven Drag Factor Questions" Maybe in reply to: Raphael Martello: "grass coefficient of friction" Raphael, SAE 830612, "Friction Applications in Accident Reconstruction" lists dry grass as 0.5g.
