SLIPPERY SURFACES: TRAJECTORY WHEN FRICTION IS NULL

For road vehicles, motion without adhesion is a rather uncommon and exceptional condition, but it is very significant with regard to safety of circulation. If on the one hand it is very important to know the reasons for the loss of an effective connection between wheel and road, on the other hand it seems interesting to determine the trajectory of a vehicle during absence of adhesion, in order to foresee where it is possible to recover a part of transverse force, enough to restore driving. The author assimilates the vehicle to a massive material point, having a not null initial speed, and he determines its trajectory on condition of belonging to roadway. In all the possible instances of straight stretch with uniform or variable transversal slope, of circular curve with uniform or variable transversal slope, and finally of transition curves, analytic developments and graphic representations of calculation results are shown.
