Different geometry at skis for backcountry skiing (top), allmountain skis and piste skis for carve turns.. Ski geometry is the shape of the ski.Described in the direction of travel, the front of the ski, typically pointed or rounded, is the tip, the middle is the waist and the rear is the tail.
The stunt is generally performed by driving one pair of wheels up on a ramp to lift one side of the car. [2] Alternately, the stunt can be done in a vehicle with a high center of gravity (such as a 4x4 or SUV) by turning sharply or at speed. This technique is more dangerous because there is a strong possibility of the vehicle tipping completely ...
Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
The tire model must produce realistic shear forces during braking, acceleration, cornering, and combinations, on a range of surface conditions. Many models are in use. Most are semi-empirical, such as the Pacejka Magic Formula model. Racing car games or simulators are also a form of vehicle dynamics simulation. In early versions many ...
A carved turn is a skiing and snowboarding term for the technique of turning by shifting the ski or snowboard onto its edges. When edged, the sidecut geometry causes the ski (in the following, snowboard is implicit and not mentioned) to bend into an arc, and the ski naturally follows this arc shape to produce a turning motion.
Zero scrub radius (top) positive scrub radius (center) negative scrub radius (bottom) In an automobile's suspension system, the scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road. It can be positive, negative or zero.
However, due to the weight transfer inherent while turning, the outside wheels bear more of the force of turning and negative camber will improve handling overall. Caster angle will also compensate for this to a degree, as the top of the outside tire will tilt slightly inward, and the inner tire will respectively tilt outward. However, any ...
In aeronautics, the roll moment is the product of an aerodynamic force and the distance between where it is applied and the aircraft's center of mass that tends to cause the aircraft to rotate about its roll axis. The roll axis is usually defined as the longitudinal axis, which runs from the nose to the tail of the aircraft.
