Diagram showing the path of a driver performing a U-turn.A vehicle with a smaller turning diameter will be able to perform a sharper U-turn. The turning radius (alternatively, turning diameter or turning circle) of a vehicle defines the minimum dimension (typically the radius or diameter) of available space required for that vehicle to make a semi-circular U-turn without skidding.
Examples of circular motion include: special satellite orbits around the Earth (circular orbits), a ceiling fan's blades rotating around a hub, a stone that is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a ...
Spinning event at night. Spinning is a South African motorsport that involves driving cars at speed in circles and performing stunts in and out of the car. It originated in Soweto in the late 1980s, and was performed as a funeral ritual in which a car was spun around to honor the deceased.
[citation needed] In Australia, doughnuts performed in dust or mud are colloquially referred to as "circle work". Performing the doughnut maneuver can be hazardous. Strain is placed on the vehicle's suspension and drivetrain, which may result in mechanical breakdown with loss of control.
The intention of Ackermann geometry is to avoid the need for tyres to slip sideways when following the path around a curve. [2] The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle.
In December 2024, a Waymo rider reportedly missed his plane after his self-driving rideshare car drove around in circles on his way to the Phoenix airport.
L.A. tech entrepreneur Mike Johns posted a video of his call to a customer service representative for Waymo to report that the car kept turning in circles.
Drivers race on the apron at Chicagoland Speedway (the area between the white and yellow lines). aero cover See wheel shroud. air jacks Pneumatic cylinders strategically mounted to the frame near the wheels of a racing car, which project downwards to lift the car off the ground during a pit stop to allow for quick tire changes or provide mechanics access to the underside of the car for repairs.
