Skid marks are divided into "acceleration marks" created on acceleration, if the engine provides more power than the tire can transmit; "braking marks", if the brakes "lock up" and cause the tire to slide; or "yaw marks", if the tire slides sideways. Each skid mark has a characteristic appearance, and an experienced accident reconstructor or ...
An automobile skid is an automobile handling condition where one or more tires are slipping relative to the road, and the overall handling of the vehicle has been affected. Subtypes of skid include: fishtailing, where the vehicle yaws back and forth across the direction of motion. spin or spinout where a vehicle rotates in one direction during ...
A yaw rate sensor that measures the rotation rate of the car. The data from the yaw sensor is compared with the data from the steering wheel angle sensor to determine regulating action. [47] A lateral acceleration sensor that measures the vehicle's lateral acceleration. This is often called an accelerometer. Wheel speed sensors that measure ...
In contrast to the T/S, the TC's gimbal is pitched up 30 degrees from the transverse axis. This causes the instrument to respond to roll as well as yaw [6] and allows the instrument to display a change more quickly as it will react to the change in roll before the aircraft has even begun to yaw. Although this instrument reacts to changes in the ...
An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the ...
The yaw string, also known as a slip string, is a simple device for indicating a slip or skid in an aircraft in flight. It performs the same function as the slip-skid indicator ball, but is more sensitive, and does not require the pilot to look down at the instrument panel. [ 1 ]
When performed in the snow, it is more often done to have fun than it is to make an earnest attempt at creating the circular skid mark pattern. [citation needed] In Australia, doughnuts performed in dust or mud are colloquially referred to as "circle work". Performing the doughnut maneuver can be hazardous.
In other words, This article should be called "Tire Marks", and then be divided skid marks, acceleration marks, and yaw marks. This is the naming convention used by accident reconstructions, and since that is the context in which this article seems to appear, it should probably be consistent with that.
