Historically, magnetic sensor systems cost more than optical systems, but this difference is narrowing rapidly. Magnetic Hall and magnetoresistive sensor systems can be imbedded in plastic or potting material, which increases mechanical reliability and eliminates damage from water and grease. Wheel speed sensors can also include hysteresis ...
Sprint cars do not utilize a transmission but have an in-or-out gearbox and quick-change rear differentials for occasional gearing changes. As a result, they do not have electric starters (or even electrical systems other than a ignition magneto) and require a push to be started. The safety record of sprint car racing in recent years has been ...
The second half of the test involved subjects performing a 100-m sprint on a man-made track using radar to measure the forward speed of runners to create velocity-time curves. The main result of this study showed that the force application technique (rather than simply the total amount of force applied) is the key determinant factor in ...
A pressure sensor will detect an early start and the loudspeakers provide the runners with the sound from the starter all at the same time. Starting blocks are a device used in the sport of track and field by sprint athletes to brace their feet against at the start of a race so they do not slip as they stride forward at the sound of the starter ...
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent.
