The study showed that non-sprinters ran with an inefficient gait for the maximal speed trial while all groups ran with energetically efficient gaits for the distance trial. This indicates that the development of an economical distance running form is a natural process while sprinting is a learned technique that requires practice.
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.
Although rail vehicles occasionally do use drives without sensors, most need a rotary speed sensor for their regulator system. The most common type is a two-channel sensor that scans a toothed wheel on the motor shaft or gearbox which may be dedicated to this purpose or may be already present in the drive system.
Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder and servo) and wheel-speed sensors with ABS. The basic idea behind the need for a traction control system is the loss of road grip can compromise steering control and stability of vehicles.
Limitations of animal running speed provides an overview of how various factors determine the maximum running speed. Some terrestrial animals are built for achieving extremely high speeds, such as the cheetah, pronghorn, race horse and greyhound, while humans can train to achieve high sprint speeds. There is no single determinant of maximum ...
A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches.
