    en.wikipedia.org/wiki/Centrifugal_switch

    A centrifugal switch is an electric switch that operates using the centrifugal force created from a rotating shaft, most commonly that of an electric motor or gasoline engine. The switch is designed to activate or de-activate as a function of the rotational speed of the shaft.

    en.wikipedia.org/wiki/High-G_training

    The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.

    en.wikipedia.org/wiki/Gravity_knife

    German Luftwaffe Fallschirmjäger-Messer or air force paratrooper knife. One of the most recognizable gravity knives is the World War II-era Flieger-Kappmesser (lit. ' flyer's cutting knife '), which utilizes a 4 in (10 cm) telescoping (OTF), gravity-propelled locking blade. First produced in 1937, the often so called Fallschirmjägermesser (lit.

  5. Governor (device) - Wikipedia

    en.wikipedia.org/wiki/Governor_(device)

    A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...

    en.wikipedia.org/wiki/Aircraft_engine_starting

    Cutaway view of an air-start motor of a General Electric J79 turbojet. With air-start systems, gas turbine engine compressor spools are rotated by the action of a large volume of compressed air acting directly on the compressor blades or driving the engine through a small, geared turbine motor. These motors can weigh up to 75% less than an ...

  7. Centrifugal force - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_force

    Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame.

  8. Artificial gravity - Wikipedia

    en.wikipedia.org/wiki/Artificial_gravity

    Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from ...

  9. Centrifugal governor - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_governor

    Centrifugal governors are used in many modern repeating watches to limit the speed of the striking train, so the repeater does not run too quickly. Another kind of centrifugal governor consists of a pair of masses on a spindle inside a cylinder, the masses or the cylinder being coated with pads, somewhat like a centrifugal clutch or a drum brake.
