    Scotch yoke – Mechanism to convert between rotational and reciprocating motion; Crank – Simple machine transferring motion to or from a rotating shaft at a distance from the centreline; Crankshaft – Mechanism for converting reciprocating motion to rotation; Swashplate – Mechanism to convert between reciprocating and rotary motion

  3. Scotch yoke - Wikipedia

    en.wikipedia.org/wiki/Scotch_yoke

    The Scotch yoke (also known as slotted link mechanism [1]) is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part.

  4. Reciprocal innervation - Wikipedia

    en.wikipedia.org/wiki/Reciprocal_innervation

    Reciprocal innervation describes skeletal muscles as existing in antagonistic pairs, with contraction of one muscle producing forces opposite to those generated by contraction of the other. For example, in the human arm, the triceps acts to extend the lower arm outward while the biceps acts to flex the lower arm inward. To reach optimum ...

  5. Reciprocal inhibition - Wikipedia

    en.wikipedia.org/wiki/Reciprocal_inhibition

    Reciprocal inhibition is a neuromuscular process in which muscles on one side of a joint relax to allow the contraction of muscles on the opposite side, enabling smooth and coordinated movement. [1] This concept, introduced by Charles Sherrington , a pioneering neuroscientist , is also referred to as reflexive antagonism in some allied health ...

  6. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    For example, exercises that are performed at maximum rates for between 1 and 3 minutes depend heavily upon the lactic acid system. [1] In activities such as running 1500 meters or a mile, the lactic acid system is used predominantly for the "kick" at the end of the race.

  7. Mechanical impedance - Wikipedia

    en.wikipedia.org/wiki/Mechanical_impedance

    Examples of potentials are: force, sound pressure, voltage, temperature. Examples of flows are: velocity, volume velocity, current, heat flow. Impedance is the reciprocal of mobility. If the potential and flow quantities are measured at the same point then impedance is referred as driving point impedance; otherwise, transfer impedance.

    This movement is slightly more advanced than some other desk exercises, but it will certainly get your blood flowing. "It strengthens muscles and bones in the front and back upper body, core, and ...

  9. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
