  2. Mechanical amplifier - Wikipedia

    en.wikipedia.org/wiki/Mechanical_amplifier

    A mechanical amplifier or a mechanical amplifying element is a linkage mechanism that amplifies the magnitude of mechanical quantities such as force, displacement, velocity, acceleration and torque in linear and rotational systems. [1]

  3. Linear amplifier - Wikipedia

    en.wikipedia.org/wiki/Linear_amplifier

    A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .

  4. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration). The motion of a particle (a point-like object) along a line can be described by its position x {\displaystyle x} , which varies with t {\displaystyle t} (time).

  5. Straight-line mechanism - Wikipedia

    en.wikipedia.org/wiki/Straight-line_mechanism

    A straight-line mechanism is a mechanism that converts any type of rotary or angular motion to perfect or near-perfect straight-line motion, or vice versa. Straight-line motion is linear motion of definite length or "stroke", every forward stroke being followed by a return stroke, giving reciprocating motion.

  6. Linear actuator - Wikipedia

    en.wikipedia.org/wiki/Linear_actuator

    A linear actuator is an actuator that creates linear motion (i.e., in a straight line), in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers , and in many other places where linear ...

  7. Chebyshev linkage - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_linkage

    The motion of the linkage can be constrained to an input angle that may be changed through velocities, forces, etc. The input angles can be either link L 2 with the horizontal or link L 4 with the horizontal. Regardless of the input angle, it is possible to compute the motion of two end-points for link L 3 that we will name A and B, and the ...

  8. Bellcrank - Wikipedia

    en.wikipedia.org/wiki/Bellcrank

    Many applications do not change the direction of motion but instead amplify a force "in line", which a bellcrank can do in a limited space. There is a tradeoff between range of motion, linearity of motion, and size. The greater the angle traversed by the crank, the more the motion ratio changes, and the more non-linear the motion becomes.

  9. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    Linear motionmotion that follows a straight linear path, and whose displacement is exactly the same as its trajectory. [Also known as rectilinear motion] Reciprocal motion; Brownian motion – the random movement of very small particles; Circular motion; Rotatory motion – a motion about a fixed point. (e.g. Ferris wheel).
