mechanism where an arm attached to a rotating shaft by which circular motion is imparted to the shaft

in analytical mechanics, the work of a force on a particle along a virtual displacement

assembly of bodies connected to manage forces and movement

Mechanism to convert between rotational and reciprocating motion

mechanical linkage that converts rotary motion to approximately-straight motion, invented by James Watt

mechanical linkage capable of transforming rotary motion into linear motion

six-bar straight-line mechanism

four-bar straight-line mechanism

thumb|Swashplate animation. The rotating shaft and plate are shown in silver. The fixed plate is shown in gold and six shafts each take a reciprocating motion from points on the gold plate. The shafts might be connected to pistons in cylinders. Note the power may be coming from the shaft to drive the pistons as in a pump, or from the pistons to drive the shaft rotation as in an engine

Type of gear used in early beam engines

structure that resembles a geodesic dome

four-bar straight-line mechanism

joins a piston to the crosshead and thus to the connecting rod that drives the crankshaft or the driving wheels

mechanisms generating real or approximate straight line motion

mechanisms that provide a perfect straight line motion without sliding guides

planar mechanism designed to simulate the gait of legged animals
