| ~ philosophy | the rational investigation of questions about existence and knowledge and ethics. |
| ~ philosophical doctrine, philosophical theory | a doctrine accepted by adherents to a philosophy. |
n. (artifact) | 5. mechanism | device consisting of a piece of machinery; has moving parts that perform some function. |
| ~ action mechanism, action | the operating part that transmits power to a mechanism.; "the piano had a very stiff action" |
| ~ actuator | a mechanism that puts something into automatic action. |
| ~ robot, automaton, golem | a mechanism that can move automatically. |
| ~ axis of rotation, axis | the center around which something rotates. |
| ~ carriage | a machine part that carries something else. |
| ~ cartridge ejector, ejector | a mechanism in a firearm that ejects the empty shell case after firing. |
| ~ cartridge extractor, cartridge remover, extractor | a mechanism in a firearm that pulls an empty shell case out of the chamber and passes it to the ejector. |
| ~ clockwork | any mechanism of geared wheels that is driven by a coiled spring; resembles the works of a mechanical clock. |
| ~ controller, control | a mechanism that controls the operation of a machine.; "the speed controller on his turntable was not working properly"; "I turned the controls over to her" |
| ~ cooling, cooling system | a mechanism for keeping something cool.; "the cooling was overhead fans" |
| ~ delayed action | a mechanism that automatically delays the release of a camera shutter for a fixed period of time so that the photographer can appear in the picture. |
| ~ device | an instrumentality invented for a particular purpose.; "the device is small enough to wear on your wrist"; "a device intended to conserve water" |
| ~ drive | a mechanism by which force or power is transmitted in a machine.; "a variable speed drive permitted operation through a range of speeds" |
| ~ drive line, drive line system | mechanism that transmits power from the engine to the driving wheels of a motor vehicle. |
| ~ fail-safe | a mechanism capable of returning to a safe state in case there is a failure or malfunction. |
| ~ film advance | a mechanism for advancing film in a camera or projector. |
| ~ gear mechanism, gear | a mechanism for transmitting motion for some specific purpose (as the steering gear of a vehicle). |
| ~ homing device | the mechanism in a guided missile that guides it toward its objective. |
| ~ hydraulic system | a mechanism operated by the resistance offered or the pressure transmitted when a liquid is forced through a small opening or tube. |
| ~ ignition system, ignition | the mechanism that ignites the fuel in an internal-combustion engine. |
| ~ lock | a mechanism that detonates the charge of a gun. |
| ~ mechanical device | mechanism consisting of a device that works on mechanical principles. |
| ~ radiator | a mechanism consisting of a metal honeycomb through which hot fluids circulate; heat is transferred from the fluid through the honeycomb to the airstream that is created either by the motion of the vehicle or by a fan. |
| ~ rotating mechanism | a mechanism that rotates. |
| ~ steering linkage | mechanism consisting of a system of rods and levers connected to the front wheels of a motor vehicle; the steering gear pushes it left or right which swivels the front wheels, causing the vehicle to turn. |
| ~ steering mechanism, steering system | a mechanism by which something is steered (especially a motor vehicle). |
| ~ tape drive, tape transport, transport | a mechanism that transports magnetic tape across the read/write heads of a tape playback/recorder. |
| ~ whirler | a revolving mechanism. |
| ~ workings, works | the internal mechanism of a device. |
