Mechanism may refer to:
- Mechanism (biology) In biology, a mechanism is part of an answer to a question about why some object or process occurred. Thus mechanism refers back from the object or process, along some chain of causation. No description of mechanism is ever complete. For example, the mechanism of sunlight might include the rotation of the earth, the Earth's orbit, the sun, nuclear, explaining how a feature is created
- Mechanism (chemistry) In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs, explaining a reaction pathway
- Mechanism (philosophy) In philosophy, mechanism is the theory that all natural phenomena can be explained by laws of nature. It's the opposite of vitalism, which claims organisms have "vital forces" which aren't physical, a theory that all natural phenomena can be explained by physical causes
- Mechanism (sociology) In sociology a mechanism is a set of rules designed to bring about a certain outcome through the interaction of a number of agents.[original research?], a set of rules designed to bring about a certain outcome
- Mechanism (technology) A mechanism is some technical aspect of a larger process or mechanical device, or combination of parts designed to perform a particular function. Sometimes an entire machine may be referred to as a mechanism. Examples are the steering mechanism in a car, or the winding mechanism of a wristwatch. When one of the links of a kinematic chain is fixed,, a device of which a mechanical joint is used
- Mechanism (engineering) A mechanism is a combination of resistant bodies, so interconnected that by applying force or motion to one or more of those bodies, some of those bodies are caused to perform desired work accompanied by desired motions. The connections present in a mechanism are called kinematic pairs. Kinematic pairs can be classified as higher pair or lower, rigid bodies connected by joints in order to accomplish a desired force and/or motion transmission

- Machine A machine is any device that uses energy to perform some activity. In common usage, the meaning is that of a device having parts that perform or assist in performing any type of work. A simple machine is a device that transforms the direction or magnitude of a force without consuming any energy. The word "machine" is derived from the
- Mechanism design Mechanism design is a field in game theory studying solution concepts for a class of private information games. The distinguishing features of these games are:, the art of designing rules of a game to achieve a specific outcome
- Mechanism of action In pharmacology, the term mechanism of action refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor, the means by which a drug exerts its biological effects
- Defence mechanism In Freudian psychoanalytic theory, defence mechanisms or defense mechanisms are unconscious psychological strategies brought into play by various entities to cope with reality and to maintain self-image. Healthy persons normally use different defences throughout life. An ego defence mechanism becomes pathological only when its persistent use leads, unconscious mechanisms aimed at reducing anxiety
- Reaction mechanism In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs, the sequence of reactions by which overall chemical change occurs
- Antikythera mechanism The Antikythera mechanism , is an ancient mechanical calculator (also described as the first known mechanical computer) designed to calculate astronomical positions. It was recovered in 1900–01 from the Antikythera wreck, but its complexity and significance were not understood until decades later. It is now thought to have been built about 150–, an ancient Greek analog computer An analog computer is a form of computer that uses the continuously-changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities incrementally, as their numerical values change
