mechano-, mechan-; mechanico-; machin-
(Greek makhana, machana > Latin machina: machine, device, tool; an apparatus for applying mechanical power to do work; mekhanikos > machynen, decide a course of action, contrive, plot contrivance; a machine or the workings of machines)
2. A division of engineering concerned with the efficient design, operation, and maintenance of machines: "Mechanical engineering involves the design, the production, and the use of machinery and tools, as well as the generation and transmission of heat and mechanical power."
2. The amount of mechanical energy equivalent to a unit of heat.
3. The number of units of work or energy equal to one unit of heat; such as, 4.1858 joules, which equals one small calorie.
2. A property which involves a relationship between stress and strain or a reaction to an applied force.
2. The removal of heat by utilizing a refrigerant subjected to cycles of refrigerating thermodynamics and employing a mechanical compressor.
2. A mechanical styptic which assists the clotting of blood by mechanical means.
2. A collective term for all of the natural physical processes which break rock into smaller fragments without chemical changes; for example, wind, abrasions, temperature changes, frost actions, and biological effects; such as, plant root extensions or animal burrowing.
2. A completed assembly of artwork and copy: "The mechanicals are normally mounted on a sheet of stiff paper."
"Mechanics deals with motion and with the reaction of physical systems with internal and external forces which produce movements."
"The field of mechanics is subdivided into statics and dynamics; depending on the types of systems and phenomena that are involved."
- Dynamics is usually subdivided into kinematics (motion without reference to force or mass) and kinetics (forces that cause motions of bodies).
- Statics deals with bodies at rest.
3. The procedure involved when something is done or used: "Jerry was receiving instructions regarding the mechanics of his musical instrument."
2. A piece of machinery or a part or group of parts that have a particular function: "A can-opener is a simple mechanism used to open cans."
"Cameras have had shutter mechanisms that were used to take good pictures."3. A system or process which is used to produce a particular result: "The legislature is still trying to come up with a legal mechanism to prevent lobbyists from having too much influence on government decisions."
4. Procedures for thinking or behaving that help or protect people in specific ways: "Local officials are making efforts to provide mechanisms that can help people who are suffering from the terrible results of the tornadoes that destroyed homes and seriously injured or killed family members."
