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)

aeromechanics (s) (noun) (no pl)
The scientific study of air and other gases in motion or in equilibrium: Aeromechanics deals with the effect of solid bodies in the flow of the air and gases.

Aeromechanics also includes the two distinct branches of aerodynamics and aerostatics.

agricultural mechanics (pl) (noun)
The principles and use of mechanics for agricultural purposes; Agricultural mechanics deal with the development of agricultural equipment,including automated feed mixers.
backyard mechanic
Someone, whether qualified or not, who repairs his or her own vehicle or those of other people and does such work in his or her own yard or property.
biomechanical (adjective)
A reference to the applications of mechanical forces to living organisms and the investigations of the effects of the interactions of force and the body or system: "Biomechanical forces include those that come from within and outside the body."

"Biomechanical functions include the muscles, heart, lungs, and gravity on the skeletal structure."

1. The science concerned with the action of forces, internal or external, on the living body.
2. The study of the mechanical laws relating to the movement or structure of living organisms.
3. The study of body movements and of the forces acting on the musculoskeletal system.
4. The application of mechanics to the structures of living animals; especially, to the forces on the skeleton caused by the muscles, gravity, and resulting movements of the locomotor system.

Biomechanics is a curious blend of mechanical engineering and biology. It was born of the recognition that parts of a living organism may be viewed as mechanical devices to which engineering concepts; such as, fluid pressure, mechanical stress and friction can be applied.

New York Times, January 16, 1979.
A reference to the work of a dental technician.
electric firing mechanism
A firing mechanism which uses a firing magneto, battery, or alternating-current power in circuit with an electric primer.

One side of the line is connected by an insulated wire to the primer, and the other side is grounded to the frame of the weapon.

1. A reference to a mechanical device, system, or process that is actuated or controlled by electromagnetic or electrostatic phenomena.
2. Pertaining to a mechanical device, system, or process which is electrostatically or electromagnetically actuated or controlled.
3. Designating or of a mechanical device that is operated wholly or in part mechanically, but powered or controlled by electricity.
4. The use of electricity to run moving parts; for example, disk drives, printers and motors are examples of electromechanical devices.

Electromechanical systems must be designed for the eventual deterioration of moving components that wear over time.

electromechanical bell
A bell with a prewound spring-driven clapper which is tripped electrically to ring the bell.
electromechanical brake, electromechanical brakes
A brake whose force is obtained partly as a result of the attraction of two magnetized surfaces and partly by mechanical processes.
electromechanical breakdown
A mechanical runaway that occurs when the mechanical restoring force fails to balance the electrical compressive force.
electromechanical chopper, contact modulator (s) (noun); electromechanical choppers, contact modulators (pl)
A switch that is used to produce modified square waves having the same frequency as, and a definite phase relationship to, a driving sine wave or a waveform with deviation that can be graphically expressed as the sine curve or a form or shape of a wave (a ripple or undulation).

All electromagnetic radiation, including radio signals, light rays, x-rays, and cosmic rays, as well as sound, behave like rippling waves in the ocean.

electromechanical commutator
A commutator (an unidirectional current from a generator or a reversal of current into the coils of a motor) which in its simplest form has motor-driven rotating brushes to connect a number of data points in sequence to a common output line.
electromechanical device
A mechanical instrument which is operated by electricity.
electromechanical dialer
1. A device on a telephone that activates a group of precoded numbers when a user presses a designated button.
2. A telephone dialer that activates one of a set of desired numbers, coded into it in advance, when the user selects and presses a start button.
