(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)

electromechanical energy
Energy which is present in an induction coil or solenoid.
electromechanical frequency meter
A meter that uses the resonant properties of mechanical devices to indicate frequency.
electromechanical plotter, digital plotter, plotter, incremental plotter
1. Specifically, an output device that produces graphic or pictorial representations of computer data on a hard copy by drawing with one or more automatically controlled pens that move in small steps as used with digital computers.
2. An automatic device used in conjunction with a digital computer to produce a graphic or pictorial representation of computer data on a hard copy.
3. A graphics printer that draws images with ink pens.

It draws point-to-point lines directly from vector graphics files.

The plotter was the first computer output device that could print graphics as well as accommodate full-size engineering and architectural drawings.

electromechanical recorder
A device that transforms electrical signals into equivalent mechanical motion which is transferred to a medium by cutting, embossing, or writing.
electromechanical recording
1. A document created by varying the signal of electric current flowing through a stylus moving across a sheet of paper.
2. Recording by means of a signal-actuated mechanical device; such as, a pen arm or mirror attached to the moving coil of a galvanometer.
3. A tool that transforms electrical signals into equivalent mechanical motion which is transferred to a medium by cutting, embossing, or writing.
electromechanical relay
1. A device consisting of a coil and an armature that moves under the influence of a magnetic field produced by the coil to close or to open a contacting switch.
2. A protective relay operating on the principle of electromagnetic attraction; such as, a plunger relay or of electromagnetic induction.
electromechanical timer
Usually refers to a motor-driven timer, with or without an electrically operated clutch.

It can also apply to pneumatic and thermal timers, or to slow pull-in or drop-out relays.

electromechanical transducer (s) (noun), electromechanical transducers (pl)
1. An instrument that converts mechanical energy into electrical energy or a reverse process.
2. A transducer (electrical device that converts one form of energy into another) for receiving waves from an electric system and delivering waves to a mechanical system, or the reverse.
electromechanical transduction (s) (noun), electromechanical transductions (pl)
A variation of electromagnetic transduction.

In electromagnetic devices, it is often difficult to control the spatial relationship of the magnet and coil.

Because the magnet is attached to one portion of the anatomy and the coil attached to another part, the patient may observe a wide variation in performance.

As the relationship between the coil and the magnet changes, it results in a variance of the frequency response and a significant fluctuation of output levels.

An electromechanical device has an energizing coil and a magnet that are housed within an assembly which optimizes spatial and geometric relationships in order to avoid variability.

The electromechanical transducer directly connects to the ossicular chain (any of certain small bones, as those of the middle ear) to transmit the mechanical energy that is produced.

1. The science and technology of electromechanical devices, systems, or processes.
2. The technology of mechanical devices, systems, or processes which are electrostatically or electromagnetically actuated or controlled.
3. The branch of electrical engineering concerned with machines producing or operated by electric currents.
fluid mechanics
1. The scientific study of the mechanical properties of fluids (gases and liquids) in motion or at rest, including the observation, description, and mathematical computation of the behavior of fluids.
2. The experimental and mathematical-computational study of the mechanical behavior of fluids.

Fluid mechanics includes the transfer of heat and matter resulting from motion of the fluid, and the driving of the fluid motion due to differences in density which may be induced by temperature, as well as the effects due to temperature dependency of the constants of materials; for example, the viscosity.

3. The study of fluids and gases at rest and in motion which can be divided into hydrostatics, the behavior of liquids at rest; hydrodynamics, the behavior of liquids in motion; and aerodynamics, the behavior of gases in motion.

Hydrostatics takes into account the forces exerted by a liquid in all directions, not just the downward gravitational pull; such as, the upward force exerted on a submerged object that causes bouyancy.

Hydrodynamics is the study of fluid flow and fluid friction, or viscosity.

Aerodynamics is the study of the motion of gases which is most often applied to the study of air and the motion of solid bodies in it.

—Excerpts from "Fluid Mechanics", Encyclopedia of Science and Technology;
Routledge; New York; 2001; page 200.
1. The study of the mechanics of fluids or the laws of equilibrium and motion concerning fluids.
2. The area of fluid dynamics that is concerned with the study of liquids.
The same thing as iatrophysics or a 17th-century school of medicine that attempted to explain life and physiological processes using the knowledge of physics (the science of nature, or of natural objects) which was known at that time.
machinability (s), machinabilities (pl) (nouns)
The ease with which it is possible for a metal to be machined to a desired surface finish: "Any materials that have good machinabilities don't need as much power to cut and can be quickly cut, and have a good finish without any significant wearing of the tooling."
machinable (adjective)
1. Materials that are capable of being cut or shaped with machine tools: "The industrial producers were able to make significant products with the machinable plastics and aluminum."
2. Postal letters or packages which can be safely sorted by mail machinery: "Some post offices have machinable equipment that function as parcel sorters."
