Technical Science and Engineering

(engineering is the technical science in which properties of matter and the sources of power in nature are made useful to people; such as, in structures, devices, machines, and products)

aggregate (s) (noun), aggregates (pl)
A mixture of several materials; for example, aggregates of gravel, natural sand, and crushed stone are used for making concrete.
alloy (s) (noun), alloys (pl)
A substance which has metallic properties, and that consists of two or more elements; usually, at least one of which is a metal.
alternator (s) (noun), alternators (pl)
Types of alternating-current generators.
ammeter (s) (noun), ammeters (pl)
An instrument, or instruments, which measure the strength of electric currents in amperes.
anneal (verb), anneals; annealed; annealing
1. The process of making glass, metal, or alloy less brittle by exposing it to heat and then to being cooled.
2. To subject glass or metal to a process of heating and then slow cooling in order to toughen and to reduce brittleness.
cantilever (s) (noun), cantilevers (pl)
Beams or other kinds of horizontal structures each of which is supported only on one end.
cathode-ray tube, CRT (s) (noun); cathode-ray tubes (pl)
A tube in which an electron beam is directed across a fluorescent tube so it will generate images.

The cathode-ray tubes are used in oscilloscopes, radar, television sets, and computer monitors.

ceramic matrix composites (noun) (plural form used as a singular)
Materials fabricated from ceramic fibers embedded in a ceramic matrix; for example glass ceramics.

The are developed so they will be stronger, more pliable, and more heat-resistant and cold-resistant than other materials.

circuit (s) (noun), circuits (pl)
A line of conductors and other electrical devices along which electrical currents flow.

Closed circuits permit the currents to travel through all devices; so, if the circuits are broken at some point where the currents can't flow, they are called open circuits.

coil (s) (noun), coils (pl)
Electric devices consisting of one or more turns of wires which asre used to introduce inductance into electric currents or the properties of electric circuits as a result of which electromotive forces are created by changes of currents.
current (s) (noun), currents (pl)
The flow of electricity; for example, in metals which are good conductors of electric currents.
diode (s) (noun), diodes (pl)
A tube with two electrodes in which the main use of diodes is to keep the electric current flowing in one direction.
dynamo (s) (noun), dynamos (pl)
Types of generatorr; usually, direct-current generators.

The dynamos convert energy of mechanical motions into electric currents.

elasticity (s) (noun), elasticities (pl)
The ability of objects or materials to return to their original sizes and shapes after they have been pushed or pulled by external forces; for example, various kinds of rubber.
electrode (s) (noun), electrodes (pl)
Plates, rods, or wires that are used to conduct electric currents out of or into devices.
