An arc lamp or arc light is a lamp that produces light by an electric arc.
Arc suppression is the reduction of sparks formed when current-carrying contacts are separated.
Arc welding is the fusing of two metals using heat produced by an electric arc formed between them.
An arc-fault circuit interrupter is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring.
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments.
An arch-gravity dam is a dam with the characteristics of both an arch dam and a gravity dam.
A body immersed in fluid is subject to an upwards force equal to the weight of the fluid displaced.
An electric arc may form between power system conductors and ground where the system voltage is high enough.

An inert gas used to shield the molten metal during argon arc welding.
The Argonaut class reactor is a design of small nuclear research reactor. Its functions are to teach nuclear reactor theory, nuclear physics and for use in engineering laboratory experiments.
In electrical engineering, an armature is the component of an electric machine which carries alternating current.
In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity.
Aromatic compounds are those chemical compounds (most commonly organic) that contain one or more rings with pi electrons delocalized all the way around them.
A vessel passing through the locks shall normally be assisted by locks locomotives using steel towing wires. Article 59 of the Regulations on Navigation in Panama Canal Waters (www.pancanal.com) defines...
By “Arrest” is meant the detention of a ship because of some infringement of regulations, either port or national. When a maritime lien is to be exercised the ship may also be “arrested”.
Artificial intelligence is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals, which involves consciousness and emotionality.
A human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, offshore wind farms are contributing to the creation of artificial reefs.
Artificiality (the state of being artificial or human-made) is the state of being the product of intentional human manufacture rather than occurring naturally through processes not involving or requiring human activity.
