Separation of a solid accompanied by little or no macroscopic plastic deformation. Typically, brittle fracture occurs by rapid crack propagation with less expenditure of energy than for ductile fracture.

A decrease in the polarization of an electrode; the elimination or reduction of polarization by physical or chemical means; depolarization results in increased corrosion.

The point or outdoor temperature where the heating capacity of a heat pump matches the heating requirements of a building.

A projecting aperture at the end of a tube, pipe etc. serving as an outlet for compressed air. Reduces the demand on the compressor by generating the highest thrust and volume for the lowest possible air consumption.

A charge for the maximum rate at which energy is used during peak hours of a billing period. That part of a utility service charged for on the basis of the possible demand as distinguished from the energy actually consumed.

The highest continuous deck which runs the full length of the ship without a fall or interruption.

Numerous, very fine cracks in a coating or at the surface of a metal part. Checks may appear during processing or during service and are most often associated with thermal treatment or thermal cycling. Also called check marks. checking, or heat checks.

A fix taken by visually observing the location of known landmarks.

A mechanical/electrical device used to pull air out of an interior space; usually located in the highest location of a building, in the ceiling, and venting to the attic or directly to the outside.

The level at which ice crystals and snowflakes melt as they descend through the atmosphere.

The Captain of a vessel. Highest officer aboard ship. Oversees all ship operations. Keeps ships records. Handles accounting and bookkeeping. Takes command of vessel in inclement weather and in crowded or narrow waters. Handles communications.

A large foresail or jib that overlaps the mainsail. Also known as a genny. Can be expressed in percentages of overlap, e.g. 150 Genoa is 50% overlap of the mainsail.

The part on the object which is hauled upon.

A form of thermal energy resulting from combustion, chemical reaction, friction, or movement of electricity. As a thermodynamic condition, heat, at a constant pressure, is equal to internal or intrinsic energy plus pressure times volume.

A federal agency established in 1933 to develop the Tennessee river valley region of the southeastern U.S., and which is now nation's largest power producer.

Change from a run to a reach

The statement that the viscosity of air is independent of the density of air.

A tax allowance which takes account of depreciation of certain types of business assets such as.
