Standard pressure and temperature. See standard air.

Mobile truck equipment with the capacity for lifting a container within its own framework.

A non-negotiable bill of lading which states a specific identity to whom the goods should be delivered. See Bill of Lading.

The unit of change in the size or shape of a body due to force. Also known as nominal strain.

Aging induced by cold working.

An increase in hardness and strength caused by plastic deformation at temperatures below the recrystallization range.

The time rate of straining for the usual tensile test. Strain as measured directly on the specimen gage length is used for determining strain rate. Because strain is dimensionless, the units of strain rate are reciprocal time.

A loss in ductility accompanied by an increase in hardness and strength that occurs when low-carbon steel (especially rimmed or capped steel) is aged following plastic deformation. The degree of embrittlement is a function of aging time and temperature, o ...

Filtering device used to remove the solid debris from the cooling water.

A device used to separate air solids from the stream of air that might become a source of trouble. Adulterants caught in the strainer are blown out through an orifice fitted with a valve or plug. The strainer should be opened periodically for a thorough c ...

On wooden boats, a line of planking running from the bow to the stern along the hull.

A continuous planking or plating fitted out to and from stem to stern of a vessel's side.

A number of yarns, twisted together and which in turn may be twisted into rope; a rope is stranded when a strain is broken; rope may be designated by the number of strands composing. Rope is commonly three-stranded. A vessel run ashore is said to be stran ...

An investment in a power plant or demand side management measures or programs, that become uneconomical due to increased competition in the electric power market. For example, an electric power plant may produce power that is more costly than what the mar ...

A ring of rope made by splicing the ends, and used for slinging weights, holding the parts of a block together, etc. A rope, wire or iron binding, encircling a block and with a thimble seized into it for taking a hook.

Current flowing through paths other than the intended circuit.

Corrosion resulting from direct current flow through paths other than the intended circuit. For example, by an extraneous current in the earth.

Same as river gauge.

The intensity of the internally distributed forces or components of forces that resist a change in the volume or shape of a material that is or has been subjected to external forces. Stress is expressed in force per unit area and is calculated on the basi ...

A multiplying factor for applied stress that allows for the presence of a structural discontinuity such as a notch or hole; Kt equals the ratio of the greatest stress in the region of the discontinuity to the nominal stress for the entire section. Also ca ...
