Statically equivalent:

(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.

Blow Back

(english) A coating defect consisting of a lower coating film weight on the bottom of the coated sheet caused by high velocity air in the oven. Blow back usually occurs with high solids coatings which have little solvent to evaporate and "set" the film.

Linear Elastic:

(english) A force-displacement relationship which is both linear and elastic. For a structure, this means the deformation is proportional to the loading, and deformations disappear on unloading. For a material, the concept is the same except strain substitutes for deformation, and stress substitutes for load.

Balling Drum

(english) A rotating drum that is used for adding moisture to the sinter mix in the Blast Furnace. Also, it enhances a balling action where the smaller sized materials adhere to larger materials.

Moment of inertia (I):

(english) Moment of inertia has two distinct but related meanings: 1) it is a property of a an object relating to the magnitude of the moment required to rotate the object and overcome its inertia. 2) A property of a two dimensional cross section shape with respect to an axis, usually an axis through the centroid of the shape.

Brinell Hardness Testing

(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.

Kelly Ball

(Concrete Engineering) A device for determining the consistency of fresh concrete. It is sometimes used as an alternative to the slump test.

Substrate level phosphorylation

(Environmental Engineering) The synthesis of the energy storage compound adenosine triphosphate (ATP) from adenosine diphosphate (ADP) using organic substrates without molecular oxygen.

Aesthetic design

(Software Engineering) a Web engineering action that focuses on the aesthetics (e.g., the artistic elements) of a WebApp (often encompasses graphic design)

Basic Oxygen Furnace (BOF)

(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Quality function deployment (QFD)

(Software Engineering) a technique that translates the needs of a customer in technical requirements for software by assessing the value of each requirement

Belt Wrapper

(english) Line equipment used in the Tin Mill for starting coils on prime or reject reels. The belt wrapper ensures a proper start.
