(english) The distortion of a rectangular shape to a skewed parallelogram.
(Software Engineering) a description of the management approach for a project
(english) Sheet metal screws with (a) sharp-pointed ends; and (b) fewer threads per inch than type AB screws; and (c) deeper threads with bettere gripping power than type AB. The industrial Fasteners Institue incorrectly labes type A an “obsolete” thread though it is universally preferred in 18-8 stainless over type AB, especially by the marine industry.
(Environmental Engineering) A virus particle. Viral DNA or RNA enclosed in an organic capsule. See virus.
(Concrete Engineering) Water held on surfaces in a material by either physical and/or chemical forces.
(english) A storage area in Strip Steel used for storing hot bands (coil made from slab).
(english) Appeaars like a series of waves and are created during rolling as a result of mechanical misalignment or cross-section irregularities in supply coil.
(english) A system of internal forces whose resultant is a moment. This term is most commonly used to refer to internal forces in beams.

(english) A process of annealing a ferrous alloy in a closed metal container, with or without packing materials, in order to minimize the effects of oxidation. The charge is normally heated slowly to a temperature below the transformation range, but occasionally above or within it, and then is slowly cooled.
(Concrete Engineering) A siliceous, or siliceous and aluminous material, which in itself possesses little or no cementitious value but will, in a finely divided form, such as a powder or liquid and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form permanent, insoluble compounds possessing cementitious properties.
(english) Flexibility is the inverse of stiffness. When a force is applied to a structure, there is a displacement in the direction of the force; flexibility is the ratio of the displacement divided by the force. High flexibility means that a small load produces a large displacement.
