(english) An object is in equilibrium if the resultant of the system of forces acting on it has zero magnitude. See static equilibrium and dynamic equilibrium.
(Software Engineering) when a defect is introduced early in the software process and remains undetected, it often is amplified into multiple defects later in the software process
(Software Engineering) changing software in a way that improves its internal structure but does not change it external behavior; often conducted iteratively as design evolves into code.
(Environmental Engineering) (FSS) is the matter remaining from the suspended solids analysis which will not burn at 550°C. It represents the non-filterable inorganic residue in a sample.
(english) The resultant of a system of forces is a single force or moment whose magnitude, direction, and location make it statically equivalent to the system of forces.
(english) The customer buys by the actual (scale) weight of the steel. The theoretical weight is used in estimating, however, it is not to be used for billing.
(Concrete Engineering) A visible lineation which forms when the placement of concrete is delayed. The concrete in place hardens prior to the next placement of concrete against it.
(Software Engineering) a nondimension ratio (between 0 and 1) that provides an indication of the degree to which errors are removed from software before it is released to end-users
(english) A directed interaction between two objects that tends to change the momentum of both.Since a force has both direction and magnitude, it can be expressed as a vector
(english) An alloy containing 90% copper and 10% tin. Used for screws, wire, hardware, wear plates, bushings and springs; it is somewhat stronger than copper and brass and has equal or better ductility.
(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.
(english) An idealized concept meaning something which does not deform under loading. In fact, all objects deform under loading, but in modelling it can be useful to idealize very stiff objects as rigid.
