Beryllium Copper

(english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc.

Bonderized Coating

(english) A thin film of phosphate pretreatment applied to a steel surface (bare or zinc coated) to enhance paintability.

Publicly owned treatment works (POTW)

(Environmental Engineering) A municipal or domestic wastewater treatment facility.

Stability:

(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Accordion Reed Steel

(english) Hardened, tempered, polished and blued or yellow flat steel with dressed edges. Carbon content about 1.00. Material has to possess good flatness, uniform hardness and high elasticity.

POTW

(Environmental Engineering) or Publicly Owned Treatment Works Any municipally owned wastewater treatment facility.

Centroid:

(english) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.

Potential Energy:

(english) The energy stored in a raised object (e.g. the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.
