absolute pressure Is zero-referenced against a perfect vacuum, using an absolute scale, so it is equal to gauge pressure plus atmospheric pressure. absolute scale Any system of measurement that begins at a minimum, or zero point, and progresses in only one direction. The zero point of an absolute scale is a natural minimum, leaving only one ...
Bearing pressure – a particular case of contact mechanics often occurring in cases where a convex surface (male cylinder or sphere) contacts a concave surface (female cylinder or sphere: bore or hemispherical cup). Excessive contact pressure can lead to a typical bearing failure such as a plastic deformation similar to peening.
AAW An acronym for anti-aircraft warfare. aback (of a sail) Filled by the wind on the opposite side to the one normally used to move the vessel forward.On a square-rigged ship, any of the square sails can be braced round to be aback, the purpose of which may be to reduce speed (such as when a ship-of-the-line is keeping station with others), to heave to, or to assist moving the ship's head ...
In electrochemistry, according to an IUPAC definition, [1] is the electrode potential of a metal measured with respect to a universal reference system (without any additional metal–solution interface). Absolute pressure is zero-referenced against a perfect vacuum, using an absolute scale, so it is equal to gauge pressure plus atmospheric ...
Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as 1 ⁄ 760 of this. Manometric units such as the centimetre of water , millimetre of mercury , and inch of mercury are used to express pressures in terms of the height of column of a particular ...
Follow @SelenaMaranjian Hearing about tax shelters used by the rich can get many of us steamed. One technique recently in the news is the "Walton grantor retained annuity trust," or GRAT, which ...
Thursday's failure upped the pressure on Republican House Speaker Mike Johnson, who leads a fractious and narrow majority and has often had to rely on Democratic votes to pass key pieces of ...
Pressure core sampler: A tool designed to retrieve a sediment core sample while retaining the pressure at depth. [5] Pull past Martin-Decker: Exert extreme tension on stuck pipe, so much so that the pointer needle revolves off-scale beyond the logo of a popular manufacturer of weight indicators, Martin-Decker.
