n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

n: a device that measures mechanical force. The energy measured is absorbed by frictional or electrical resistance.

abbr: aluminum cable steel- reinforced conductor.

n: a force of attraction that causes molecules of one substance to cling to those of a different substance.

n: The force which holds together unlike molecules.

attractive forces between unlike molecules or compounds. Example – the attractive forces between water molecules and the walls of a clean glass tube are stronger than the cohesive forces;this leads to an upward turned contact or meniscus at the wall.

n: A instrument that measures the force that different substances stick with each other.

n: a federal entity such as a department, a bureau, a corporation, a commission, or a division under the US government that is charged by Congress to administer, implement, and enforce US law. agglomerate n: the groups of larger individual particles usually originating in sieving or drying operations.

n: a group of two or more particles held together by strong forces. Aggregates are stable with normal stirring, shaking, or handling;they may be broken by treatment such as ball milling a powder or shearing a suspension.

n: A group of two or more individual particles held together by strong forces. Aggregates are stable to normal stirring, shaking or handling as powder or a suspension. They may be broken by drastic treatment such as ball milling a powder or by shearing a sus

n: an atmospheric fin tube exchanger that utilises air for cooling. Ambient air contacts the external fins by fanforced or natural draft. Also called air-fin unit or aerial cooler.

n: a body designed to provide a desired reaction force when in motion relative to the surrounding air.

n: an alloy of copper and aluminum that may also include iron, manganese, nickel, or zinc. aluminum cable steel-reinforced
