A temporary magnet is one in which the domains do not remain aligned after the magnetizing force is removed.

A device which converts mechanical force and motion into pneumatic flow power.


A permanent magnet placed vertically in a tube under the center of a marine magnetic compass, to correct for heeling error.


The oscillatory vertical rise and fall, due to the entire hull being lifted by the force of the sea. Also called HEAVING


The resisting force encountered at the common boundary between two bodies when, under the action of an external force, one body, moves or tends to move relative to the surface of the other.


A device which converts mechanical force and motion into hydraulic fluid power.


Any substance that flows readily or changes in response to the smallest influence. More generally, any substance in which the force required to produce a deformation depends on the rate of deformation rather than on the magnitude of the deformation.


Heeling adjuster. Also called VERTICAL FORCE INSTRUMENT


A measure of viscosity (absolute viscosity) numerically equal to the force required to move a plane surface of one square centimeter per second when the surfaces are separated by a layer of fluid one centimeter in thickness. It is the ratio of the shearing stress to the shear rate of a fluid and is expressed in dyne seconds per square centimeter (DYNE SEC/CM2); 1 centipoise equals .01 poise.


The time required for a fixed amount of an oil to flow through a capillary tube under the force of gravity. The unit of kinematic viscosity is the stoke or centistoke (1/100 of a stoke). Kinematic viscosity may be defined as the quotient of the absolute viscosity in centipoises divided by the specific gravity of a fluid, both at the same temperature Centipoises / Specific Gravity = Centistokes .


A filter element that, in addition to its filter medium, has a magnet or magnets incorporated into its structure to attract and hold ferromagnetic particles.
