| modulus | Origin: L, a small measure. See Module. <mathematics> A quantity or coefficient, or constant, which expresses the measure of some specified force, property, or quality, as of elasticity, strength, efficiency, etc.; a parameter. Modulus of a machine, a formula expressing the work which a given machine can perform under the conditions involved in its construction; the relation between the work done upon a machine by the moving power, and that yielded at the working points, either constantly, if its motion be uniform, or in the interval of time which it occupies in passing from any given velocity to the same velocity again, if its motion be variable; called also the efficiency of the machine. <mathematics> Modulus of a system of logarithms, a number by which all the Napierian logarithms must be multiplied to obtain the logarithms in another system. Modulus of elasticity. The measure of the elastic force of any substance, expressed by the ratio of a stress on a given unit of the substance to the accompanying distortion, or strain. An expression of the force (usually in terms of the height in feet or weight in pounds of a column of the same body) which would be necessary to elongate a prismatic body of a transverse section equal to a given unit, as a square inch or foot, to double, or to compress it to half, its original length, were that degree of elongation or compression possible, or within the limits of elasticity; called also Young's modulus. Modulus of rupture, the measure of the force necessary to break a given substance across, as a beam, expressed by eighteen times the load which is required to break a bar of one inch square, supported flatwise at two points one foot apart, and loaded in the middle between the points of support.

| modulus of elasticity | A coefficient expressing the ratio between stress per unit area acting to deform a body and the amount of deformation that results from it. Modulus of volume elasticity, a coefficient expressing the ratio between pressure acting to change the volume of a substance and the amount of change that results from it. Synonym: bulk modulus. Young's modulus, a type of modulus of elasticity which specifies the force applied to a body in one direction, per unit cross-sectional area of the body perpendicular to that direction, divided by the fractional change in length of the body in that direction.

| hydraulic | Of or pertaining to hydraulics, or to fluids in motion; conveying, or acting by, water; as, an hydraulic clock, crane, or dock. Hydraulic accumulator, an accumulator for hydraulic machinery of any kind. See Accumulator. Hydraulic brake, a cataract. See Cataract. Hydraulic cement, a cement or mortar made of hydraulic lime, which will harden under water. Hydraulic elevator, a lift operated by the weight or pressure of water. Hydraulic jack. See Jack. Hydraulic lime, quicklime obtained from hydraulic limestone, and used for cementing under water, etc. Hydraulic limestone, a limestone which contains some clay, and which yields a quicklime that will set, or form a firm, strong mass, under water. Hydraulic main An inverted cup with a partition dipping into water, for opening or closing communication between two gas mains, the open ends of which protrude about the water. Origin: F. Hydraulique, L. Hydraulicus, fr. Gr, a water organ; "ydwr water + flute, pipe. See Hydra. Source: Websters Dictionary (01 Mar 1998) |
| hydraulic conductivity | Ease of pressure filtration of a liquid through a membrane; specifically, Kf = η(Q/A) (dx/dP), where Kf = hydraulic conductivity, η = viscosity of the liquid being filtered, Q/A = volume of liquid filtered per unit time and unit area, and dx/dP = reciprocal of the pressure gradient through the membrane; solute concentrations should be identical on both sides of the membrane. Also applied more loosely to measurements on a total membrane of unknown area and thickness with unmeasured fluid viscosity (K = Q/dP). (05 Mar 2000) |
| hydraulic load | Amount of liquid going into a system. (05 Dec 1998) |
| hydraulic motor | By altering the internal osmotic pressure within a cell, water will enter and a considerable expansion of the compartment will occur. This has been used as a motor device in plants (turgor pressure), in eversion of nematocysts and possibly in the production of other cellular protrusions. (18 Nov 1997) |
