  • noun Physics A quantity that expresses the degree to which a substance possesses a property, such as elasticity.
  • noun The square root of the product of a complex number and its complex conjugate.
  • noun A natural number used as a specified divisor in modular arithmetic.
  • noun The number by which a logarithm in one system must be multiplied to obtain the corresponding logarithm in another system.

from The Century Dictionary.

  • noun In mathematics, a real positive number that serves as measure or parameter of a function or effect. Represented by M. or μ.
  • noun In physics, the measure of an effect under conditions whose measure is unity. Thus, a physical modulus is not a number, but a physical quantity.
  • noun [capitalized] In conchology, a genus of gastropods, referred to the Littorinidæ or periwinkles, or made type of the family Modulidæ. The shell is depressed and trochiform, with a deeply cut columellar tooth and many-whorled operculum.
  • noun then the modulus of transformation is

  • noun (Math., Mech., & Physics) 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.
  • noun 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.
  • noun (Math.) a number by which all the Napierian logarithms must be multiplied to obtain the logarithms in another system.
  • noun 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.
  • noun 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.
