From The Collaborative International Dictionary of English v.0.48 :

  Modulus \Mod"u*lus\, n.; pl. Moduli. [L., a small measure. See
     Module, n.] (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.
     [1913 Webster]
  
     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. --Mosley. --Rankine.
  
     Modulus of a system of logarithms (Math.), a number by
        which all the Napierian logarithms must be multiplied to
        obtain the logarithms in another system.
  
     Modulus of elasticity.
     (a) 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.
     (b) 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. --Rankine.
        [1913 Webster]
