)
The size of some one part,
as the diameter of semi-diameter of the base of a shaft, taken as a
unit of measure by which the proportions of the other parts of the
composition are regulated. Generally, for columns, the semi-diameter
is taken, and divided into a certain number of parts, called
minutes (see Minute), though often the diameter is
taken, and any dimension is said to be so many modules and
minutes in height, breadth, or projection.Mod"ule, v. t. [See module,
n., Modulate.] To model; also, to
modulate. [Obs.] Sandys. Drayton.
||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.
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.
