{
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 . --

{
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 '

{
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 . --
