That science ,
or branch of applied mathematics ,
which treats of the action of forces on bodies .
[
1913 Webster ]
Note :
That part of mechanics which considers the action of forces in producing rest or equilibrium is called {
statics };
that which relates to such action in producing motion is called {
dynamics }.
The term mechanics includes the action of forces on all bodies ,
whether solid ,
liquid ,
or gaseous .
It is sometimes ,
however ,
and formerly was often ,
used distinctively of solid bodies only :
The mechanics of liquid bodies is called also {
hydrostatics },
or {
hydrodynamics },
according as the laws of rest or of motion are considered .
The mechanics of gaseous bodies is called also {
pneumatics }.
The mechanics of fluids in motion ,
with special reference to the methods of obtaining from them useful results ,
constitutes {
hydraulics }.
[
1913 Webster ]
{
Animal mechanics } (
Physiol .),
that portion of physiology which has for its object the investigation of the laws of equilibrium and motion in the animal body .
The most important mechanical principle is that of the lever ,
the bones forming the arms of the levers ,
the contractile muscles the power ,
the joints the fulcra or points of support ,
while the weight of the body or of the individual limbs constitutes the weight or resistance .
{
Applied mechanics },
the principles of abstract mechanics applied to human art ;
also ,
the practical application of the laws of matter and motion to the construction of machines and structures of all kinds .
{
orbital mechanics },
the principles governing the motion of bodies in orbit around other bodies under gravitational influence ,
such as artificial Earth satellites .

1913 Webster PJC ]
