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.

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.
