  • Interesting fact: Slinkys were invented by an airplane mechanic; he was playing with engine parts and realized the possible secondary use of one of the springs
    • n Mechanics That science, or branch of applied mathematics, which treats of the action of forces on bodies.☞ 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.

  • Interesting fact: The Liberty Bell was the first mechanical slot machine, which was invented by Charles Fey, a car mechanic in 1895.
    • n mechanics The theory of machines. This is the old meaning of the word, especially before the development of the modern doctrine of force.
    • n mechanics The mathematical doctrine of the motions and tendencies to motion of particles and systems under the influence of forces and constraints; in a narrower sense, this doctrine as applied to systems of rigid bodies. Mechanics is now commonly divided into kinematics and dynamics. and the latter into statics and kinetics. Mechanics treated by means of the infinitesimal calculus is called analytical mechanics. The fundamental principles of mechanics are stated under energy and force; but the science is characterized by the great number of derived principles made use of. See principle.
    • n mechanics The science which explains natural phenomena by depicting them with mathematical precision as dependent solely upon relations of motion.

    • Mechanics the science which treats of machines: the science which treats of the nature of forces and of their action on bodies, either directly or by the agency of machinery
