Dictionary Meaning and Definition on 'Mechanics'
- the branch of physics concerned with the motion of bodies in a frame of reference
- the technical aspects of doing something; "a mechanism of social control"; "mechanisms of communication"; "the mechanics of prose style" [syn: mechanism]
- Mechanics \Me*chan"ics\, n. [Cf. F. m['e]canique.]
That science, or branch of applied mathematics, which treats
of the action of forces on bodies.
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.
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.
Wikipedia Meaning and Definition on 'Mechanics'
Mechanics (Greek Μηχανική) is the branch of physics concerned with the behavior of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. The discipline has its roots in several ancient civilizations (see History of classical mechanics and Timeline of classical mechanics). During the early modern period, scientists such as Galileo, Kepler, and especially Newton, laid the foundation for what is now known as classical mechanics.
The system of study of mechanics is shown in the table below:
The major division of the mechanics discipline separates classical mechanics from quantum mechanics.
Historically, classical mechanics came first, while quantum mechanics is a comparatively recent invention. Classical mechanics originated with Isaac Newton's Laws of motion in Principia Mathematica, while quantum mechanics didn't appear until 1900. Both are commonly held to constitute the most certain knowledge that exists about physical nature. Classical mechanics has especially often been viewed as a model for other so-called exact sciences. Essential in this respect is the relentless use of mathematics in theories, as well as the decisive role played by experiment in generating and testing them.[See more about Mechanics at Dictionary 3.0 Encyclopedia]

'Mechanics' in famous quotation sentence
* Relativity keeps anything from happening at once. Quantum mechanics keeps everything from really happening at all. - Lou A. Riley
* The true Church is not an organization, nor does one join it through the noisy mechanics of denominational machinery. Rather it is a living organism, a body, and believers are joined to it by the quiet working of the Holy Spirit. - Cornelius Stam
