Fr.: mécanique analytique
A branch of → mechanics based on → variational principle that describes systems by their → Lagrangian or → Hamiltonian. Analytical mechanics provides a formalism that is different from that of Newton and does not use the concept of force. Among other things, analytical mechanics gives a more simple description of continuous and constrained systems. Moreover, its mathematical structure allows it an easier transition to quantum mechanical topics.
mekânik-e âsmâni (#)
Fr.: mécanique céleste
The branch of astronomy that deals with the calculation of motions of celestial bodies under the action of their mutual gravitational attractions.
mekânik kelâsik (#)
Fr.: mécanique classique
The branch of physical science which deals with the motions of bodies travelling at velocities that are very much less than that of light in a vacuum. Same as → Newtonian mechanics.
Fr.: mécanique des fluides
A person who repairs and maintains machinery, motors, etc. (Dictionary.com). Same as → mechanician.
1) Of, connected with, produced by → mechanics.
Fr.: énergie mécanique
Fr.: équilibre mécanique
1) The state of a → rigid body if, as viewed from an
→ inertial frame of rest: 1) the
→ linear acceleration of its
→ center of mass is zero, and 2) its
→ angular acceleration about any axis
fixed in this reference frame is zero. The center of mass may
be moving with constant velocity and the body may be rotating
about a fixed axis with constant angular velocity.
mechanical equivalent of heat
ham-arz-e mekâniki-ye garmâ (#)
Fr.: équivalent mécanique de chaleur
Same as → Joule's constant.
Fr.: mélange mécanique
tavân-e mekâniki (#)
Fr.: puissance mécanique
Fr.: système mécanique
1) Any system of elements that interact according to the laws of
→ mechanics (as distinguished from chemical,
electrical, thermal, etc.).
Fr.: vent mécanique
A process in which matter is shed into a → Keplerian disk from a star rotating at the → critical velocity. The disk is probably destroyed by the pressure exerted by the stellar radiation and finally matter is lost. Such a process seems to occur around → Be stars which are stars rotating at or very near the critical limit (Meynet et al. 2007, arXiv:0709.2275).
1) In a mechanical manner; by a mechanism.
A person skilled in constructing, working, or repairing machines; mechanic; machinist (Dictionary.com).
From → mechanic + -ian.
mekânik (#), sâzokârik
mekânik-e Newtoni (#)
Fr.: mécanique newtonienne
Fr.: mécanique non-relativiste
Mechanics in which the masses under consideration move at speeds much slower than the speed of light.
quantum mechanical system
râžmân-e kuântom mekâniki
Fr.: système mécanique quantique
kuântom mekânik, mekânik-e kuântomi
Fr.: mécanique quantique
A development of Newtonian mechanics based on the discrete character of energy (Planck 1900) and the wave motion of material particles (de Broglie 1924). It is relies on the consideration that energy state of a quantum mechanical system can be derived at a given instant by a function whose square of the modulus gives the probability distribution of the coordinates of the system. Quantum mechanics is essential for the treatment of all atomic processes. It holds also for ordinary large scale processes although in this case the deviations from Newtonian mechanics are negligible.
