mechanical
  ساز-و-کاریک، ساز-و-کاروار   
sâzokârik, sâzokârvâr

Fr.: mécanique   

1) Of, connected with, produced by → mechanics.
2) Like machines; automatic.

mechanic; → -al.

mechanical energy
  کاروژ ِ مکانیکی   
kâruž-e mekâniki

Fr.: énergie mécanique   

The energy that is possessed by an object due to its motion or due to its position. It is equal to the sum of the → kinetic energy and → potential energy.

mechanical; → energy.

mechanical equilibrium
  ترازمندی ِ مکانیکی   
tarâzmandi-ye mekâniki

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.
2) In → thermodynamics, the state of a system in which → pressure is the same every where with no other forces acting on the system except a uniform external pressure.

mechanical; → equilibrium.

mechanical equivalent of heat
  هم‌ارز ِ مکانیکی ِ گرما   
ham-arz-e mekâniki-ye garmâ (#)

Fr.: équivalent mécanique de chaleur   

Same as → Joule's constant.

mechanical; → equivalent; → heat.

mechanical mixing
  آمیزش ِ مکانیکی   
âmizeš-e mekâniki

Fr.: mélange mécanique   

Any → mixing process that utilizes the → kinetic energy of relative → fluid motion.

mechanical; → mixing.

mechanical power
  توان ِ مکانیکی   
tavân-e mekâniki (#)

Fr.: puissance mécanique   

The → rate at which → work is done by a → force. In other words, → mechanical energy per unit time. Mechanical power is expressed in units of joules/sec (joules/s) or a watt (W) in the → mks system.

mechanical; → power.

mechanical system
  راژمان ِ مکانیکی   
râžmân-e mekâniki

Fr.: système mécanique   

1) Any system of elements that interact according to the laws of → mechanics (as distinguished from chemical, electrical, thermal, etc.).
2) A collection of → machines functioning together to achieve the transfer of motion.

mechanical; → system.

mechanical wind
  باد ِ مکانیکی   
bâd-e mekâniki

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).

mechanical; → wind.

mechanically
  ساز-و-کاریکانه، ساز-و-کاروارانه   
sâzokârikâné, sâzokârvârâné

Fr.: mécaniquement   

1) In a mechanical manner; by a mechanism.
2) In a machine-like manner; without feeling.

mechanical; → -ly.

quantum mechanical system
  راژمان ِ کو‌آنتوم مکانیکی   
râžmân-e kuântom mekâniki

Fr.: système mécanique quantique   

A → physical system that is specified by a → wave function.

quantum; → mechanical; → system.

quantum-mechanical operator
  آپارگر ِ مکانیک ِ کو‌آنتومی   
âpârgar-e mekânik-e kuântomi

Fr.: opérateur en mécanique quantique   

A linear → Hermitian operator associated with a physical quantity.

quantum; → mechanics; → operator.
