7 unusual facts about Mechanical equilibrium


Boltzmann relation

In a plasma, the Boltzmann relation describes the number density of an isothermal charged particle fluid when the thermal and the electrostatic forces acting on the fluid have reached equilibrium.

Dynamic relaxation

6. Return to step 3 until the structure is in static equilibrium

Fluid

These properties are typically a function of their inability to support a shear stress in static equilibrium.

Mechanical equilibrium

In addition, this definition gives no information as to one of the most important and interesting aspects of equilibrium states—their stability.

Plasma stability

It usually only makes sense to analyze the stability of a plasma once it has been established that the plasma is in equilibrium.

Rayleigh–Taylor instability

The equilibrium here is unstable to any perturbations or disturbances of the interface: if a parcel of heavier fluid is displaced downward with an equal volume of lighter fluid displaced upwards, the potential energy of the configuration is lower than the initial state.

Stability derivatives

where Y 0 is the force corresponding to the equilibrium condition (usually called the trim) whose stability is being investigated.
