What is the difference between stability and equilibrium?
As nouns the difference between stability and equilibrium is that stability is the condition of being stable or in equilibrium, and thus resistant to change while equilibrium is the condition of a system in which competing influences are balanced, resulting in no net change.
What are the difference between stable and unstable equilibrium?
A system is said to be in stable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in a direction opposite to the direction of the displacement. A system in unstable equilibrium accelerates away from its equilibrium position if displaced even slightly.
What do you understand by equilibrium of system of forces explain different types of equilibrium and the conditions of equilibrium?
A force is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.
What term means a state of stability or equilibrium?
Stable equilibrium can refer to: Homeostasis, a state of equilibrium used to describe organisms. Mechanical equilibrium, a state in which all particles in a system are at rest, and total force on each particle is permanently zero.
What is stable and unstable equilibrium in economics?
stable and unstable equilibria of an economic system. A stable equilibrium. presents itself, when after a slight haphazard deviation the system moves back. to the original position. An unstable equilibrium exists when the system does.
How does stability affect equilibrium?
The stability of a system is intimately connected to its equilibrium state. If a system in equilibrium is disturbed slightly, then if it is stable it tends to return to or oscillate about its original equilibrium state.
What is the difference between stable and unstable electronic configuration?
Stable electronic configuration: Atoms having octet (8 electrons) or duplet 2 electrons in outermost shell is stable electronic configuration 2 electrons in K shell the valence shell. Unstable electronic configuration: “Atoms of the element which do not have their valence shells completely filled.”
What is equilibrium system?
A chemical reaction is in equilibrium when the concentrations of reactants and products are constant – their ratio does not vary. Another way of defining equilibrium is to say that a system is in equilibrium when the forward and reverse reactions occur at equal rates.
Why is it called equilibrium?
Equilibrium contains a root from the Latin libra, meaning “weight” or “balance”. Equilibrium has special meanings in biology, chemistry, physics, and economics, but in all of them it refers to the balance of competing influences.
What is the stability of equilibrium solution?
Stability of an equilibrium solution The stability of an equilibrium solution is classified according to the behavior of the integral curves near it – they represent the graphs of particular solutions satisfying initial conditions whose initial values, y0, differ only slightly from the equilibrium value.
How do you know if a solution is stable?
If the nearby integral curves all converge towards an equilibrium solution as t increases, then the equilibrium solution is said to be stable, or asymptotically stable. Such a solution has longterm behavior that is insensitive to slight (or sometimes large) variations in its initial condition.
How do you know if an equilibrium point is unstable?
If the force on either side of an equilibrium point has a direction opposite from that direction of position change, the equilibrium is termed unstable, and this implies that U ( x) has a relative maximum there. The potential energy for a particle undergoing one-dimensional motion along the x -axis is where U is in joules and x is in meters.
How do you determine the stability of a structure?
The number of external reactions is often the simplest means to determine the stability of a structure. They must be greater than the number of equations available for the structure to remain in static equilibrium.
