Equilibria

Equilibrium / Equilibria
Equilibrium means balance. A system that does not tend to undergo any change of its own accord but remains in a single, fixed state is said to be in equilibrium. There are two types of equilibrium:
 * Static Equilibrium ( this is unnatural and is very unlikely to happen in an uncontrolled environment)
 * Steady-State equilibrium

Steady State equilibrium is an average condition where the overall situations remains fairly constant. Over time, inputs into the system equals output, so there is no net change.
 * Steady-State Equilibrium**

In order for a system to maintain a steady state, it must be able to **self regulate**. Self regulation is usually controlled by negative feedback and positive feedback mechanism. A system will not usually exist in steady state.
