Balance
There are a lot of various specialized definitions, but they all deal with the balance of the system.
When the tightrope walker uses a pole to keep his balance then he is maintaining his equilibrium.
Physics: For example a beam that has a fulcrum in the middle and the same weight at each end would be balanced. If the fulcrum is moved then the shorter end of the beam needs more weight to keep it in balance. This is the lever principle where s small bit of weight can move a larger bit of weight.
According to Wikipedia: http://en.wikipedia.org/wiki/Hydrostatic_equilibrium
"Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance."
In another words the force of gravity is balanced by the force of the fluid. Have you ever seen the bobbing glass bird who keeps sticking his nose into a glass of water and has a bulb of water at its bottom? The reason why it keeps bobbing is that it can't get in equilibrium. As its nose hits the water it cools and so it changes the temperature in the system and it goes up, then it heats up and it goes down.
Chemistry: When you balance an equation.
According to Wikipedia: http://en.wikipedia.org/wiki/Chemical_equilibrium
"In a chemical process, chemical equilibrium is the state in which the chemical activities or concentrations of the reactants and products have no net change over time. Usually, this state results when the forward chemical process proceeds at the same rate as their reverse reaction. The reaction rates of the forward and reverse reactions are generally not zero but, being equal, there are no net changes in any of the reactant or product concentrations. This process is known as dynamic equilibrium."
Biology:
According to Wikipedia: http://en.wikipedia.org/wiki/Homeostasis
“Homeostasis is the property of either an open system or a closed system, especially a living organism, which regulates its internal environment so as to maintain a stable, constant condition. Multiple dynamic equilibrium adjustments, regulation mechanisms, make homeostasis possible. The concept was created by Claude Bernard, often considered as the father of physiology, and published in 1865. The term was coined in 1932 by Walter Bradford Cannon from the Greek homoios (same, like, resembling) and stasis (to stand, posture).
With regard to any given life system parameter, an organism may be a conformer or a regulator. Regulators try to maintain the parameter at a constant level over possibly wide ambient environmental variations. On the other hand, conformers allow the environment to determine the parameter. For instance, endothermic animals maintain a constant body temperature, while ectothermic animals exhibit wide body temperature variation. Examples of endothermic animals include mammals and birds, examples of ectothermic animals include reptiles and some sea creatures.
This is not to say that conformers don't have behavioural adaptations allowing them to exert some control over a given parameter. For instance, reptiles often rest on sun-heated rocks in the morning to raise their body temperature. Likewise, regulators' behaviors may contribute to their internal stability: The same sun-baked rock may host a ground squirrel, also basking in the morning sun.
An advantage of homeostatic regulation is that it allows an organism to function effectively in a broad range of environmental conditions. For example, ectotherms tend to become sluggish at low temperatures, while a co-located endotherm may be fully active. That thermal stability comes at a price since an automatic regulation system requires additional energy. One reason snakes may eat only once a week is that they use much less energy to maintain homeostasis.
Most homeostatic regulation is controlled by the release of hormones into the bloodstream. However other regulatory processes rely on simple diffusion to maintain a balance.”

Basically, if you have a good product that is difficult to duplicate, you are going to have a Monopoly in Nigeria. If you produce things that everyone else is either producing or importing, then you have competition. Equilibrium will be achieved when people are able to compete on price and make choices. Monopolistic competioin is when two monopolies compete within Nigeria who normally would not compete.
