“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world”


Leverage is the advantage gained by the use of a lever. It is one of the six simple machines identified by Renaissance scientists. Archimedes proved the law of the lever using geometric reasoning: M1A = M2B . The equation shows that, if the distance of the input force to the fulcrum is greater than the distance from fulcrum to the output force, then the lever amplifies the input force. The applied input force is normally called the effort and the output force is the resistance. The influence of the applied force which tends to change the rotational motion of an object is due to this torque or moment of the force. The longer the length of the lever arm, the larger the torque along the axis of the rotation.

The Greek physicist, mathematician, and engineer Archimedes introduced the concept of center-of-mass, which is the concept on which the law of the lever rests. The center of mass is the point at which all the mass can be considered to be “concentrated.” When, an object is supported at its center of mass, there is no net torque acting on the body and therefore it will remain in static equilibrium. However, the lever is simply a movable bar that pivots on a fulcrum or pivot point that can change in position, and provide leverage by applying forces at different distances from the fulcrum, or the pivot.

In many ways gears act in rotating systems, as do levers, in translating systems. A gear ratio can either increase the output torque or the output speed of a mechanism. A classic example would be the gears on a bicycle. A low gear provides a lower speed that allows one to pedal easily up hill; conversely, a high gear provides a higher bicycle speed. Levers and gears are used in many mechanical devices, and have several important jobs in our lives.



“Fair play doesn't pertain in bargaining. What matters there is leverage”

Alan Rosenberg

A seesaw is a type of a lever. If you sit farther away from the fulcrum, you can lift a much heavier weight. Leverage provides a power to lift objects you'd never be able to budge by yourself.  Leverage includes positive, negative, and normative.

Normative leverage occurs when both parties are aware of the standards and norms and are negotiating for their own good. This is normally a win-win situation for both parties; each party uses different means and methods to advance one's own arguments for the desired outcome.  In normative leverage, the lever is pushed back and forth between the parties to achieve a balance. You are using the neutral gear, creating equilibrium between values, desire and emotions so that you are able to fully enjoy life without giving too much or expecting too much from the other party.

Negative leverage is when one uses his ability to cause suffering to his opponent. This can be a very powerful and vicious game, especially if the attack is aimed at the opponent’s core beliefs. When leverage is taken against someone’s weakness, conflicts or unsure values, or lack of clarity, it needs a much bigger force (resistance) to equalize the lever. The secret of pushing the lever back is to be honest with yourself, be authentic, and only play the games of your choice.

Positive leverage is one's ability to provide for his opponent without an expected return; or in simpler terms, generous giving. You no longer compete for the lever in this situation, you save and give and the effects are magnificent in this case. You multiply your power by utilizing gratitude and kindness. This brings you closer to yourself, creates love, saves time, and gives you a chance to focus on other deliberations that drive you forward.
