Restoring Stability Of Motor Cycle
Physically, a motorcycle is what we call an inverted pendulum. In a normal pendulum, we have a fixed point and a mass hanging below it. If we move a little dough on your site, gravity will pull him and, therefore, will fall under its own weight. That is, a simple pendulum back by itself to the equilibrium position, we say that is a stable system.
However, a donkey does just the opposite. The fixed point (where the wheels make contact with the pavement) is below the mass. Can be kept in balance only if the center of gravity remains just above the line joining the two wheels. But any deviation, however small, will make the weight throw it down. That is, by itself inverted pendulum tends to move away from the equilibrium position is an unstable system.
As usually do not want our bones are given to the ground, we must compensate as quickly as possible with any small deviation occurs. It is imperative to make the center of gravity is back on the line connecting the contact points of each wheel with the ground. There are essentially two ways to do it.
The first way is to let the wheels still, and simply change places the center of gravity to return to the line of stability. For example, if the bike is starting to tilt to the right, we can do is shift your body to the left. The repositioning of our body, corrects the position of center of gravity of the motorcycle-rider system, restoring stability.
