And scientists, and all the other believe that it is understandable why the design of the bicycle allows it to maintain excellent stability. However, the simple experiment refutes the standard theories.
It is believed that to preserve the balance of the bike the most important role is played by two mechanisms. The first - an automatic steer: If the wheel leans in any direction, the front wheel is rotated to the same self, begins to turn the whole bike, and the centrifugal force of the wheel returns to its initial position. It also comes back and when driving in a straight line, after an accidental deviation in the direction. The second mechanism is associated with the gyroscopic moment of the rotating wheel.
It's pretty simple - but the American engineer Andy Ruin (Andy Ruina) and colleagues undertook to refute both claims. They have designed a bike, in which the effects and of both the mechanism of offset. Unlike all the ... And in addition, and front and rear wheels are connected to two other, rotating in the opposite direction and thereby nulled gyroscopic effect.
Of course, all this looks more like a machine of some custom -bike (read about them: ... Just to push - and see how fast it will fall on its side! .
According to the results of the experiment, the authors make a clear conclusion: the two effects - and Castor, and gyro - play an important role in maintaining the balance of riding a bicycle, but neither of them are critically important for him. Note that the construction of a bike with no gyroscopic moment has already been tested previously, but the denial of the crucial role of Castor in maintaining the balance of the bike was first done, and very clearly.
So why is the bike does not fall? . As a result, the front wheel collapses faster than the rear, and since they are rigidly connected to the vertical axis, the front wheel instead of just leaning to one side, set in the same direction, correcting the position of the bicycle.
