You never thought about the fact that your car racing has a good gyro, and not one? But they are made and put into place your own hands! Their role is carried out by the engine flywheel and gear wheels. In the not-so-small mass and size, the frequency of their rotation is so large that such is not always seen in the “adult” technique.
The gyroscopic effect, which characterizes the desire of a rapidly rotating mass to keep its position in space, fully manifested in the races of micromachines on track. How? Let’s try to understand. First of all, agree that the moment the front wheels on the behavior of the model can be neglected — they have compared to back minor mass and smaller diameter.
After preliminary transformations of the obtained formula to determine the gyroscopic moment in the conditions (the radius of movement of the micro-car, only according to the rules of the competition is equal to 995 cm):
M = 14,89·10-7·P·R2·n·V (g·cm),
P – the weight of the flywheel or wheel, g,
R is the radius of the flywheel or the wheels, cm,
n – frequency of rotation of the flywheel or the wheels rpm
V – model speed, km/h.
When analyzing influence on the behavior of the model the gyroscopic moment of the flywheel can be considered the four possible cases: 1 — the model moves counter-clockwise motor rotates counterclockwise 2 — model moves in a clockwise direction, the motor rotates counterclockwise, 3 — model moves counterclockwise, the motor rotates clockwise, the 4 — model moves in a clockwise direction, the motor rotates clockwise.
