Gyroscope manufacturing principle

The schematic diagram of gyro production is as follows:

1. Cut the four sides of the milk box down from the opening of the milk box to separate the four sides of the milk box, and then cut off half the length of each side.

2. Round the corners at the ends of the four blades.

3. Draw your favorite color pattern on the leaves. Then stick the plastic bottle cap on the center of the blade with transparent tape, and the position should be opposite when you go up and down.

4. Turning the bottle cap by hand can drive the gyro to rotate, and the pattern on it will produce interesting changes.

Gyroscope principle:

When the gyro rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. In other words, the gyro "rotates" around its own axis and "precesses" around the vertical axis.

The gyro does not stand vertically above the ground, but has a certain deviation from the ground normal and a certain inclination to the ground. Therefore, the moment of gravity on the gyro is not zero, and the precession angular momentum of the gyro can balance the effect of heavy moment, so the gyro will not fall to the ground when it rotates.

The speed at which the gyro "rotates" around its own axis determines the swing angle of the gyro. The slower the rotation, the greater the swing angle and the worse the stability; The faster the rotation, the smaller the swing angle, so the better the stability. Moreover, the shape of the gyro also affects the precession of the gyro.
