How to play gyro?

The way to hit the gyro is to whip the gyro continuously to make it rotate on the ice and smooth ground, or collide with each other to see who turns tightly and who turns for a long time.

Gyro is one of the earliest folk entertainment tools in China, also known as sudra. Its upper part is round and its lower part is pointed. It used to be made of wood, but now it is mostly made of plastic or iron. When you play, you can wrap it with a rope and pull it hard to make it rotate upright. The traditional ancient gyro is roughly an inverted cone made of wood or iron, and the game is split with a whip. Gyroscopes emitted by transmitters have been used in modern times.

At present, the methods and forms of gyro competition in national and provincial people's games are mainly transformed from the antagonistic gyro competition of Lahu nationality in Yunnan. The method of competition is to set up a tuo-releasing area and a tuo-playing area on a flat land, and the defender puts the tuo spiral in the tuo-releasing area. After the gyro rotates stably, the attacker stands in the Tuotuo area and throws his rotating gyro to hit the defender's gyro in the Tuotuo area, thus killing or smashing the defender's gyro out of bounds, and the side that keeps rotating wins.

Introduction to the principle of gyroscope

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. In other words, 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, and 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.
