Gyro preservation of fitness gyro

Gyroscope should be stored in a cool and ventilated place to avoid cracking in the sun, damp and mildew. If necessary, air conditioners or dehumidifiers should be used to dehumidify the storage places. Iron parts should be oiled and maintained in a timely manner (not too much, so as to avoid easy rope entanglement); If the rope feels hard, it should be soaked in water, washed, beaten (to remove sand and dust) and then dried in the shade.

Gyroscope is a familiar toy for primary and middle school students. A small gyro is spinning fast on the desktop. Seeing that it is still, on the one hand, it rotates rapidly around the axis inclined to the desktop, and on the other hand, it rotates slowly and steadily around the axis perpendicular to the desktop like a conical generatrix.

Why doesn't the top fall off when it rotates? Of the thousands of people who play gyro, probably few can answer this question correctly. Indeed, the rotation of the gyro is very interesting and mysterious.

Gyroscope has high research value in science. Throw the gyro into the air. It can keep its axis in the original direction. Using this characteristic of gyroscope to manufacture directional gyroscope is widely used in navigation, aviation and aerospace fields.
