A gyro refers to a rigid body that rotates at a high speed around a fulcrum. The upper part of the shape is round and the lower part is sharp. In the past, it was made of wood, but modern times it is made of plastic or iron. When playing, you can use a rope to wind it up and pull it tightly to make it rotate upright. Or use the spring force of the spring to rotate. The traditional ancient top is roughly an inverted cone made of wood or iron, which is played with a whip. Gyroscopes have been launched by modern transmitters. Of course, some “hand-twisted tops” are very popular. Gyro is a toy that young people are very familiar with. Swept the world.
Paper top Due to the small size of the paper gyro, as long as the thumb and forefinger are used to hold the upper end of the shaft of the paper gyro tightly and twist it quickly on the table, the paper gyro will rotate independently on one foot.
Copper coin top The bronze coin top is also played the same way as the paper top, twist it by hand, and it can rotate.
Spool gyroscope The bobbin gyroscope can also be rotated by hand twisting.
Bamboo spinning top First pass the thick cotton thread through the bamboo sheet, and then wind it on the bamboo handle. Note that it should be wound from top to bottom. When it is entangled, hold the thread end with one hand, draw back, hold the gyro and bamboo with one hand, and push forward. When both hands are forced at the same time, the gyro will rush forward and make a buzzing sound.
Wooden top
Plastic top The plastic elastic gyro is also made of plastic. The gyro is like a small flying saucer, but there is a shaft on the top and bottom, and the gyro is fixed on the pistol-shaped launcher by the pull of a rubber cloth. When playing, turn the gyro with your left hand to tighten the rubber band. After loosening the ribs, the gyro is fixed on the launcher, and then the gyro will rotate by lightly depressing the trigger with your index finger.
Metal gyro The gameplay is to use a cotton thread to wind the shaft in the middle of the gyro, then quickly pull it to rotate it, and then place it on a bracket. Degrees of rotation, so it is also called a radar gyroscope.
Heavy metal gyro This gyroscope plays the same way as the paper gyroscope, but the materials used are different.
Gyroscopes are still popular among friends for its varied gameplay. The gyroscope is not just as simple as a toy. Its importance is that scientists have developed a scientific instrument-gyroscope based on the mechanical characteristics of the gyroscope, which is widely used in scientific research, military technology and other fields. And there are quite a few types of gyroscopes. Here are some common gyroscopes.
Laser gyroscope: It is a more advanced gyroscope. Its principle is to use the frequency difference between two beams emitted by a ring laser to measure the angle and orientation. Laser gyroscopes are used for navigation and tracking of ships, airplanes, etc.
Fiber optic gyro: Fiber optic gyro is a new generation of gyro after laser gyro. Its principle is similar to that of laser gyro. Cost is lower. Countries are working hard to develop fiber optic gyroscopes. The gyroscope is mainly used to determine the angle (inclination), speed, and azimuth. According to different uses, gyroscopes can be divided into rate gyroscopes and gyroscopic inclinometers. The rate gyroscope is mainly used to measure the rotating speed of the measured object to calculate the corresponding data to achieve the purpose of measurement. Gyro inclinometer is used to measure borehole inclination and azimuth. It is mainly used in mining areas and oil fields.
Real-world applications
◆ Leisure
◆ Intellectual development: Germany and other countries design gyroscopes as educational supplies. The graphics cards are placed on the tops. Through the game of turning the tops, the patterns, colors, or numbers on the graphics cards are identified to train eyesight and concentration.
◆ Folk Sports
◆ Art creation: using different painted pigments and methods to show different local folk customs, the beauty of mixing when rotating can become a treasure of the collection.
◆ Scientific research
