Rotating compound gyro is composed of several horizontally symmetric rotating gyros. The male axis is vertical, and the self-rotating axis is horizontal and self-rotating. The vector sum of revolution centrifugal force and rotation centrifugal force is weightless, that is, the revolution above is weightless, but on the contrary it is overweight.
The reason why the bicycle doesn't fall down is that it produces a lot of torque when turning. The principle of rotating gyro not falling down is the same as that of turning bicycle, but the difference is that rotating gyro reduces the weight and bicycle increases the weight. Generally speaking, moving in the balance of force, balancing in the movement.
I can't find it on the shelf. Why don't experts know? The problem of centrifugal force counteracting weight moment motion is very important, and no one has studied it! The oblique movement of celestial bodies shows the true soul of matter, the rotating gyro shows the true soul of matter, and the suspended gyro is the weightless gyro.
The precession revolution direction of gyro is consistent with the rotation direction of rotation, and the angular velocity direction of precession revolution and rotation is consistent with the inherent inevitability. My guess is that the angular velocity direction of revolution and rotation is the same as weightlessness, and the angular velocity direction of revolution and rotation is opposite to overweight.
