Why doesn t the gyroscope fall, the mechanical principle that the gyroscope won t fall

**: When the spinning top rotates, it not only rotates around its own axis, but also makes a conical movement around a vertical axis. In other words, the top rotates around its axis on one side and "revolutions" around its vertical axis on the other.

The speed of the "rotation" of the spinning top around its own axis determines the size of the swing angle of the gyroscope. The slower the rotation, the greater the swing angle, and the worse the stability; The faster it rotates, the smaller the swing angle and therefore the better the stability. It's pretty much the same as people riding bicycles.

The difference is that one moves in a straight line and the other moves in a conical curve. When the gyroscope rotates at high speed, under the action of the gravitational couple, it does not fall over in the direction of the force couple, and the vertical axis of the fulcrum of the detour moves in a cone, which is the gyroscopic principle.

The physicist took out a spinning top, spun it on the ground, and began to whip it vigorously, and as the top spun faster and faster, the top swayed from side to side and refused to fall, even though it only had a pointed touch. This is known as the gyroscopic effect: a rotating object has the inertia to maintain the direction of its rotation (the direction of the axis of rotation).

The experiment of the gyroscope tells us that the high-speed rotating thing has a property, that is, it can keep the direction of the axis unchanged, and the stubbornness of the gyroscope is called the stability of the gyro. The spinning top always keeps its axis upwards after turning, and although its feet are very sharp, it does not fall.

This involves a principle of helical stability. The object remains in its original state of motion while rotating around the axis of symmetry. This thing is very similar to the law of cow 1.

There is a speed of rotation. Inertia.

Analysis: Principle 1: Moment of inertia, that is, rotation has the stability of silver.

Reason 2: friction, structure and working characteristics of gyroscope. Since the tip of the top is an approximate spherical shape, when the top is tilted in the A direction while rotating, the A side of the spherical surface of the tip will be in contact with the supporting surface, which will cause the tip of the gyroscope to move in the direction of the dumping.

Evidence: A long-legged gyro can rotate smoothly on a rough surface, but it will continue to bounce on a smooth glass surface to gain more friction, and if the glass surface is lubricated, it will not only not run smoothly but will be more difficult.

Experimental verification: A magnet is placed in the bowl of the superconductor as a supporting foot, and a spinning top is made of wood to rotate. Soon the top will be head down and feet up.
