Falling off? Not falling? --Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
The magnitude of frictional force between two objects sliding relative to each other is related to the pressure and friction coefficient between them. When the wooden stick comes into contact with the wheel, the friction coefficient remains basically unchanged, so the frictional force is only affected by pressure. When two wheels rotate inward at the same time, the wooden stick on top will not fall off. This is because once the wooden stick leans towards one side of the wheel, the pressure on that side will increase, and the frictional force will also increase accordingly. The direction of the frictional force is towards the center, which will force the wooden stick to return to the central equilibrium position.
