Why does a tumbler never fall? What is the secret of a tumbler?

I don't know if you have ever played with a tumbler? Friends who have played will find out how the tumbler is put and how to push it will not fall down. Why is this? What is the secret of the tumbler? Next, let's have a look with Sihai.

Why does a tumbler never fall? What is the secret of a tumbler?

We will find that no matter how you push the tumbler, it will not overturn. Even if you put it horizontally, it will still stand up. What is the reason for this?

Welcome to [Sihai wechat: www4hw]

Originally, the horizontal brick is very stable, but if you put it up, it is easy to overturn. This is because when the bricks are laid flat, the area contacting the ground is large, and most of the weight is concentrated at the bottom. In other words, the center of gravity of the brick is low when it is laid horizontally, so it is not easy to overturn.

The reason why the tumbler does not fall is: on the one hand, it is light and heavy at the top and heavy at the bottom, and its center of gravity is very low; on the other hand, its bottom surface is large and smooth. When it tilts to one side, the center of gravity and the contact point of the table top are not on the same plumb line, so it will swing under the action of gravity. Energy will be lost in the process of swing. When the energy is reduced to zero and the line of gravity just passes through the contact point, it will stop swinging.
