Yesterday we talked about the flying grass and the cap on the mouth of the bottle, and I thought about water and buoyancy. Put the basin in the bookcase, add water to the basin and it will sink. However, I wonder if the outer ring of the basin is large, can it increase the buoyancy? In other words, buoyancy is determined by the area of the outer ring. If it has a second vertical outer ring, is it subject to greater buoyancy than the first vertical outer ring? Let's express your opinions on this according to your own thoughts. Mizukawa finally mentioned yesterday's incident.

We know that if the basin is empty, it certainly cannot float on the surface of the water with the first horizontal circle as the base. Because the shape of the basin determines how it is placed on the water. In general, the smallest face of an object is not possible on the surface of the water as its underside. However, if the surface of the water is stationary, the smallest surface can be used as the bottom surface. However, the surface of the water cannot be stationary. So, is it okay with the other sides? Actually, it's not okay. The underside of the object must be the fractal of the largest face. For example, a beverage bottle has three sides, with the largest sides. However, it is not possible for the sides to be in full contact with the water surface. So, the bottom surface can only be a fractal on the side. However, adding water to the first layer of space can solve this problem perfectly. Liuzi Fenglai said.

Not exactly. The bucket is placed in the water, and the smallest surface is the bottom surface. The reason is simple, the barrel does not have a lid.

The buoyancy of the first layer of space and the buoyancy of the second layer cancel each other out. When water is added, the buoyancy of the second layer increases. When the first layer of space is filled, the buoyancy of the second layer of space is greater than that of the first layer. If the basin has a third vertical outer ring, then the water must fill the second layer before it can stand on the water. Dueñas gave a brief explanation based on his own observations and analysis.

I think the area of each horizontal outer ring should be greater than the area of each vertical outer ring, because the buoyancy is horizontal, and only the horizontal outer ring area is larger, and the basin can get more buoyancy. However, the buoyancy of each layer is concentrated at the interface. In long-term use, problems may arise.

Buoyancy is related to the area of the water surface and the depth of the water body, and they work together to act on buoyancy. The larger the water surface, the less the basin will fluctuate. In order to prevent water from entering the basin, the top outer ring must be at an angle of 45 degrees to the water level. Margarita also said some.

Because water is fluid, it can lead to edge effects. That is, it has a flip to the limit. Once in an area outside the limit, the basin will flip. The boat is fully curved type, and this shape can greatly increase the flip to the limit. Therefore, from a practical point of view, it is flawed. Since the outer rings are all rounded, this is easy to spin. The shape of the ship avoids this.

There are always a lot of details, and maybe a lot of things we didn't think about. However, today's discussion inspires me. Everything should be looked at in a dialectical way, and then a relatively objective conclusion should be drawn. In order to have a good idea, I recommend that you read more books on physics and mathematics. Maybe we thought of something that our predecessors had already thought of, or maybe there were things they didn't think of. Either way, it can enhance our knowledge and horizons. Mizukawa said in the end.
