Mizukawa brought a chair and said, "What do you think is the upload limit?"

Liuzifeng: We know that the chair has an empty body, and the actual loading capacity is definitely weaker than that of a non-empty body. I guess the loading force of a non-empty body is related to its volume, but what about an empty body? There is an empty body that seems to have no volume? Of course, the volume here does not refer to the actual volume, but to the empty volume. What is a cross-cut volume? It is the volume of the geometry delineated by the three legs of the chair connected in pairs, but should it be connected straight or curved? To know the loading limit of the chair, it is necessary to know its blank volume. However, this does not end there. Because the relationship between the crossover volume and the loading force is uncertain, it still needs to be discussed. Of course, the material of the chair will also have an impact on its loading capacity.

Because the chair is designed for people, the upload limit is not too large. I guess it's 1,000 cows.

Instead, Dueñas said: You have overlooked a problem. The load is sometimes stationary and sometimes in motion. For static loads, the load body is not demanding because it does not move. In general, the load system is more stable. If it is a static load, it can be measured according to the method of the six winds, and the moving load is a different matter. Motion loads can be divided into falling loads and original loads. The falling load requires the load body to have a great hardness, so the hardness of the load body determines its loading limit. If the load is falling, the load force of the load body is extremely low. If the load is original, it can be divided into fixed type and non-fixed type. When the load is fixed, the loading force of the load body will be reduced by a part. However, it still has a lot of load capacity. When the load is non-fixed, its loading force is lower than that of the load. In summary, solving the loading limit of the load body is the type of load that needs to be considered. The limits are different depending on the load. Therefore, there is no one uniform answer.

Margarita saw the situation and said, "It depends on how the load is placed." For example, mineral water bottles. You can put about six bottles in a standing position, but you can put up to two bottles when you fall down. For example, books. You can put a dozen to twenty copies when you put them flat, and you can put up to three copies when you stand them. Of course, it all comes down to the shape of the load at play. We usually sit on it, but our feet are on the ground. So, the ground shares a part of the gravity of people. Suppose the average human weight is 70 kilograms, and the acceleration due to gravity is 10 N per kilogram. Therefore, the average gravity of a person is 700 Ox. If the ground is divided into 260 N, the chair will have to bear 440 N. of gravity. Since the chair is not completely deformed, the gravity does not exceed its loading limit. Based on this, I deduced that the loading limit of the chair was 500 N.

Mizukawa smiled: There is one issue that everyone ignores, and that is time. It might be said that the upload limit is divided into the gravity limit and the time limit. In general, as long as the load does not exceed the gravitational limit, the time limit is not exceeded. The reverse is also true. When the gravity of the load exceeds the gravitational limit, the time limit of the load on the load body is very short. In other words, the load body can withstand gravity beyond the gravitational limit, but for a short time. Similarly, although the load does not exceed the gravitational limit, the load stays on the load body for a long time and causes fatigue. That's right, objects also get tired. Of course, this does not mean that fatigue is necessarily dangerous. There is a permissible range of fatigue here, which is determined by the amount of gravity of the object. Once this range is exceeded, the load body becomes fatigued. This fatigue causes it to deform and eventually lose its loading force completely or partially.

I really hope that there will be more and more such verbal encounters, and that we will get closer to the truth. I know you've reached the point of fatigue, so let's start recuperating!
