Amazing method of a cran’s body to complete the active table

This is a very frequent problem: we sat on a terrace, a bar or a restaurant Table Limps. We put papers and hats … but our drinks are still in danger of pouring.

This problem is very exciting, and even science to try to solve it had to interfere. Andre Martin It’s a French particle physicist ChernIn the early 2000s, the European Laboratory of Particle Physics in Geneva, Switzerland.

As Daily mailHe felt he was motivated to read the problem because he was tired Unstable laboratory tables, This is always a cup of coffee.

In an article published in the magazine Nature Ownership How to hold four feet on the floorOvarian Philip ballThe editor of the magazine, he wrote: “Again, Martin was turning the desk to search for a stable position.”

Its solution is simple: you need to turn the table. According to math, if you have a square table with legs in the corners, if supported in irregular soil, There will always be a way to touch the floor of the four legs.

Imagine you have a table, where all the legs (A, B, C and D) They have the same lengthBut due to the irregular site, the foot is in the air.

If you turn the table on the grounds, the legs A, B and C are kept on the floor all the time, when the table returns 90 degrees, lA Bata D is technically lower than soil levels.

So, at some intermediate point of the twist, Should touch the base ground of the foot DThis shows that you can always find a standard position. However, the surface of the table is no longer level.

This method is worth it if the problem is irregular soil, but the mathematicians do not know how to judge a problem on a stumbling table Because one of its legs is random. There you must definitely seek to put down an object.
