The secret of the ‘hole’ made in the chair, which is hardly known to anyone other than engineers!

We have all seen plastic chairs in our life – in weddings, in the courtyard of the house, on the roadside dhabas, almost everywhere. They are light, inexpensive and durable. But have you ever thought by sitting on these chairs, why is a hole made on their back or sitting place?

Most people think that it probably acts like a handle to lift the chair, or it is just a design. Some people also say that this air happens to pass. These things are somewhat correct to some extent, but the real reason behind it is a great example of science and engineering.

This is not a modest hole, it is a jugaad to break the ‘vacuum’!

The biggest feature of plastic chairs is that they can be easily stored in less space by placing one over one. It is here that that small hole does its biggest and most important thing.

Imagine, if there is no hole in the chair. When you place another chair above one chair, the air between the two will come out and an airtight seal will be formed. Inside Vacuum Or Air Pressure It will be born, just as two wet glasses stick together.

Due to this vacuum, it will be almost impossible to separate these chairs from each other. You have to put a lot of strength. That small hole is a solution to this problem. It allows the air to pass easily, which does not make a vacuum and you can easily keep the chairs one above one and can separate them without any hard work.

This hole also protects the chair from breaking

Another big benefit of this is related to the process of making the chair. When these chairs are made from molding process, this hole helps spread equally to plastic. If this hole is not there, then the back of the chair may weaken and due to overweight, the risk of its breakdown increases. This hole strengthens the structure of the chair, that too without using extra plastic.

There are other small benefits

Apart from the main reasons mentioned above, this hole has some other advantages:

• Yes, you can easily pull or lift the chair by holding it.
• If the chair remains out in the rain, then the water comes out of this hole and does not accumulate on the seat.

So next time you sit on a plastic chair, remember that the small hole on his back is not just a design, but a very thoughtful and clever engineering, which makes our everyday life easier.
