Today, when I opened the tap to take a bath, a question came to my mind that why it is opening on the left side only. I thought it would be only with the tap, but when I opened all the other things in the house, including the bottle, there were other cans in the house, there was a nut in the door, everything was opening on the left side. Let us know why this happens. What is the scientific reason behind this.
why does everything open to the left
This whole matter is related to power. Actually, every opening and closing thing is connected with the grooves, which are called screw or thread in English. You know that it does not take much strength to open anything, but it takes a lot of strength to tighten something. Like tap tap, bottle cap or nut in a bolt, grooves are made in the same way, so that when you turn it to the left, it opens and when you turn it to the right, it closes.
understand in scientific language
You know there are not one but two bones between our elbow and wrist. One of which is called radius and the other is called ulna. That is, when we rotate the wrist to the left, it is technically called pronation. In this process of pronation, the pronator muscles of our hands work. Actually, the pronator muscles start only from the half of the bone named radius, so it is a bit weak. This is the reason why we turn something to the left to open it, because it takes more force than to close it.
In the same way, when you rotate your wrist to the right, during this the supinator muscles of our hand work, the supinator muscles are attached to the bone above the elbow, and when we rotate the wrist to the right, our supinator muscles work. muscle) and the muscles of the bicep from above, the force of both is felt simultaneously. Due to this, we are able to apply a lot of force while tightening anything, because we are rotating it to the right.
