We already know that torsional springs have a wide range of applications, so here's the problem! Why, exactly, should torsion springs be used in a wide range of applications? Here first small make up to introduce the principle of torsion spring.

In applications, the bottom portion of the torsional spring is often secured to another location, resulting in other components rotating around the center of the torsional spring. Once the other components begin to rotate around the center of the spring, the spring is rapidly pulling the other components back to their original positions. This creates a force of rotation, which changes the force of rotation into the required resistance. In this way, the torsional spring can store or release this energy in a static way to hold the device in place to achieve the desired result.

Of course, we can also find that the application is different, in which the number of torsional springs are also different, so this involves a lot of physical and mathematical knowledge. The number of turns required by the torsional spring is calculated by the amount of resistance required to hold the device. And, in the process of calculation, according to the actual requirements of the application to design the rotation direction of the torsional spring.
