Children shoot arrows and talk about it.
The characteristics of archery technology are mainly manifested in the following aspects:
(1) has linear symmetry.
There are two kinds of linear symmetric forces in archery, one is the linear force that penetrates the torso of the player. This force can be divided into air support to the body and lower limb reaction to support. It is usually required that the line of force is perpendicular to the air. This force is very important to ensure the stability of the shooter's trunk when shooting. Another linearly symmetric force consists of the force of pulling the bow and pushing the bow. Among them, the thrust direction points to the bull's-eye, the force line is in the field of vision, and the force line of the bow force is opposite to its direction and acts on the same straight line. If this force is defined as a force, then the linear force penetrating the engine trunk is a vertical force. The force always faces the bull's-eye, perpendicular to the appearance of the target. In the process of archery, the vertical force line and the horizontal force line should always be symmetrical. A small asymmetry will directly affect the accuracy of archery.
(2) dynamic balance
This feature can be said to be one of the most remarkable features of archery. Someone once described this characteristic of archery as "stretching like silk". In fact, it is required that the force should be very soft, smooth and stable, the rate of change of the force should be kept constant, and the push-pull force is always in the process of dynamic balance. The movement should be delicate, just like pulling a steel wire, and it should be pulled evenly.
(3) Simplicity
In the process of archery, we should try our best to reduce the exertion. Because the greater the stress, the more complicated the stress will be, and it is difficult for the shooter to keep balance all the time. The greater the force on an object, the easier it is to change the force and the more difficult it is to keep the balance of the force. Therefore, if you want to keep balance in archery, you should try your best to finish this exercise. The simplicity of applying force also includes the application of inertial force. It is emphasized that the stress is simple, loose is loose, and tight is tight.
