How to match the deflection after intercepting the arrow

Simply put, the greater the number of pounds, the lower the deflection of the arrow, that is, the arrow should be hard; Small pounds are the opposite.

The definition of deflection in mechanics is that the linear displacement of the center of mass of a section along the direction perpendicular to the axis during bending deformation is called deflection, which is an index reflecting the toughness of an arrow. Specifically, it refers to the quantitative value of the deformation degree of the middle part of the arrow shaft caused by the rated force in a certain length. The greater the deflection, it proves that the greater the deformation, the softer the shaft, the smaller the value and the harder the arrow.

For example, an arrow deflected by 700 degrees is much softer than an arrow deflected by 350 degrees. This is actually very easy to understand. Just remember that deflection corresponds to the degree of deformation. Under the same stress, the greater the degree of deformation (deflection), the softer the arrow shaft.

Matching deflection has two main functions, one is to improve the accuracy, and the other is to ensure that the arrow is not damaged.

The number of pounds of the bow is inversely proportional to the deflection, and there is a certain law, that is, for every 5 pounds added, the deflection will decrease by 50. Next, the point.

There is a simple truth that everyone knows, a bamboo pole, the longer the pole, the easier it is to bend, and the shorter the pole, the less easy it is to bend. In fact, the arrow shaft is the same. Therefore, according to international practice (in fact, it is the practice of American imperialism), what we usually say about the deflection of the arrow shaft actually refers to the deflection of the arrow shaft under the length of 28 inches.

Basic information:

According to this law, we can also grasp the match between the deflection of the arrow and the bow we use by intercepting the arrow. If I have more than a dozen shafts with a deflection of 5 10, although my pulling force is 55kg, the pulling distance is only 26kg. Is there any way to match my bow with a softer shaft?

Also by intercepting arrows. I just need to cut the shaft to 27 inches, which is shorter than 28 inches 1 inch, and the deflection will be reduced from 5 10 to 460, which will match my bow.
