Why can't bows and arrows be left blank?

If it is empty, the energy stored in the bow deformation cannot be taken away by the kinetic energy of the arrow-that is why the weight of the arrow is also particular.

Bowstring is a material with low elongation, so the energy released by bowstring expansion is very small.

So basically all the energy stored in the bow is released on the bow piece.

A good modern bow, whether it is a compound bow or a flat bow, is basically laminated. Carbon fiber, glass fiber, sawdust and other different materials are combined in different ways and laminated together by bonding.

However, the strength of adhesives and materials may not be able to withstand the energy released instantly by air release.

Therefore, due to air release, degumming or the material itself is torn. ...
