Which side of the slingshot flat rubber band is installed upward?

When the slingshot flat rubber band is installed, the reverse side is upward, and the power of the flat rubber band mainly comes from the taper. That is to say, the greater the taper, the greater the power you exert, but this taper cannot be infinitely enlarged, because the power gained by the large taper is at the expense of the service life of the rubber band. That is to say, the greater the taper, the shorter the service life.

Flat rubber bands one by one, width 12 to 25 cm. Cutting it requires felt board, hob and triangular ruler for drawing. Once the operation is wrong, it will cost you a layer of skin. You need to play with a big saw, which improves the precision and accuracy of the attack, but the side effects are also obvious.

Principle analysis

It has good resilience and usually relies on long stroke (large stroke) to provide enough kinetic energy. But if the operation is not standardized, it may hit your hand. The power of flat rubber band mainly comes from taper. The greater the taper, the greater the driving force, but the service life of the rubber band is sacrificed.

Types of flat rubber bands: overhead bow, flying tiger bow, bucktooth bow, etc. The crystal thread is thin, and the tied rubber band head breaks faster than the amber belt because of repeated friction with the crystal thread. Amber ribbon is a new thing, not as abrasive as crystal thread.
