Is the slingshot round or flat?

In order to provide a large tensile force, the flat rubber band should be made thick and wide, that is, the rubber cross-sectional area is very heavy, and it is also smart to make it round. Moreover, there are many binding methods, which are simple and practical.

Slingshot is a cold weapon or a game tool. Slingshot is generally made of branches in the shape of a "ya", with epithelial tendons at both ends of the upper end and a piece of skin wrapped in the body.

The power of flat leather slingshots;

The power depends on the initial velocity of the projectile, which is related to the kinetic energy given to the projectile by the rubber band, that is, the contraction distance and force when the rubber band contracts. The greater the stretch ratio of the rubber band, the greater the contraction force.

Therefore, the rubber band is very short. Although the stretch ratio is large, the acceleration distance is short. The rubber band is long, it can't be pulled in place, and its resilience is small. If you want to give full play to the potential of the rubber band in your hand, according to the length of the rubber band stretched by your arm, divided by the stretching limit of the rubber band is the best rubber band length.

Then put the bow when it is full. The longer you wait, the slower the rebound speed will be.
