How Does A Compound Bow Work Animation

Instead the string and harnesses pull the limb tips toward each other.

How does a compound bow work animation. As you can see in the video theres a lot more vibrations than what you might expect. Click on the following link to learn more. Heres how a compound bow works. The goal of these components is to decrease the amount of weight the archer holds at full draw thus making aiming much easier.

This was a project from junior year of high school and the video did not include physics i covered the physics aspects in an in class presentation. This is a slow motion shot of the cam on a compound hunting bow. Specially designed cam pulleys are used by compound bows to acquire the advantage of a decreased drawing weight at the end of the draw. As mentioned part of the challenge of traditional archery is to control a steady aim while holding the maximum draw weight.

The big wheels on the ends of a compound bow are cams and their profile is designed to create a let off at the end of the draw. With a compound bow the limb tips arent flexed backward toward the shooter by the string like they are with a traditional recurve that has no cams. The simple answer is that a compound bow works by allowing you to draw a bowstring attached to a pulley system of cables and cams which exert force on the limbs. Typically this is between 60 and 80 percent of the draw weight.

A compound bow is any bow that incorporates cams cables andor a pulley system on the bow. This makes it easier for an archer to hold a draw for an extended period. These pulleys have an asymmetrical shape and they are usually positioned at the tip of the limbs.
