What is the function of a cam in a compound bow?

The cam in a compound bow plays a crucial role in enhancing the bow's performance by providing both power and a mechanical advantage during the draw. When the archer pulls back the string, the cam's design converts the linear motion into rotational motion, which optimally stores energy in the bow. This action enables the bow to generate greater arrow speed while requiring less physical effort from the archer, especially at full draw.

Furthermore, the cam system allows for a smoother draw cycle and can help with the let-off, reducing the holding weight at full draw. This not only enhances accuracy but also makes it easier for the archer to aim without fatiguing their muscles. Thus, the cam serves as a vital component that directly influences the shooting experience and overall effectiveness of the compound bow.
