A traction catapult is powered by human muscles. Typically, it consists of a pole or lever arm that pivots. A person pulls down as hard as possible on the shorter end, which makes the longer end spin very fast. The fast-moving end is capable of shooting a projectile much farther and higher than a person could ever simply throw it.
