It consists of a shaft with a cup or a spur at the end that supports and propels the butt of the dart. The atlatl is held in one hand, gripped near the end farthest from the cup. A simple machine that exhibits mechanical advantage is called a mechanical advantage device - e.g.: • Lever: The beam shown is in static equilibrium around the fulcrum. This is due to the moment created by vector force "A" counterclockwise (moment A*a) being in equilibrium with the moment created by vector force "B" clockwise (moment B…
