Compound Machine

Our compound machine consisted of 3 simple machines, a gear and chain machine, a pulley machine, and a lever machine. Our compound machine runs on two motors and has a tank like tred design. The treds drive the bottom of a flat base that supports a large catapult. A pulley system is used on the side of the machine to lift objects onto the platform. Though this machine may have very little use today, it may have been able to be used in ancient times as a type of siege weapon.
