The inhabitants of Mammoth Island are trying to find the best method to lift their mammoths when a young Islander uses a simple machine called a pulley to get the job done. A pulley is a wheel that carries a rope, chain or cable on its rim and can be used alone or with other pulleys to lift heavy loads.
