9. Curiosities • A pulley is a simple machine used to transmit a force. It is a wheel, usually solid and grooved on its edge, which, in the course of a rope or cable that is passed through the canal (gullet), is used as a transmission element to change the direction of motion in machines and mechanisms.

10. Personal Comments • the pulley is a great invention because without it we would bear too much weight q and q she can do that is very easy. • because no one could evolve material was invented q new. • Work is a little bit difficult because it is in English. But I learned a lot about the pulley in this work.
