Pulleys
Pulleys are the basis of the modern machines we use every day.
Engineers harness the power of pulleys by designing processes and mechanisms that help us achieve difficult tasks.
Thousands of years ago, early engineers used pulleys to help with construction of structures of monumental proportions, such as aqueducts, monuments and even pyramids. Today, we use pulleys to perform a variety of useful everyday tasks like opening window blinds or operating a garage door.
