A pulley is a wheel with a groove that turns on an axis. Let's see how it works in this video. https://www.youtube.com/watch?v=s9yJFtQ876E

Mechanisms allow objects to move. They make work easier and more comfortable for human beings. Let's see some examples:   Gears [youtube https://www.youtube.com/watch?v=Je0kOq48MDA?version=3&rel=1&fs=1&autohide=2&showsearch=0&showinfo=1&iv_load_policy=1&wmode=transparent] [youtube https://www.youtube.com/watch?v=o-Kdj_f6WCQ?version=3&rel=1&fs=1&autohide=2&showsearch=0&showinfo=1&iv_load_policy=1&wmode=transparent]   Sprockets with chains [youtube https://www.youtube.com/watch?v=32IAC8ZisPo?version=3&rel=1&fs=1&autohide=2&showsearch=0&showinfo=1&iv_load_policy=1&wmode=transparent]   Fixed pulley, movable pulley and compund pulley systems [youtube https://www.youtube.com/watch?v=DoRjsJRNGn8?version=3&rel=1&fs=1&autohide=2&showsearch=0&showinfo=1&iv_load_policy=1&wmode=transparent]   Endless screw [youtube https://www.youtube.com/watch?v=7rZ1ZW253Y4?version=3...
