Here’s a video we found from Bill Nye, the Science Guy, from Disney that explains how pulleys work called “Pulleys – Simple Machines”.  The video begins with animation, and then about 3:15 minutes into the video, Bill Nye, along with kids, explain how pulleys are used on cranes, tree houses, and even sails on boats!  Click here

Pulley systems can be used for a variety of applications.  Here’s a video that describes and demonstrates the mechanical advantage using a rope and pulleys for vehicle recovery, specifically pulling a truck out of the mud when you are all by yourself.  Click here

Here’s another video describing how to pull a vehicle by Perry McDonough, who demonstrates proper winching using the single line pull and snatch block methods.  Click here
