What Is an Example of a Block and Tackle Pulley?

Answer

A block and tackle pulley is a setup where two pulleys are attached together. To build one, you attach one pulley to a fixed object. Then you attach another pulley to the object you want to move, and run the rope through the second pulley. Finally, you attach the end of the rope to the same fixed object as the first pulley. This is an example of a block and tackle setup. It should reduce the amount of poundage you need to apply to the rope.
