Simple Machines: Fixed and Moveable Pulleys Sign In or Register to add photos

In our investigation of simple machines we discussed both fixed and moveable pulleys. We used a vintage String Racer toy from my childhood as a zipline (retrojunk.com) to talk about moveable pulleys, and through K'NEX toys, we built in addition to many kinds of machines a block and tackle setup that helped us measure the mechanical advantage of using such a system.
