Creating Our Own Pulley System

Our task was to work in a group and create a pulley system with a fixed and movable pulley.

We used a spring scale to measure the amount of force it took to lift the movable pulley and the weight we attached to it. It took .95 Newtons of force to lift it. Then using the pulley system we used the spring scale again to measure the amount of force needed to lift the movable pulley and weight. It took only .4 Newtons to lift the weight. The mechanical advantage is 2:1.
