Conclusions
In our experiment my belief is that the inclined plane was the easiest because the calculations were simple and easy, whereas the pulley was the most difficult because it required more thought. The input for the machine was 75 grams, which was the weight, and the output was 19.5 because the mechanical advantage was more than one. To improve the MA of the machine, we could have added a steeper incline, a longer lever, or more strings in the pulley.
