Conclusion: The easiest mechanism for mechanical advantage for me it was the lever because it is more simple than the other ones and easier to understand. The hardest mechanism for mechanical advantage for me was the pulley due to the weight and angle we had it at made it for me harder to understand. The input was 75 and the output was 19.5 approximately leading to the MA being more than 1, we figured this out through our equation and measurements. For modification on the machine I would like if we made the whole thing larger so weren't so cramped in that little space and also add more weight and maybe add more pulleys to add time on the machine so its more understandable.
