In our compound machine the Pulley was the easiest to determine the mechanical advantage of because you just had to count the strands. In our compound machine the incline plane was the hardest to determine the mechanical advantage because we had to measure it and then divide by the two lengths. The values where easy because we put less into the machine and got a lot more out of it. We got these values because all of the machines had a mechanical advantage of 1 or a little bit more than 1. To make the machine more efficient we could've made the incline plane steeper than the original.
