For this project, my group had to make a compound machine using at least 3 different simple machines, and calculate mechanical advantage (IMA) for each component, and AMA, IMA, and efficiency for the entire compound machine. We then presented how our machine worked in front of the class. I learned a lot about gears and their mechanical advantages, because I previously only had learned about the standard simple machines, and knew nothing about sprockets, chains, or gears in terms of AMA and IMA.
