Criteria For the compound machine project we had to figure out a solution to lift a textbook at least a foot three consecutive times. In order to accomplish this you have to use at least three mechanisms including a wedge, inclined plane, pulleys, lever, screw, and wheel and axle.

Major Takeaways When we first did this project I knew the basic concepts of simple machines from working with them in middle school, but now I can use them in every day needs if necessary. This in addition to the simple machine project I found that it is very useful to know the basics before you get to the more challenging parts.
