What is a mechanism that incorporates some kind of simple machine (e.g. a lever, wheel and axel, pulley, an inclined plane, a wedge, or screw); this mechanism must be within your register and ability to research and explain. Considering that you are required to describe a mechanism that is comprised of at least one simple machine, you must describe the mechanical advantage (MA) through mathematical formulas when you describe "theory" and function in the Introduction and/or Discussion, depending on whether the MA describes a part's function or the whole mechanism's. Therefore, you will need to research the type of simple machine as well as the physical principles at work when such a machine is incorporated into a mechanism. Then, write word report, which should include: a introduction,discussion and conclusion
