Compound Machine

Compound machine explained in an easy to understand way:

Imagine you're trying to carry a stack of groceries from your car to your kitchen in one trip. Just as you might use a combination of techniques—like balancing bags on your arms and using your foot to prop the door open—to make this task easier, a compound machine utilizes multiple simple machines to accomplish work more efficiently. In this scenario, balancing the bags represents levers, your foot acting as a doorstop is a wedge, and together they simplify the task just like a compound machine combines elements like levers and wedges to achieve a goal more effectively.
