Why is this Flathead considered a compound machine?

A flathead can be considered a compound machine because it consists of multiple simple machines working together to perform a task. It typically combines elements such as levers and wedges, which help increase efficiency when driving screws or nails. The interaction of these components allows for greater mechanical advantage, making it easier to apply force and achieve the desired outcome. Overall, its design exemplifies how different simple machines can be integrated to create a more complex tool.
