A construction worker uses a hammer to drive a sharp nail into a concrete wall. What two simple machines is the construction worker using when he does this task-(D) a wedge and a lever

Wedges is also a form of simple machine and the inclined plane forms its foundation. A wedge can be referred to as the sharp edge of an inclined plane.They are used to level out a structure of an object
Thus we can say that A construction worker uses a hammer to drive a sharp nail into a concrete wall. What two simple machines is the construction worker using when he does this task-(D) a wedge and a lever
