Wheel and Axle: A wheel and axle has a big wheel and a small rod (axle)
                     in the center. When the wheel turns, the rod also turns. It helps to move or

                     lift things easily.

                       If a machine only had wheels and no axle, could it still move?



                     Wedge: A wedge is a simple machine that has a sharp edge. It is used to
                     cut, split or shape objects. For example, a knife cuts fruits and vegetables

                     and an axe splits wood.
