    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.

                         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.
