Wheel and Axle

     A wheel and axle is made from a wheel that turns on a center post.  The larger the wheel is, the less force will be needed to move the load.  There are two parts to this simple machine, the wheel and the center post called the axle.

     The force moves in the same direction as the load.  Notice that in the picture, the force pushes in the same direction that the skateboard is moving.
