Wheel and Axel

• One of the simple machines used in sixties playgrounds was the wheel and axel. It was used in such things the witch hat and merry go round.

Inclined plane/screw

• Slides in the sixties were made of metal, basic and inclined planes. Compared to the slides of today which can be molded into different shapes such as the screw.

Lever

• One example of a lever that has started to fade out from playgrounds today is the see saw. They are not used anymore today because kids were getting injured

Wedge

•One example of a wedge that was used back then and now is skateboard ramps. Its also considered a inclined plane.

Pulley

•Many playgrounds use a pulley in things such as the zipline. One example is the Bridgemill parks wire ziplines, that contain two pulleys in the handle
