Mechanical linkages are made up of a series of levers which are connected together.
Linkages can change the direction of a movement, alter the size of a force or make things move in a particular way.
Parallel Motion Linkages are used to make two or more parts of a mechanism move together and stay parallel to each other as the linkage moves.
Bees
This model has three bees attached to a platform that rotates freely round a central pole. As the bees are rotated, the platform is forced to rise as the red strings twist and tighten themselves around the pole.
The bees are then released and the weight of the platform then makes the strings unwind, lowering the platform and starting the process all over again.
