The central forces machine was made for King George III in 1762, just two years after he ascended the throne in 1760. It is the most intricate piece of apparatus that Adams made for the mechanics lectures and was intended to be used with the philosophical table.. It is the mechanism which provided whirling for a number of experiments, including the measurement of centripetal forces. It consists of two vertical axes on which can be mounted rods with detachable weights, which can be spun horizontally by turning a wheel.
