Friction machine made for King george III by George Adams in 1762, Fleet Street, London.
George Adams made the frictio machine for King George III in 1762, just a few years after he ascended the throne in 1760. Adams referred to this machine when he began his section on motion in his accompanying Course on Mechanics. The machine shows that friction is due to weight acting on the moving parts, not the area in contact with them. When the spoked wheel was spun, it would turn 'more than the space of a mile', according to Adams. Alternatively a watch spring could make the wheel oscillate. Friction was provided using the small brass lever and the number of oscillations with and without friction compared.
