Inclined plane, maker unknown, before 1753. Once belonged to Stephen Demainbray.

This inclined plane once belonged to Stephen Demainbray and was used by him in his lectures on natural philosophy. He used it with model carts to showi the advantage of large wheel diameters. Various shaped blocks were also rolled down the plane to demonstrate centres of gravity. The inclination could be altered by means of a screw in the base. Demainbray worked as superintendent at the King's observatory at Kew from 1768 and his collection of instruments and apparatus was absorbed into the King's own collection.

Inclined plane, before 1753. Dr. Stephen Demainbray (1710-1782), a lecturer on experimental philosophy, used the inclined plane in experiments with model carts, showing the advantage of large wheel diameters. Various shaped blocks were also rolled down the plane to demonstrate centres of gravity. The inclination could be altered by means of a screw in the base.
