Description
Dr Stephen Demainbray (1710-1782), a famous science lecturer of the 18th century, 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.
