In 1966, the British Government produced a study known as the Jost Report, which announced that 4% of the nation's GNP and 30% of energy production was lost due to this, prompting establishment of centers for tribology. Superlubricity, a total absence of it, can occur between crystals in dry, incommensurate contact, and has been observed in graphit
In 1966, the British Government produced a study known as the Jost Report, which announced that 4% of the nation's GNP and 30% of energy production was lost due to this, prompting establishment of centers for tribology. Superlubricity, a total absence of it, can occur between crystals in dry, incommensurate contact, and has been observed in graphite surfaces out of registry with each other. It does not depend on the speed, or on area of contact, but, as it is not a conservative force, it does depend on the path traveled.  FTP, name this force, equal to its namesake coefficient times the normal force between the two surfaces, and which has static, dynamic, and rolling varieties.
