Diamond's very high scratch resistance and thermal conductivity, combined with a lower coefficient of thermal expansion than Pyrex glass, a coefficient of friction close to that of Teflon ( Polytetrafluoroethylene ) and strong lipophilicity would make it a nearly ideal non-stick coating for cookware if large substrate areas could be coated economically.

The purpose of friction clutches is to connect a rotating member to one that is stationary, to bring it up to speed and to transmit power with little slippage.

Since the surfaces of a wet clutch can be slippery ( as with a motorcycle clutch bathed in engine oil ), stacking multiple clutch discs can compensate for the lower coefficient of friction and so eliminate slippage under power when fully engaged.

The electrical energy efficiency of a typical industrial induction motor can be improved by: 1 ) reducing the electrical losses in the stator windings ( e. g., by increasing the cross-sectional area of the conductor, improving the winding technique, and using materials with higher electrical conductivities, such as copper ), 2 ) reducing the electrical losses in the rotor coil or casting ( e. g., by using materials with higher electrical conductivities, such as copper ), 3 ) reducing magnetic losses by using better quality magnetic steel, 4 ) improving the aerodynamics of motors to reduce mechanical windage losses, 5 ) improving bearings to reduce friction losses, and 6 ) minimizing manufacturing tolerances.

This view was further elaborated by Belidor ( representation of rough surfaces with spherical asperities, 1737 ) and Leonhard Euler ( 1750 ) who derived the angle of repose of a weight on an inclined plane and first distinguished between static and kinetic friction ..

The effect of the time of repose was explained by Musschenbroek ( 1762 ) by considering the surfaces of fibrous materials, with fibers meshing together, which takes a finite time in which the friction increases.

The triboelectric effect ( also known as triboelectric charging ) is a type of contact electrification in which certain materials become electrically charged after they come into contact with another different material through friction.

For Knight ‘ picturesque ’ means simply ‘ after the manner of painting ’, a point which is important to his further discussion of sensation, which in Knight's view is central to the understanding of painting and music which are ‘ addressed to the organs of sight and hearing ’, while poetry and sculpture appeal ‘ entirely to the imagination and passions .’ The latter must be understood in terms of associations of ideas, while the former rely on the ‘ irritation ’ or friction of sensitive parts of the body.
