Experimental Module Optical Elastohydrodynamics- Engineering Lab Training Systems.
Technical Description The set-up is operated together with the basic module . A steel sphere is pressed against the underside of a driven glass disc. The light from a reflected light microscope passes through the glass disc and the film of oil at the point of contact, it is then reflected from the surface of the steel sphere. The thickness of the film of lubricant is determined visually from the colours of the interference rings produced. The microscope is fitted to an adjustable x-y slide and has a focus adjustment. A defined load of up to 200N can be applied to the sphere via a lever.
