Hertzian Contact Apparatus- Engineering Lab Training Systems.
Technical Description This portable unit demonstrates the characteristics of the contact area in the case of Hertzian contact. A pressure pad made of rubber is pressed against a transparent plastic plate using a lever. Plate and pressure pad are convex. In this way both circular and also elliptical contact areas can be generated. The force on the lever is measured with the aid of a spring balance and the contact area is measured. This can be clearly seen as it is illuminated from the side by a halogen lamp.
