Hertzian Contact Apparatus- Engineering Lab Training Systems Description and Specifications for Lab Tenders
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.
