Hertzian Contact Apparatus

Hertzian Contact Apparatus

•    The Hertzian Contact Apparatus is a self-contained and easy-to-use unit that shows the nature of contact between two surfaces.
•    It compares experiment results with predictions based on Hertz’s original theories.
•    A hand-operated hydraulic pump and cylinder force the two pads together.
•    Students may rotate the lower pad, a pointer shows the angle of rotation.
•    This allows a study of the effect of different relative curvatures.
•    The apparatus has two pads with curved contact surfaces. The upper pad has a compound radii.
•    The contact zone may be circular or elliptical, depending on the relative angular position of the two pads.
•    Supplied is a transparent scale to measure the contact shape and angle.
•    Locknuts on the threads of the pump work to limit the maximum pressure, preventing damage to the equipment.
