Michell Pad Apparatus
Description of Michell Pad Apparatus
The bench-mounting unit has an aluminium plate (pad) mounted above a continuous loop flat belt. The belt runs in an oil reservoir to provide a continuous supply of oil under the pad. This creates a pressurised film of oil between the pad and the belt.
A set of thirteen graduated tubes show the oil pressure across and along the film under the pad.
Included is a variable speed control to control the speed of the motor that turns the belt. Students vary the belt speed to find the relationship between sliding speed, oil viscosity and pressure distribution.
