A self-contained product that shows how a self-acting gas lubricated journal bearing works. It also shows the onset of whirl. A hand operated load control and load cell allow the user to apply and measure the load on the bearing bush. The bush has pressure tappings equally spaced around its circumference.
The shaft has a high-quality surface finish and spins inside a vertically loaded bush. The main part has a variable speed motor that turns a belt drive. The belt drive turns a precision bearing shaft. The tappings connect to a multi channel digital pressure display unit.
Experiments:
Demonstrate how bearing speed and therefore compressibility number affects the pressure distribution in the bearing, and how this compares with theory.
Demonstrate how a vertical load affects the pressure distribution around an air-lubricated journal bearing.
Demonstrate the onset of whirl.

It comprises the calorimeter, a calorimeter vessel, an outer double walled water vessel, electric stirrer gear, combined motor control gear and ignition unit, a Beckman type thermometer, and a charging unit with pressure gauges to facilitate the charging of the calorimeter with oxygen. The equipment is self-contained with the control unit housed in an instrument case that forms the base. A Briquetting Press is available as an optional extra and an additional calorimeter can also be supplied. No spanners are required and in use the rubber joint is protected by water so it may be used over and over again. The particular features of the calorimeter are the method of sealing and the method of ensuring ignition. The body of the calorimeter is screwed into the base and a seal is made with a special rubber joint when the two parts are finger-tight only. In order to make ignition 100% sure, great care has been devoted to the method of anchoring the ignition wire and maintaining electrical contact and to the support of the crucible. All these parts are made to a high degree of precision and the results are very satisfactory.
....A heat exchanger coil is built into the reservoir such that the water temperature within the reservoir can be controlled by allowing cooler mains water to flow through the heat exchanger coil. This experiment includes a shallow heat collection tray approximately 1.2 m by 1m, the base of which is fitted with removable heat capture material. Water is pumped through the heat transfer plate, on the tray, and is returned to an insulated reservoir mounted on the base of the unit The water is continuously re-circulated through the transfer plate so that the temperature in the reservoir gradually builds up. An inclinometer to indicate the degree of tilt is available as an optional extra. This material assists in the heat transfer process. The heat capture and transfer plate is itself covered by a sheet of flat plate glass, which captures the radiation and reflects light back to the heat.

Reversible Pendulum Apparatus can be suspended from either pivot and swung. The two pivots are adjustable on the rigid metal bar and this allows the periods of swing to be adjustable. The Reversible Pendulum Apparatus consists of a rigid metal bar with two pivot points, one near each end of the bar.
The movable pivot is adjusted until the two periods are equal. From the period and the measured distance between the pivots, the acceleration of gravity can be calculated with great precision. In use, it is swung from one pivot, and the period timed, and then turned upside down and swung from the other pivot, and the period timed. At this point the period is equal to the period of an ideal simple pendulum of length equal to the distance between the pivots.

To find the acceleration due to gravity 'g'
Investigate the effect of fulcrum position.
