The mechanism able to transform circular movement into reciprocating movement. The unit is assembled in an anodized aluminum profile structure, with steel painted panel. It is made of aluminium and consists of a rotary element (graduated disk), called crank, connected to a rigid bar, called connecting rod. The rotation motion of a crank or crankshaft causes a rectilinear reciprocating motion of a piston or plunger. When rotating the crank, the connecting rod moves back and forward.
It is a reversible system through which the connecting rod can be displaced by turning the crank and the other way round. If the connecting rod generates the input motion (as a piston in a car's engine does), the crank is obliged to rotate.
This mechanism is a combination of an inversion of the slider-crank chain and slider block.
A set of thirteen graduated tubes show the oil pressure across and along the film under the pad. The bench-mounting unit has an aluminium plate (pad) mounted above a continuous loop flat belt. This creates a pressurised film of oil between the pad and the belt. The belt runs in an oil reservoir to provide a continuous supply of oil under the pad.
Students vary the belt speed to find the relationship between sliding speed, oil viscosity and pressure distribution. Included is a variable speed control to control the speed of the motor that turns the belt.
Experiments:
Pressure distributions in a tilting pad bearing.
The relationship between pressure and the film thickness at the trailing edge of the pad.
Influence of sliding speed and viscosity on the pressure distribution in the bearing and comparison with calculations based on Reynolds equation.

The heat and light sources, instruments, filters and plates are mounted on an aluminium track with graduated scale, which is designed to stand on the benchtop and connect to the Heat Transfer Service Unit without the need for tools.
A heat source with radiometer and a light source with light meter are used where appropriate to demonstrate the principles.
A small-scale accessory designed to introduce students to the basic laws of radiant heat transfer and radiant heat exchange.
The light source consists of a 40 Watt light bulb (operating at 24V DC maximum) mounted inside a housing with a glass diffuser.
The heat source consists of a flat circular plate 100mm in diameter which incorporates a 216 Watt electric heating element (operating at at 24V DC maximum).
A comprehensive instruction manual is supplied.
The unit consists of four different types of pumps namely-centrifugal, turbine, reciprocating and axial flow pump, a common storage tank, and measuring instruments. Each pump is driven by a motor dynamometer for measuring TRUE pump input power. Multi Pump Test Set, Motor Dynamometer is a self contained set for studying the characteristics for various types of pumps. Speed control is by an inverter. The unit is floor standing with removeable supports. By manipulating flow control valves and a selector switch, each pump can be operated individually.
