The crack influences the vibration behaviour of the shaft by changing its rigidity. Using suitable analysis software, this change can be registered and inspection of the machine organised in good time. In the experiment, the crack is simulated by an asymmetric flange joint. Cracks due to material fatigue are very dangerous for rotating machines. Early detection of any crack is therefore essential before permanent rupture and often fatal consequences can occur. The accessory set-up includes two shafts of different lengths: one short and one long. The short shaft simulates a protruding shaft end, and is loaded with the belt drive. Variable tightening of the flange bolts produces a temporary gaping of the butt joint, which closely approximates to the behaviour of a crack.

The cold section is of identical dimensions to the hot end and is water-cooled. Both the heated and cooled ends are each fitted with three thermo couples at 15mm intervals to measure the temperature gradients along the bars.
A small-scale accessory that allows experimental investigation of linear heat conduction and the measurement of the thermal conductivity of various solid conductors and insulators.
The hot end uses a nominal 65W heater (operating at 240v maximum), which is fitted with a high temperature limit switch. The power supplied to the heater is controlled and measured by the Heat Transfer Service Unit .

The Low Temperature Refrigeration Study Unit is an extremely easy-to use and functional unit able to permit the study of a low temperature refrigerating cycle through a simple compression refrigerating cycle. A front panel with mimic diagram and instrumentation allows to keep the most significant thermodynamic quantities under control, so facilitating the students understanding and the teachers task. The unit allows the study of this cycle and particularly the influence of the temperature of the body to be cooled. Moreover it is possible to evaluate the cycle performances, hence the heat exchange when the body temperature changes. The main characteristic of the Low Temperature Refrigeration Study Unit is that to enable the student to study the low temperature refrigerating cycles, hence the properties of the low temperature heat exchanges, particularly the non-stationary low temperature heat exchange, as a function of the temperature of the body to be cooled. The unit is supplied with a manual which describes the components, the installation and utilization procedures as well as many exercises with experimental results.

The Geothermal Flush Cart Learning System, which includes a mobile cart and a pump system, will cover flush cart set-up and operation to teach how to flush, purge, charge, and pressurize the geothermal system. It also covers introducing an anti-freeze additive to prevent pipes from freezing. Geothermal Flush Cart Learning System teaches how to purge debris and air from the geothermal loop and then charge it with a glycol/water solution. The Geothermal Flush Cart Learning System also includes world-class, highly interactive multimedia that will help learners to gain insight into the theoretical aspects of how the flush cart works and then allows them to follow along with step-by-step explanations of hands-on skills. Proper procedures for filling and pressurizing the system must be followed to avoid aerating the fluid being used to charge the system or this entrained air will lower system performance. Dirt and plastic pipe shavings can become trapped in geothermal systems during construction and must be purged to avoid damaging the system during operation.
