The Pin Jointed Frameworks Apparatus mount onto two end supports. One support has a pivoting arrangement whilst the other has pivoting and rolling arrangement. Each framework member has a strain gauge arrangement attached. The signal from the loading mechanism and strain gauges is fed directly into the Interface. The loads on the Pin Jointed Frameworks Apparatus are applied at known joints by using the screwjack loading mechanism supplied.
The Pin Jointed Frameworks Apparatus enables students to assemble two Pin-Jointed Frameworks (warren and basic roof truss) to measure the strains (hence stresses) and joint deflections. Each member of the framework can be easily interconnected with each other by use of simple joints that are designed to create a truly pin joint.

It consists of support rod, single pulley, desk-side clamp, and small iron ring and nylon wire. It is used to prove that the standing pulley can’t save effort but can change direction; the movable pulley can save half of effort but can’t change direction of force. The height of support rod is adjustable.

The unit is supplied with manuals which describe all parts of the unit, the installation and utilization procedures, as well as many exercises with experimental results. The Computerized Air Water Heat Transfer Apparatus allows to perform several experiments relevant to the thermal exchange phenomena connected to convection and conduction and some interesting experiments on fluid dynamics. Moreover, the transducers and the dedicated software allows the data acquisition of the main thermodynamics quantities and to obtain or as a table or as a graph, the acquired values and the thermodynamic calculated quantities. In particular, it is possible to study the thermal exchange between a gas (air) and a liquid (water) and the thermal exchange between an air flow rate in a forced motion and a wall at different temperature.

This climate depends on different influences, such as the surface temperature of the evaporators, cold storage room temperature, degree of evaporator icing, quantity and type of refrigerated goods etc. Icing of the evaporators significantly reduces the refrigeration capacity and must therefore be prevented as much as possible by periodic defrosting, i.e. heating the evaporator surfaces. The climate in the cold storage room has a significant effect on the quality of the products stored there. The icing of the evaporators depends on the evaporator and room temperatures and the quantity of humidity introduced by the refrigerated goods. The evaporator surface can be heated from the outside by electric heating or from the inside by hot gas directly from the refrigerant compressor. In addition to the periodic defrosting at set times, there is defrosting performed as required by measuring the actual ice coating.
