This allows students to create and study the effects ofbalanced or unbalanced capacitive loads. Each bank of capacitors includes athermally operated circuit-breaker to protect the loads. The Portable Capacitive Load Bank is a robust steelenclosure that contains three banks of switchable capacitive loads. Each bankof capacitors is electrically separate, so they can connect as a star or deltaload for three-phase circuits. This helps to preventelectrical shocks when the students disconnect the circuits. The value of thedischarge resistor is too high to affect any experiment results. Each bank has a set of switches to bring eachcapacitor into circuit. Each capacitor of theload bank includes a high-value discharge resistor that safely discharges anyd.c. electrical charge that remains after experiments. Studentsconnect the loads to experiment circuits using safety sockets on the enclosure frontpanel. The other loadbanks are Resistive and Inductive. The enclosure has ventilation holes and hascarrying handles for portability. Students can use this load bank in combination with the other similarload banks to provide variable power and power factor loads.

The dynamometers have been designed for low friction torque at the propeller shaft and for this reason shaft seals are not fitted. As a result, the dynamometers are not watertight. If watertight propeller dynamometers are required, alternative designs are available. All dynamometers have a similar appearance although vary in size / rating to suit the intended specification required. The Dynamometers are compact with low weight and small dimensions and as such are suitable for use with models over a wide range of sizes however also offer with suitable accessories the ability of mounting two dynamometers driven through a gear box to allow the testing of twin screw models. The self propulsion dynamometer measures thrust and torque of the propellers during propulsion tests with ship models on smooth water and in waves in towing tanks.

The Control and Instrumentation Study Station uses industry-standard parts to teach industrial process control. Two valves control the flow of the water supplies into a process vessel. Hot and cold water supplies connect to the study station. It is an excellent tool to help train plant technicians and process control engineers.
The process vessel has three jobs:
A pressure vessel with a pressure-relief valve for safety
A liquid-level reservoir with a sight gauge
A temperature-mixing chamber for the hot and cold water flows
Friction is the resistance of a body against movement on a base. Self-excited friction oscillations, also known as slipstick phenomenon, occur if the static friction is significantly higher than the dynamic friction. Static friction means that a body remains at rest under the action of a force. If a limit value is exceeded, the body begins to move on the base, resulting in dynamic friction.
Learning Objectives And Experiments:
Observation of the transition from static to dynamic friction
Together with the drive unit
Influence of the relative velocity of the friction partners on the slipstick phenomenon
Influence of the force between the friction partners on the slipstick phenomenon
Influence of lubrication on slipstick phenomenon.
Features;
Friction rings of different materials for the study of different friction pairings
Slip Stick phenomenon at the transition from static to dynamic friction.

The solar energy is captured by a cylindrical parabolic solar concentrator in which the parabola axis is constituted by a high thermal conductivity tube and black colour containing an adequate liquid able to capture the solar energy increasing its temperature. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle is one of the most interesting applications of solar thermal energy because it is able to use the solar energy and, via an absorption cycle, to convert the energy in a source of cold that can be used for food conservation chain, air conditioning, chilling water and in general in all the applications of refrigeration and conditioning purposes without the use of electrical energy. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle has been designed and manufactured by Italia to allow the experimental study of an absorption refrigeration plant using solar energy as energy source. Owing the peculiarity of the plant able to use the solar energy to convert it in a source of cold, the plant is particularly interesting in all the countries of the equatorial area, where the sun is the main energy source and the coverage of the electrical network is scarce.
