The Alternator Synchronous Motor Learning System includes capacitive load, combination synchronous motor alternator, and synchronizing lights switch unit. The capacitive load unit combines with the Alternator Synchronous Motor Learning System to provide operation under various types of loads. Alternator Synchronous Motor Learning System adds to the Electric Machines Learning System to teach alternators and synchronous motors commonly found in industrial applications. Alternators provide a mobile source of AC electrical power while synchronous motors reduce power costs by correcting the overall power factor in a plant. The curriculum covers major topical areas such as alternator output voltage and frequency, three dark synchronization method, and reversing a synchronous motor. This system also offers curriculum in an optional, highly interactive multimedia format. Learners study industry-relevant skills including how to operate, install, and analyze the performance of alternators and synchronous motors. In addition to industrial components, includes in-depth curriculum, instructor guide, and student reference guide.

Compressed air is often used instead of electrical energy, particularly in workplaces where there is a risk of explosion of combustible gases. The heat generated by compression is dissipated by cooling fins. Compressors are at the core of compressed air generator plants. These plants are used where compressed air is used as a source of energy. The compressor is driven by a V-belt. This enables references to be made between individual components and the Large-format drawings suitable for workshop practice can be attached to the display board at the rear of the trolley. A second fully functional compressor, permanently mounted to the workbench, can be used for demonstration purposes. A disassembled piston compressor is contained in the drawers of the trolley cabinet which also holds the tools and assembly aids, small parts and gaskets required for assembly.

The changes of the resistance are particularly significant on the palm of the hands and on the plant of the feet. Such resistance decreases during periods of emotional stress. Moreover, the surface of the skin shows an electrical potential, that can reach up to 50mV and that can equally be influenced by emotional states. At the passage of an electrical current, the skin shows a resistance that is normally within the 100 kOhm to 1 MOhm range.

Typical circuit that is used in the monitoring of the Galvanic Skin Resistance
Variation of the resistance in direct current of the skin with relation to humidity

The three Spur Gear Lifting Machine supplied include a driver having 40 teeth, a driven wheel with 120 teeth and an intermediate gear of 40/120 teeth compound. The pulleys mounted to some of the gears can be used for either single or double purchase experiments. A vertical stand incorporates a back plate which carries a number of spur gears on shafts to enable single, double or three stage gear trains to be assembled.

A bench mounted base supports a variety of Curved Bars Apparatus in the form of a ring, semi-circle or quadrant/davit. Loads are applied by specially designed weight hangers so that the specimen bends. The theoretical deflections of curved shapes are most easily found by applying strain energy ideas, such as Castigliano's first theorem. The shapes chosen in Curved Bars Apparatus provide a relatively easy introduction to the use of such techniques. Horizontal and vertical deflections are measured by dial gauges rigidly attached to the base and surrounding pillars. All specimens, weight hangers and a set of calibrated weights are supplied. The Curved Bars Apparatus can be readily changed and the position of the dial gauges relocated to measure the deflections of the new configuration.
Experimental Capabilities:
To compare with theoretical estimates using strain energy theories such as Castigliano's first theorem.
To experimentally determine the vertical and horizontal deflections of various Curved Bars whose cross sectional dimensions are small compared with the bar radius.
