A suspension strut with a progressive spring has been used. Blowing or discharge of nitrogen into/out of thecompensation container changes the attenuation. In two-wheel vehicles, single-tube shock absorbers arefrequently used.
The following can be shown:
Compression by pressing on the suspension strut
Movement of the cutaway work piston with finned valves forthe pusher and tractor phase
Device to change the spring hardness by turning the steppedsleeve on the bottom of the suspension strut of adjusting nut
In the cutaway compensation container, the cutaway dividingpiston (rubber membrane), in which the gas cushion can be found, can be seen.

This instructional kit provides the necessary material for students to learn systematically how a hub and a shaft can be joined together in a professional way using feather keys. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises. We recommend that the exercises are carried out in a workshop, as all preparations such as filing, drilling, countersinking and tapping must be carried out in a correct and proper manner by the student.

A bench top frame of profiled aluminium, houses shafts which can be moved within the grooves of the profile. Understanding the basics of gear trains is important. Gear Train Demonstrator ensures this is done in a simple, visual and durable way. The profile grooves ensure the quick and easy release and securing of the shaft and hence component parts. The Gear Train Demonstrator are manufactured from durable plastic and all other components are industrial standard parts. Onto the shafts sis bearings and the gear components themselves. Rotation of the gear arrangements is done manually. The pitch circle diameters of the gears are visually shown also.
Experimental Capabilities:
Variation of operation between different transmissions
Efficiency of different transmission types
Accuracy of setting up of different gears
Gear ratios
Input and output ratios
Modulus of gears.
The Hybrid Vehicle Demonstrator includes a Hybrid engine, a battery and an Electronic Control Unit, several meters showing power flow between the units, a brake switch and a potentiometer mimicking the accelerator pedal. The system can also be used to show the effects of regenerative braking. Two models are available: a bench top version and a panel mounted version. The controls the system to show students how the power is routed in a hybrid depending on the State of Charge of the Battery, and to allow them to make measurements on the engine performance under different load conditions.

The auto-test ampoules contain a pre-measured amount of liquid reagent and easily fill with the correct volume of sample for simple and fast sample and reagent mixing. Minimize the risks of improper measurement and contamination with IV Chemistry Reagents, which are contained in self-filling vials. Use these reagents with the colorimeter to simplify sample preparation and tests. Each ampoule contains an Auto-ID barcode that is read by the colorimeter and used to automatically identify the test parameter and initiates the test.
Consistency and reproducibility improved with ampoules and an meter.

The practice kit provides the material necessary for students to systematically learn how components can be joined together in a professional way using pins. Both flat and cylindrical parts are pinned together. We recommend that the exercises are carried out in a workshop, as all preparations such as scribing, drilling, clamping, reaming and joining must be carried out in a correct and proper manner by the student. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.

N° 3 sets of deflectometers (without dial gauges)
....
The unit consists of three members, three node discs and a set of weights with a weight holder. Each member is formed by a longitudinally bar, a spring and a dial gauge. These bars can form numerous simple bar structures with different angles. The bar forces occurring during the exercises are measured by the deformation of the springs situated in the middle of the bar with the dial gauges.
The Unit for studying Forces in a Simple Bar Structure represents a simple bar structure that allows the measurement of bar forces and the comparison of the experimental results with the calculations and the graphical method.
The set of weights and a weight holder are used to apply external load in the upper disc of the simple bar structure.
The method of joints and the calculations are used to determine the bar forces in the different bar structure to compare with the experimental results.
The members are joined by three node discs such that the joints can move freely. Snap-locks allow to engage the bars in the discs. Two of the discs also form the support of the simple bar structure, it can move freely and is fixed to the section base of the unit.
