The frame for load tests has been designed specifically for experiments in the fields of steelwork and civil engineering. Large components at a 1:1 scale are studied. The demands of modern, technically sophisticated designs require a solid understanding of the strength and deformation of components. Different load states can be simulated in load experiments and the reaction to the load recorded and analysed. This makes it possible to demonstrate the load bearing capacity of the design by means of experiment.
Features:
Specially designed for large components at a 1:1 scale.
Wide range of applications thanks to extensive accessories.
Load tests on components from steelwork and civil engineering.
Learning Objectives And Experiments:
Bending tests
Load tests
Together with the accessories
Compression tests.
The Plain Tube and Tube Bundle in Cross Flow accessory includes two clear plastic plates that are designed to fit the aperture in the Cross Flow Heat Exchanger duct. Using the single tube plate the active element may be used to investigate the variation in heat transfer, temperature difference and surface heat transfer variation with air stream velocity. An electrically heated cylindrical active element with an integral surface thermocouple is supplied which may be inserted in the apertures in each of the two plates. One plate has a single central hole and the other consists of a six row tube bank with a removable tube in the centre of each row.
Exeperimental Capabilities:
Determination of the mean surface heat transfer coefficient for cross flow heat exchangers with one to six rows.
Deduction of the relationship between Nusse lt, Reynolds and Prandtl Numbers for each of the six tube rows.
Steady state determination of heat transfer , temperature difference and surface heat transfer coefficient for a single tube in a transversely flowing air stream at speeds of up to 30m/s.

A bench mounted circular table with a central pin and 360º protractor has three pulleys on adjustable clamps round the edge.
The triangle of forces in equilibrium can be constructed and the resultant of two known forces can be found.
Conditions of equilibrium are obtained by centralising a small cord ring over the central pin with cords to load hangers where the loads and lines of action are variable.

ABS ASR Power Control System demonstration panel presents the working of the Automatic Brake Power System ABS and the Anti Slip Regulation System ASR in motor vehicles with the aid of a microprocessor controller.
The system allows measurement of the following signals:
The tension of four different rotational speed sensor
The characteristics of the tension from the sensors depending on the gap width for the specified rotation speed
The characteristics of the tension from the sensors depending on the rotational speed of the toothed ring.
The pressure value in the hydraulic circuits (in the brake master cylinder or after a correction made by the ABS/ASR system)
The depth of the amplitude modulation of the sensors signal being a result of the whipping of the toothed ring in the function of the gap width.
The controller can operate as a configurable PID controller and as a 2-point controller. In the latter case, as well as the setting of the reference variable, the hysteresis can also be pre-set. The recorder function provides continuous recording of controlled, manipulating and reference variables. The software ideally supports the experimentation and learning process of demonstration models. Its key features are the software controller and the recorder function. It plots responses to changes in the reference (e.g. step input) and disturbance variables. The controller included with each demonstration unit can also be used instead of the software controller. Measured values can be printed out and saved to data media. Connection to a PC is by a USB port. The supplied USB interface module provides an adequate number of analogue inputs and outputs, enabling even complex circuits, such as a cascade to be controlled. In this case, controlled, manipulating and reference variables can be plotted, displayed and saved by the program's recorder function.

Diaphragm Pump Learning System are used to transfer fluid that too viscous, corrosive, abrasive, or hot for other types of pumps, making it a perfect choice for moving food products such as peanut butter, ink for the print industry, and pulp, paper, and petroleum products. The Diaphragm Pump Learning System also explores how to adjust a diaphragm pump flow rate, how to select the right diaphragm pump for an application, and how to install, maintain, disassemble, and troubleshoot a diaphragm pump. The Diaphragm Pump Learning System explains the function, operation, application, and variety of diaphragm pumps.
The Diaphragm Pump Learning System features a foot-mounted, air-operated diaphragm pump, air regulator, air lubricator, pressure gauge, air muffler, and piping network. Peristaltic pumps, also known as tubing pumps, are used to transfer fluids that cannot come into contact with the working parts of the pump, either to avoid contamination of the fluid or because the fluid is too corrosive. These industrial-grade components will help to familiarize learners with actual mechanisms they work with on the job. This commitment to providing high quality components is why is the worlds leader in skills-based, interactive technical learning. After completion, learners can proceed to additional pumps like the Peristaltic Pump and Piston Pump. Piston pumps, also known as plunger pumps, are used to produce high pressure fluid flow of water, soaps and detergents.
