The acquired data is processed by evaluation software on a PC. The data acquisition system significantly enhances the possibilities offered by the assembly project. The two systems together form a state-of-the-art materials tester with data acquisition, suitable for a wide range of experiments. The fully assembled presents a real, fully functional data acquisition system for the measurement of pressure (forces) on, and changes in length of, a test specimen. All the necessary tools and aids, as well as comprehensive instructional material, are included. The assembly process includes the basic mechanical construction and wiring as per the circuit diagram.

The computerized version unit allows, thanks to the electronic transducers and suitable software, to display on personal computer and/or print the tables of results and diagrams of the various experiments. The Computerized Boiling Heat Transfer Apparatus has been designed to perform experiments concerning heat transfer due to convection in a boiling liquid (water). The second leg of the bridge is used to balance the nickel wire and is immersed in a cooling vessel filled with water. The unit is supplied with manuals that describe each component of the system, installation and utilization procedures, and gives many exercises. The unit consists of a vessel containing a quantity of water continuously stirred and heated by a nickel filament. Since this wire is a leg of an alternate current bridge, the temperature can be measured very accurately.

Test beams fit onto the backboard using a rigid clamp and knife-edge supports. Students apply loads at any position using hangers holding various masses. The experiment hardware consists of a backboard that fixes to the Multi Structures Test Frame.
The indicator measures beam deflection. Scales on the backboard show the position of the indicator, the loads and supports. Mounted on a trammel, a digital deflection indicator traverses the beam.
Features:
High-quality structures teaching module for students of mechanical, civil and structural engineering
For study of beam deflection under different loads and fixing conditions
Realistic and verifiable experiment results
Optional AII's Structures Software package for extra virtual experiments that simulate and confirm the results from your hardware and allow extended experiments
Allows safe and practical experiments into deflections of beams and cantilevers
Ideal for classroom demonstrations, or students working in pairs or small groups
Optional unit including AII's Structures Software package for automatic data acquisition and virtual experiments
One of many interchangeable experiment modules from AII's modern, flexible and cost-effective Structures teaching system.
Study high performance engines, as the engine allows for different compression ratios and timing to be selected, then Horsepower and Torque to be viewed on screen. The software package, is a powerful training aid for any student learning alternate fuels. Students can actually see which fuel produces more torque! Which burns hotter, propane or alcohol? Information like this can be graphed, and compared on a computer, then saved or printed. Graph multiple runs of the, using alternate fuels (propane, methanol, ethanol, etc.), showing the properties of each.
