Description

The experiment hardware fits onto a Test Frame. Students rest a beam on up to three supports. The supports are movable, so students can arrange them in many different positions under the beam. Students use masses on weight hangers to load the beam. The each supports contain a load cell to measure vertical reactions. These connect to a Digital Force Display unit. Two of the load cells have sinking knife-edge supports, which students can either fix or allow to sink by a set displacement. The third support load cell allows students to either clamp the beam (encastré fixing) or rest the beam on a knife edge. The unique design of this equipment allows the load cell to resist the bending moment while accurately measuring the vertical reaction.

The manual provides details of the equipment including sample experiment results and also describes how to use the equipment and gives experiment procedures.

For extra ‘virtual’ experiments, company can supply the optional Software for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware. They also extend the choice of tests beyond that available using only the hardware, for example: higher loads, uniform loads or different test specimens. This extends the student’s learning experience.

For automatic data acquisition of your experiment results, company can supply the optional Automatic Data Acquisition Unit. Supplied as standard with the Software that displays and logs your experiment results and gives the extra virtual experiments (optional).
