Description
The experiment hardware fits onto a Structures Test Frame. Students apply various loads at set positions along the top of a simple ‘determinate’ three-pinned arched structure. They can also apply a uniformly distributed load (UDL). The structure has a pivot at one end and at the crown. The arch rolls against a load cell at the opposite end. The load cell connects to a Digital Force Display to measure and display the thrust reaction. The equipment includes a lead to connect the load cell to a Digital Force Display. The lecturer guide provides details of the equipment including sample experiment results. The student guide describes how to use the equipment and gives experiment procedures. For extra ‘virtual’ experiments, we can supply the optional Structures Software (STRS), 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 diff erent test specimens. This extends the student’s learning experience. For automatic data acquisition of your experiment results, we can supply the optional Automatic Data Acquisition Unit. Supplied as standard with the Structures Software that displays and logs your experiment results and gives the extra virtual experiments.
Learning outcomes
Studies of the:
