ASTR6 Torsion of Circular Sections

ASTR6 Torsion of Circular Sections


The experiments hardware fits onto a Structures Test Frame (ASTR1, available separately). It examines the behaviour in the elastic region of solid and tubular-section specimens.

Two chucks on a backboard hold a test specimen. A mechanism on one chuck applies torque manually to the specimen. A protractor scale on this chuck measures angular movement. A load cell on the other chuck measures torque. The equipment includes a lead to connect the load cell to a Digital Force Display (ASTR1a, available separately). To vary the test length of a specimen, one chuck can traverse the backboard. Included is an electronic angular transducer for use with the optional Automatic Data Acquisition Unit (ASTR2000).

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, AII can supply the optional AII Structures Software (ASTRS), 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, AII can supply the optional Automatic Data Acquisition Unit (ASTR2000). Supplied as standard with the ASTR2000 is AII Structures Software which displays and logs your experiment results and gives the extra virtual experiments.
