ASTR5 Bending Stress in a Beam

ASTR5 Bending Stress in a Beam


The experiment hardware is a T-beam that fits onto a Structures Test Frame (ASTR1, available separately).

Students adjust a load cell that bends the beam and, when connected to the optional Digital Force Display (ASTR1a, available separately), it measures the bending force (load). Strain gauges and a digital strain bridge measure the strains in the beam. Dummy strain gauges compensate for temperature variation and balance the strain bridges. The equipment includes a lead for connection to the Digital Force Display (ASTR1a, available separately).

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 that you do with the hardware. They also extend the choice of tests than 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 that displays and logs your experiment results and gives the extra virtual experiments.
