EULER BUCKLING OF A COLUMN

The experiment hardware fits onto a Structures Test Frame (STR1, available separately). Students compress aluminium columns (struts) using a screw mechanism. The equipment uses chucks to hold the struts and allows different endfixing conditions. An integral load cell connected to a Digital Force Display (STR1a, available separately) displays the load on the strut as it is compressed. A magnetic deflection scale shows how much the strut buckles. Students continue compressing the strut until reaching the critical buckling load. They then repeat the experiment using different strut lengths or fixing conditions, analysing their results.

The equipment includes strut storage space and five different sizes of aluminium strut.

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, TecQuipment can supply the optional TecQuipment 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 different test specimens. This extends the student’s learning experience.

For automatic data acquisition of your experiment results, TecQuipment can supply the optional Automatic Data Acquisition Unit (STR2000). Supplied as standard with the STR2000 is TecQuipment’s Structures Software that displays and logs your experiment results and gives the extra virtual experiments.

case study
Structural Mechanics Lab Birzeit University - Palestine

For many years Birzeit University has trusted TecQuipment to be their no.1 provider of engineering laboratory products to aid the teaching of Mechanical, Civil and Environmental Engineering courses. Knowing from personal experience that the equipment is built to last, and that they can rely heavily on local support from TecQuipment agent in Palestine backed up by the dedicated TecQuipment Customer Services team, it was the logical choice to choose TecQuipment once again for their new lab equipment.
