SV602 – Torsion of Rods and Tubes


SV602 – Torsion of Rods and Tubes

The experiment torsion of rods and tubes allows the experimental investigation of the torsional differences between specimens of various material properties under different load conditions.

This experiment has the following properties:

  • Torsion specimens secured between 2 chucks fixed to a pair of supports
  • Inclinometers to measure angular displacement of rod specimens at varying torsional loads, effective lengths and cross-sectional areas


One of a range of Experiment Modules that fit onto the SV100 Structures Bench Mounted Frame.

Two chucks supported by mounts on the Universal Frame hold a test mechanism. A torsion drive wheel secured to one of the chucks manually applies a torque to the specimen.

Three inclinometers positioned at equal distances along the effective length of the test specimen measure the angular displacement at that point along the specimen. In order to vary the effective length of a specimen, one of the chuck supports can laterally traverse the Universal Frame.

Results can be manual added to the supplied software for further analysis.
