SV601 – Unsymmetrical Bending and Shear


SV601 – Unsymmetrical Bending and Shear

This experiment allows the experimental investigation of the deflection observed when a load is applied to unsymmetrical beams or bars as well as being able to assess the location of the shear centre of these beams.

The experiment has the following properties:

  • Three different bar section specimens
  • Up to 1000g of weight hangers to apply load to the specimens
  • Two digital indicators to measure total horizontal deflection



One of a range of Experiment Modules that fit onto the SV100 Structures Bench Mounted Frame. The product helps students understand symmetrical and non-symmetrical bending of three different beam profiles, including an equal angle section, ‘U’ section and ‘T’ section.

Three different beam specimens can be supported individually using a clamping mounting block. A horizontal load is applied to the ends of the specimens using the weight hanger applying load via the cord, routed around the pulleys.

The specimens use the same material, wall thickness and are of the same outside envelope dimension (12.7mm). As a result, the deflection of these different specimens can be compared and evaluated. The centre of rotation of the beam samples is located through the centroid of area of the cross section of each sample.

The kit is supplied with twin DTI mounts that allow two digital indicators to be positioned perpendicular to each other on the horizontal plane. This allows the total deflection components of the specimens under loading to be easily measured.

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