Features
Symmetrical and unsymmetrical bending on a beam
Symmetrical and unsymmetrical cross-sectional profiles: I, L and U
Combined bending and torsion loading by way of eccentric force application
Bending of a beam symmetrically - also known as uniaxial bending - occurs when the load plane coincides with one of the main axes of the beam cross-section. The beam then deflects in the direction of the load and can be described by elastic lines.
In unsymmetrical bending of a beam - also known as complex or biaxial bending - the main axes of the cross-section do not coincide with the direction of loading. To prevent torsion, the line of application of the load must pass through the shear centre. If it does not, the beam undergoes combined bending and torsion loading.
Tesca Bending of Beams: Uniaxial or Unsymmetrical is used to perform experiments relating to symmetrical and unsymmetrical bending and to combined bending and torsion loading. The beam under investigation is clamped into place on one end and loaded down by a set of weights at the free end. Two dial gauges  record  the  horizontal  and vertical deformation of the beam. The unit includes three beams with different cross-sectional profiles: I, L and U. The beam can be clamped with freedom to rotate in  any direction. This enables investigation of loading along the main axis or of the general load case. An angle scale at the clamping point indicates the angular position of the beam. It is possible to adjust the load application point eccentrically, so that purely unsymmetrical bending or combined bending and torsion loading is investigated.
The various elements of the experiment are clearly laid-out and housed securely in a storage system. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
