Bending of Beam: Uniaxial or Unsymmetrical Model MT 042

* Symmetrical and unsymmetrical bending on a beam1
* Symmetrical and unsymmetrical cross-sectional profiles: I, L and U1
* Combined bending and torsion loading by way of eccentric force application

Item Description

Bending of a beams 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.

Sci-tech Bending of Beams: Uniaxial or Unsymmetrical Model MT 042 is used to perform experiments relating to symmetrical and unsymmetrical bending and to combined bending and torsion loading.
