Deformation of Bars under Bending or Torsion

Technical Description:

Bending and torsion are typical loads to which components are subjected. The resultant stresses and deformations can lead to failure of the component. A number of different factors play a role in this, including the material, the cross-section of the bar, the clamping length and the method of bearing support. This investigates the influence of these factors on the deformation of a bar under bending load or torque. A set of test bars has been assembled so as to permit direct comparison of measurement results. The bar under investigation is fixed to two movable support blocks and loaded down by a weight. A dial gauge records the resulting deformation. The support blocks include clamping chucks to hold the torsion bars and bearings for the bars in the bend test. The bearings offer a range of clamping options, enabling statically determinate or indeterminate bearing supports to be investigated. The torque is applied by a device mounted on a support block. The point of load application to generate the bending moment is adjustable. The various elements of the experiment are clearly laid-out and housed securely in a storage system. The complete test setup is arranged on the frame. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
