SE 110.47 Methods to Determine the Elastic Line Show data sheet (pdf file) Print page
Technical Description

Beams are key structural elements in mechanical engineering and in construction which are subject to deformation under load. In the case of a simple beam this deformation can be predicted by various methods, such as the principle of virtual work.

  The beam under investigation in SE 110.47 can be supported by different bearing methods. Two supports with clamp fixings and an articulated supports with a force measurement dial gauge are provided to realise statically determinate or indeterminate systems. The two supports with clamp fixings are provided with dial gauges and can also be used as articulated supports. These dial gauges enable the angle of inclination of the beam to be determined at the support. A third dial gauge records the deflection of the beam at a random point. A device is additionally provided to generate a bending moment at a random point on the beam. A fourth dial gauge records the angle of inclination of the device.

  The beam is placed under load by weights (point load and coupled forces to generate the bending moment). The clamping moment on the supports can be determined by means of weights.

    The various elements of the experiment are clearly laid-out and housed securely in a storage system. The complete experimental set-up is arranged in the frame SE 112.

  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
