Features

• Comparison of different methods to determine the elastic line: Virtual work, Mohr’s Analogy 
• Statically determinate and indeterminate systems 
• Various load cases: Point load or bending moment 

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 Tesca Determination of Elastic Line 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 realize 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. 
The well-structured instructional material sets out the fundamentals and provides a step-by-step  guide through the experiments.
