  Transmitted Light Polariscope

  Using this transmitted light polariscope, photoelastic experiments can be performed. This process exploits the fact that the refractive index of photoelastically sensitive materials changes under mechanical stress. Transmitted polarised light experiences a rotation of its plane of polarisation, this results in lines in the material subject to the same stress being of the same colour. The distribution of the stress in the model can thus be clearly seen. The polariscope can either generate coloured stress diagrams using white light or, using monochromatic light, light-dark diagrams. The filters, which have angular scales, can be rotated in a holder mounted on rollers. On the side is a pointer using which the angular position can be read off. Light sources, polarisation filters and load frames are separate components on this unit. Thus it is possible to realise flexible experimental set-ups also with own models.

  Bifilar Trifilar Suspension Apparatus

  The model permits oscillations on pendulums with bifilar or trifilar suspension to be investigated. For this purpose a bar, a cylinder, or a hollow cylinder made of galvanised steel can be hung from a wall mounted carrier plate made of aluminium and placed in oscillation. The bodies used in the experiments have strong steel hooks for attachment to the suspension cords. The length of the cords can be rapidly changed and securely fixed using clamping wheels. The beam can oscillate, by translation, in the plane of suspension like an ideal mathematical pendulum. The cylinder and the circular ring work as rotary pendulums.

  Shearing Force and Bending Moment Apparatus

  This demonstration unit facilitates the experimental investigation of the progression of the bending moment and shearing forces on a bar subject to point loads. In addition, the section principle commonly used in mechanics can be demonstrated. Due to the use of a low friction joint with two degrees of freedom at 1/3 of the span and two dynamometers, the measurements can be recorded directly from the bar. The deflection of the bar as result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. The bar is loaded with graduated sets of weights that can be attached at any point on the bar.
