Overhead Polariscope- Engineering Lab Training Systems.
Technical Description
This transmitted light polariscope
facilitates familiarisation with the basic principles of photoelasticity
and the performance of stress experiments on plastic models. The unit
has two high quality circular polarisation filters that are held between
glass discs such that they are not placed under load. The filters in
the frame can be rotated horizontally as required, their optical axes
are marked with appropriate symbols. Eight different shaped load models
are included. Forces can be applied to the models using a loading device
equipped with a ring dynamometer. The coloured stress lines in the
objects that are a direct consequence of this loading can be observed
directly in the projection. The system includes a green filter for
monochromatic display. The experimental set-up is placed on a normal
commercially available overhead projector and does not require any other
accessories for operation
