Polarizing filter, press and bending set

To demonstrate the tension distribution in elastic deformation in polarized light;
Use in combination with the polarization filter set DL401-3A (polariscope);
- Metal hood with slots for stable holding of the two polarizing filters,
- Wooden block (9 x 9 x 5 cm) with marking, for supporting the test bodies,
- Test body "beam" (10 x 2.5 cm) with two support angles, push rod with edge, L = 25 cm,
- Test body "crane hook" (L = 10 cm) with screw,
- hook with handle for generating tensile or compressive forces
