Photoelasticity

EXPERIMENT: PHOTOELASTICITY
1. Objective:The objectives of this experiment are
1. To introduce a very fundamental and most important experimental technique to view the principal stress components and directions of principal stresses- the photoelastic method.
2. To use the photoelastic technique for the direct measurement of principal stresses for the plane stress condition at any given point in the sample.
3. To view the map of principal directions at any given point in the sample.

I thought the monochromatic light source is a sodium vapour lamp emitting light of wavelength approximately 589 nm. But it was mentioned in the video that it is a halogen lamp, which is quite different. Kindly correct me if I am wrong.

Very nice video

Good morning sir, I request you to explain the complete experiment by demonstrating the setting of quarter-wave plates, explanation about isoclinics , isochramatics and finally how to count the fringes.

why not zoom to show his cells or atoms in the machine😂🤣😂
