Description:

This annotated image from the American Physical Society presents the results of an experiment in which small photoelastic disks on a tray are squeezed in one direction and expanded in the perpendicular direction. The site includes images made using crossed polarizers, and the birefringence of the discs reveals the forces inside them. The site includes two images, a video, and a brief description of the experiment.
