Photoelasticity

Photoelasticity is used to determine the stress distribution in birefringent plastics, such as polycarbonate. This experiment uses the clear polycarbonate beams from the PASCO Structures System. Two crossed polarizing sheets are placed in front of, and behind, the clear beam. When illuminated from behind by a bright white light, fringes become visible.
