Photoelasticity Bridge

Photoelasticity Bridge

Photoelasticity is used to determine the distribution of stress in a material. It is commonly used when the mathematical solutions get tricky or overly complex. We wanted a STEM based exhibit that would be hands on to allow children to explore the stress distribution of bridges.

Exhibits Intended Use

With our STEM exhibit children can explore how different weight along the sections of a bridge structure changes the stress points of the bridge. While at your science center, children can select from multiple styles of bridges (Truss, Suspension, Arc, etc), place it between the light source and polarizer and then apply pressure by hand on a sliding rig, thus changing the stress points as they move along the bridge exhibit.
