Topic: Structures · Ages: 12-14
Truss simulator online for students: build a structure from bars and joints, add supports and loads and find out whether it holds or collapses. Each bar is colored by the force it carries, red for tension and blue for compression, with the reactions at the supports. A triangulation mode shows why a square collapses and a triangle does not, and a challenge asks you to carry a load to the supports.
