        Train Truss Animation

        A truss is an open and airy structure made exceptionally strong by its clever design. This animated sequence from Building Big: Bridges provides a close-up look at how a truss-stiffened bridge manages tension and compression when a train passes over it.

        This resource was adapted from Building Big: Bridges.
