Span

Build a bridge from concrete, steel and wire, then watch it hold or collapse.

Span during a test: a steel deck and concrete supports across a river, with the red load masses swelling

#include "/Apps/Span/Run"; Drag between points to build. c, s and w pick the material, and Space runs the test. The cheapest bridge that stays up wins.

Each member is a spring with its own stiffness and strength, and each member snaps when overloaded. The red loads swell and shrink on a sine wave, so the peak load travels along the deck.
