Bridget v0.1.0
A playful truss editor for students. Draw a bridge, see the forces flow, and export it to the West Point Bridge Designer for a full load test.
Members color-code by tension (blue) and compression (red) using the Direct Stiffness Method. Real-time diagnostics tell you how many members are missing and suggest where to add them.
Designed to help kids visualize how forces move through a truss before they run the official load test in WPBD — where the truck rolls across and you see where it breaks.
Built on the coordinate system and .bdc file format of the West Point Bridge Designer (ASCE).
