Bridge Builder
This interactive simulator explores Bridge Builder in Engineering. Place beams and joints. Apply load. See stress distribution. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Engineering.

How it works
Static **2D truss** with axial bar stiffness **EA**. Supports are detected on the dashed **ground** line: **pin** (leftmost) and **roller** (rightmost). Member colors: warm = **tension**, cool = **blue** compression. Faint overlay = amplified **deformed** geometry.
