Statics Tutor
Edit a statics problem as JSON and watch the reactions, member forces, and shear–moment diagrams — with worked step-by-step solutions — recompute live in your browser. Under the hood: a JSON model, a pure-JS solver, and a reactive SVG viewer — no build step, no server.

Guided Walkthrough new
Pick from 5 truss and 6 beam problems and click through the engine-generated worked solution, with per-step canvas highlighting and narration.
Truss Analysis Problem Set
Six problems: method of joints and method of sections, zero-force detection, live-editable diagrams.
Shear & Moment — Problem Set
Six curated beam problems with authored worked steps: point, distributed, and couple loads, with piecewise V(x)/M(x) and hover scrubbing.
Shear & Moment — Live Editor
The same six beams, but the worked steps regenerate as you edit: change a load or support and the full solution rebuilds live.
Mixed Review
MCQs, joints, sections, and shear–moment in one set, each with a full worked solution.
3D Space Trusses (experimental)
Determinate space-truss solver with an orbitable 3D viewer.
