RiggingSense

RiggingSense teaches the physics every stage rigger is expected to already know. Drag a load along a two-hoist truss and watch the reactions split — and go unstable when it passes the last point. Drag a bridle apex and watch leg tension climb as the legs flatten. Every result can show its full working, and a trainer scores your estimate before it shows the answer.

Who it is for

• Stagehands and apprentice riggers building intuition before the responsibility.
• Lighting and audio techs who hang things and want to understand what the rigger is telling them.
• Students, trainers and toolbox talks — a visual teaching aid with the maths shown.

What makes it different

• Drag it and see. Reactions, bending moment, bridle tensions — all update live as you move the load or the apex.
• Failure modes, named. Uplift when a load passes the last hoist, skew when one hoist takes far more than the other, each explained in plain words.
• Estimate first, then check. A trainer with levels, tightening tolerances, streaks and badges.
• A 20-term glossary linked inline throughout, also published at /riggingsense/glossary.
