Opportunity brief
Overview
Design Light. Build Strong. Hold the Load.
Edge of Collapse is the bridge model engineering competition of Addovedi 2026 (NIT Arunachal Pradesh). Teams build a lightweight three-hinged bridge that must carry the maximum load. The winner has the highest load-to-self-weight ratio. Held on campus, 28-30 October 2026.
Guidelines
- Eligibility: college students; valid student ID required.
- Team size: 3 to 4 members. One bridge per team.
- Inter-college / inter-specialization: allowed. Open to all branches.
- Materials: popsicle sticks and water-based white glue (PVA) only. No metal, plastic, cardboard, bamboo or pre-made parts.
- Size: 50 cm long, 45 cm clear span, deck at least 5 cm wide, three-hinged, no anchoring.
- Rounds: Design and Inspection, Knowledge of the Bridge, Load Test.
- Registration: sign up on the Addovedi website, register for Edge of Collapse to get your Team ID, then register on Unstop with the Team ID + the leader's Addovedi ID.
- Registration fee: Rs. 50 per member (Rs. 150 for 3, Rs. 200 for 4).
- Prize pool: Rs. 8,000 cash (total worth Rs. 17,000 including hoodies).
Rules
- Build in advance and bring the finished bridge. No changes after weighing and submission. Glue must be fully cured.
- Prohibited materials or exceeding size or weight limits = immediate disqualification and no prizes.
- 5 minutes per team at the testing station. Stay behind the safety line.
- Ranking: efficiency ratio (max load / self-weight). Tie: lighter bridge, then lower deflection.
- Do not damage other teams' models or equipment. Misconduct = disqualification.
- Judges' and organisers' decisions are final. Rules may be modified and will be communicated.
