1. Materials will be provided for the competition i.e. Sticks, glue, thread, tools (scissors, Cutters, clamps/clothes’ clips). 2. Participants may bring any other tools they wish to use and will be allowed to use them subject to the approval of the event heads. 3. Participants must build the bridge during the competition and not at home. 4. There are 2 rounds: The truss bridge round: Round 1 (Day 1) The suspension bridge round: Round 2 (Day 2) Note: This round may be extended to the 3rd day . Read details in duration of round 2. |
| Round 1 |
Problem Statement: Contestants are expected to make a beam bridge with trusses on both sides. The bridge should be simply supported (i.e. should have two supports one at each end). Note : The supports will be provided by the organizers. The supporting columns will be of 4*4cm. MATERIALS FOR BRIDGE: Popsicle Sticks Glue Length: Effective span (distance between supports) = 40cm Min length of the bridge = 46cm Total width of bridge<= length of 1 Popsicle stick Roadway (width of deck available for loading) => 9cm 1) Make a sketch of the bridge you are going to make in two views (plan and elevation). Make two such drawings and submit one to the organizers and keep one for yourself. 20 minutes will be provided for this purpose. 2) A fixed amount of fake money will be provided to buy the Popsicle sticks and the fevicol. Each team may send only one representative to the counter. 3) The contestants may then start building the bridge. Building Time: 3.5 hrs Drying time: 45 mins 1) Management of funds and materials: cost and materials are an important aspect of bridge designing. Bonus points will be rewarded to those who manage to optimize their material requirements. 2) Load bearing: The bridge will be tested by gradually loading it till failure. Failure is the defined as the breaking or cracking of any part of the bridge. RATIO OF LOAD APPLIED TO WEIGHT OF THE BRIDGE WILL BE CALCULATED. The weight that the bridge sustains just before failure will be considered as the maximum load. 1. Dimensional accuracy is important. Bridges not satisfying the required dimensions will be disqualified. 2. Notches may be made. 3. Lamination of the Popsicle sticks is permitted. 4. Popsicle sticks can be soaked in water. |
| Round 2 |
Based on Round 1, 10 teams will be chosen for round 2. DURATION: Building Time: 4 hrs (Extra building time of 2 hrs. will be provided to those who need it on day three however those who complete on time stand to gain since their efficiencies will be multiplied by 1.2) Drying Time: 1 hr Popsicle sticks Glue String (for cables and suspenders) Length: Distance between the two towers = 60 cm Width: not more than the length of a popsicle stick Roadway: Not less that 9 cm Clearance: The distance between the lowest point of the deck and the end of the tower should be 15 cm Contestants are not expected to build the deck trusses of the suspension bridge. 1. The deck must be directly supported by the cables. 2. There is no restriction on the amount of string however it will contribute the weight of the bridge. 3. The main cable connecting the 2 towers must not touch the bridge at any point. 4. There is no restriction on height of the towers. 5. There must be only 2 towers. 6. Anchorages will be provided for the cables.
Efficiency is the only judging criteria Efficiency Ratio: Max wt sustained/ Wt of bridge Wt. of bridge: (Length of string*2) +Wt. of the bridge |
