Tremors Viaduct

Engineering problems are under-defined, there are many solutions, good, bad and indifferent. The art is to arrive at a good solution. This is a creative activity, involving imagination, intuition and deliberate choice.

Problem Statement

In this event Participants have to design and build a Bascule bridge (double leaf) using Popsicle sticks which should be able to pass the given object and carry a given load.

Each team should be of maximum 4 members.
Materials to be used: Popsicle sticks, syringes and Fevicol of SH grade.
Use of any other adhesive, etc. is prohibited and participants using it will be disqualified from the event.
All the members of the structure must be such that the moment of inertia must be minimum in the direction of loading.
All the models must be taken for the self-weighing during the specified period of time (any entry after that won’t be accepted and would be disqualified).
No changes in the model after the self-weighing would be allowed and any team doing so without the permission of the core committee member would be disqualified.
The decision of the judges and core committee will be final regarding any discrepancy on the spot or before the event.

OUT TO OUT LENGTH OF THE BRIDGE MUST BE 100 cm
Considering Base plate as foundation level, High flood level is 15 cm, free board is 3 cm and road level is 30 cm.

Popsicle Stick:

Maximum length 115 mm, width 13 mm and thickness 3 mm.
The Popsicle sticks can be cut or trimmed to any shape or size.
SH grade Fevicol must be used only to build the structure.
Girder specifications:
Thickness of any member should not exceed 3 Popsicle stick.
Single Bracings are allowed in the girder of the bridge.
There should not be any bracing as viewed in the plan.
Grooves in the structure are not allowed.
All the members of the structure must be such that the moment of inertia must be minimum in the direction of loading.
Only SH grade Fevicol can be used as Glue.
Total Length of one girder should not exceed 50 cm.
The no. of panels in one Girder should not be more than 5. (total 10 in two girder)
Width of girder must be 8 cm (i/i)
Height/Depth of the girder must be 12 cm (o/o)
Use of ball bearing is not allowed.
The deck (road level) should be at the height of 30 cm from the base-plate.
Angle of opening must be more than 45 degree.

Specifications for Hinge Mechanism:

Participants can use any type of hinge mechanism.
Grooves are allowed to equip the hinge mechanism.

Specifications for Columns:

The design of Columns has to be open-web.
Thickness of any member should not exceed 3 Popsicle sticks.
All the Panels of vertical member must have same alignment.
Cross Bracings are allowed up to 30 cm.
All the members of the structure must be such that the moment of inertia must be minimum in the direction of loading.
There should not be any bracing as viewed in the plan.
The height of the stand columns should be 50 cm.
No. of panels must not be more than 5
The size of stand columns should be 12*12 (l*b) o/o
Stand columns must be fixed with the base plate (ply wood of 6 mm thickness and 30cm*30cm cross section) for each leaves separately.
For attaching stand columns with base plate- nut/bolt mechanism or clamps can be used.
Grooves in the structure are not allowed.
Use of ball bearing is not allowed.
Only SH grade Fevicol can be used as Glue.

Specifications For Hydraulic Mechanism :

Maximum 4 Syringes can be used for hydraulic mechanism.
Participants must attach the hydraulic mechanism with the column.
Only two member can operate the hydraulic mechanism.
Minimum distance between Syringe and base of column is 5 cm.

Round 1:

Dimension and Hydraulic Mechanism of Model will be checked.

Round 2:

Vessel of X height will be passed under the bridge after lifting of the girders.

Round 3:

Point load/udl will be applied on the bridge deck chosen by Core Committee. The point load/udl will be equal to 1.5 times the self-weight of the bridge along with the base plate.
Point load will be increased up to the failure of the model.

The judging sheet will be based on the formula given below.
