Tremors: Kabel

Model Designing Event
PROBLEM STATEMENT

In this event participants have to design and build a cable stayed bridge using popsicle sticks and strings.

  • Round 1: Dimension checking
  • Round 2: Load testing (We will provide a steel plate with hooks to conduct gradual loading.)
  • Each team should be of maximum 4 members.
  • Materials to be used: Popsicle sticks, strings, threads and Fevicol of SH grade.
  • Use of any other adhesive, etc. is prohibited and participants using it will be disqualified from the event.
  • Threads are allowed only for cable.
  • Strings cannot be used to tie popsicle sticks.
  • 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 must be 100 cm.
  • Considering Base plate as foundation level, High flood level is 20 cm, free board is 3 cm and road level is 30 cm.
  • No type of coatings or paint are allowed on the popsicle bridge.

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.
  • Cross and double bracings are not allowed.
  • 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 100cm.
  • The no. of panels in one Girder should not be more than 10.
  • Width of girder must be 10cm (o/o)Height/Depth of the girder must be 10cm (o/o).
  • The deck (road level) should be at the height of 30 cm from the base-plate.
  • Either side suspension should be maximum 20cm.

Specifications for Cable:
  • Participants cannot use nuts/bolts, hinges, groves are not allowed to tie the cables(rope).
  • Nylon thread has to be used with dia. between 1-3 mm.
  • Any other type of rope/thread is not allowed.

Specifications for Column:
  • 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 in same alignment.
  • 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.
  • Single bracing are allowed. No cross bracings and double bracings allowed.
  • The height of the stand columns should be 60 cm.
  • No. of panels must not be more than 6.
  • The size of stand columns should be 11*11(l*b) i/i.
  • Stand columns must be fixed with the base plate (ply wood of 6 mm thickness and 30cm*30cm cross section) for each column separately.
  • For attaching stand columns with base plate- nut/bolt mechanism or clamps can be used.
  • Grooves in the structure are not allowed.
  • Only SH grade Fevicol can be used as Glue.
