PROBLEM STATEMENT

In this event participants have to design and build a Vertical Lift bridge using Popsicle sticks which can lift upto maximum height and carry a given load.

Register
  • Each team should be of maximum 4 members.
  • Materials to be used: Popsicle sticks, pulleys 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 pulley system
  • 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.

    Round 1:
  • Dimension and pulley system of Model will be checked.
  • Round 2:
  • In this round, assembly of model lift bridge will have to lift the given weight (Round off value of X times of self-weight of model)
  • Round 3:
  • In this round, Girder would be fixed with locking plate at maximum possible height and will be loaded till Failure.
  • (Note: Locking plate will be provided by us)
