The Rules

Your model should be strong enough to carry a vertical load. ( Why?)

  1. Every floor of your model must be able to carry 10 grams for each square centimetre of its area.

  2. Your model must be able to carry the required load on all floors at the same time.

  3. You must test your model to make sure it can carry the total load, before you enter the preliminary round of the competition.

Applying the Load

For the competition on the shaking-table the models will be loaded in the following way:

  • We will add the vertical load to models using steel blocks.

  • If the ground floor of your model is directly on the MDF base board, we will not put any mass on the ground floor, because it does not affect the model when it is being shaken.

  • Each steel block will be 6.0 x 4.5 x 3.0 cm with a mass of 635 grams ( Why ? )

  • The number of blocks placed on each floor will be the lowest number needed to cover the minimum required mass for that floor.
    ( Work it Out )
  • You must provide fixings on your model to show where the blocks will go. Do not add the fixings until after you have done the Vertical Load Test.
