Rules for Vertical
Load
Your model should be strong enough
to carry a vertical
load.
( Why?)
 Every floor of your model must be able to carry
10 grams for each square centimetre of its area.
 Your model must be able to carry the required load
on all floors at the same time.
 On the day of the challenge, you can use the weights
provided to check that your model can carry the vertical
load.
Applying the Load
When your model is tested on the ShakingTable
it will be loaded in the following way:
 We will add the vertical load to models using steel
blocks., which we will glue firmly in place.
 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 )
Fixings for Steel
Blocks
 You must provide fixings on your model to show where
the blocks will go.
 Make the space for the blocks slightly larger than
required (by about 2mm) to make sure they fit well.
 Make sure that your floor can support the steel
blocks. ( Show
