Your model should be strong enough to
carry a vertical
- 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.
- 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.

for the steel blocks )
