It was more that Cory then described the process as “brick basically melted” which was not what the presenter had said or what happened.

Nice work by the way.

]]>My brief in this case was to answer a simple question about the crush strength of a Lego brick. If you listen to the BBC podcast, or read the original BBC article, you will see that I clearly made the point that structural failure through buckling would occur first, and this was backed up by a professional Lego builder who was also interviewed.

Incidentally, buckling of a Lego column is significantly more complicated than simple elastic / Euler buckling, because of the possibility of bricks pulling apart under tension. It’s more like buckling of concrete columns, which crack under relatively low tensile stress but can take very high compressive ones.

]]>Clearly this was left out of the calculations.

]]>Three times as much? 10,777 m… Now we’re talking! ]]>

I suppose that it might be quite a bit taller, considering how the weight spreads and all… I’m sure any architect with a geeky bent (or a mathematician) can easily provide us with an answer to this burning question.

(all the necessary data is in the article; 2×2 bricks stacked in the obvious pyramid pattern..) ]]>
