Lego Technic Strength

Before I release this report to the wider Lego community, I want to get some feedback from a much smaller audience.

Please read and comment on anything what so ever. Any feedback is good.

I'm not a lego expert but it was very clear to me, especially with the pictures.

There are a couple of places where there is *** rather than the expected number in the charts and tables at the end. If this is intended, you might want to put --- or N/A instead of ***, which usually means that a number is too wide for its field.

In the pictures on p9, the point of failure is right at the end of the crushed area. Is it possible that the beam failed there because it was crushed, and that an undamaged beam would be stronger or fail in a different way?

Fixed, It was the output from the machine that was never received.

To the second comment, It is possible that an "undamaged" beam would not be crushed. I have no doubt that the beam failed there because there was a build up from stresses because it was crushed. My point is that even if the beam was undamaged, it would fail in the same way and location as there was a concentration of forces where the main span and connections meet.
