The "cables" aren't really doing much here, by the look of things, since the central tower is ultimately just resting on the truss span; it looks like the main reason the final bridge passed the test was that the anchoring for the tower helped reinforce the center portion of the bottom to take the tensile strain better. From the first box-girder bridge onwards, the failing components were always the pins between the main beams on the bottom (the side bearing much more compressive stress); I'd expect that overlapping the beams more and using axles instead of pins would've improved performance.

Yes, l thought that too. Last one realy must be turned upside down, so it will become upside down suspension bridge. Or he just could prolong main tower to the ground)

Those frames were connected in straight lines, the construction would have been stronger if the frames were connected in an overlapping pattern, like how brick houses are made.

That last bridge makes no sense at all. It sould be supported at the center, not at the ends. The pylon and cables make no difference.

I agree. I'm nowhere near to a physics student, but all these bridges seemed to be built the same way, just with more and more added frames in straight lines. I don't think he understands how physics work and how force is distributed through design.

Great video, fun to watch. If anyone can correct me, please do. I love to learn: I think your bridge design could be improved. Your last bridge, the cable stayed one, has a design flaw; that being that a traditional cable stayed bridge has pillars that are supposed to be load bearing. Instead of the center holding up the edges, you have the edges holding up the center, which favors a truss bridge or a through bridge. Having all that lego in the middle is really heavy, as well. But I'm not an engineer, and I loved watching your video. Just a suggestion.

A suspension bridge is the best idea in my opinion, back in middle school I had an engineering class as an elective, and there was this challenge to make the strongest bridge with just popsicle sticks and anything we brought that our teacher approved of, and I asked if I could bring some light rope, and he agreed, so me and my two friends made a suspension bridge, and we made some cross bearings for the (I forget the technical term) tower thing in the middle, and we won.

The only problem is that in this case. If the beams where ropes they would not do anything. Because the tower is the middle the ropes would experience compression force and as you know. Ropes are too good at compression forces

The "cables" can handle way more during tensile stress than during compressive stress. So the bridge would be stronger if you flipped it upside down.

I believe that one way to reduce stress on the center point of the bridge would be braces that would have rested against the table edges. That way when more weight was added, these braces are more likely to take most of the load rather than the main span of the bridge itself.

You did NOT understand the priciples of suspension bridges. Kables have to be under pull not push. The pillars do not support the part, where they standing but the free hanging parts of the road, where the other ends of the cables are attached. If you want to support the middle of a bridge, you need to bould the pillars at the ends of the bridge and route the kables to the middle. Or simple build an arch bridge.

6:42 you call THAT a pass? Technically it did hold 100kg but it was already beyond damaged and probably would have crashed within a few minutes. If you say that a bridge can carry up to 2t for example, you are saying that the bridge can transport up to 2t without risking damage. That might be a tall task for mere Lego constructions so it's fine if it's risking damage but it shouldn't show obvious signs of material failure I would say.
