...No, it applies to any physical object It applies *less* to a hollow object than a solid one but it still applies, it determines how thick the structural part of the machine needs to be to support its weight The whole point here is you can't make it arbitrarily thin

There is no "less applying". The scaling between a hollow object and a solid one is entirely different. Structural elements will need to grow but not nearly at a square/cube rate. The hull, if you keep the same thickness, would scale at the square, not the cube.

You need strong support beams to handle that too, yes, but those won't increase at a cubed rate either. If hollow structures were anywhere remotely at a cubed scaling, we wouldn't be able to build a building larger than a house. And we're not building mechs out of heavy concrete.

Objects that scale in even one dimension still have extra mass that needs to be supported. If you have a girder that you're trying to make longer, then the extra weight of one end will snap/crush the other end even if it's hollow at *some* point

Yeah the point is there's a maximum size you can make a skyscraper no matter what you make it out of because every building material will snap and fall over at a certain point, no matter how thin you make the girders

There is? I didn't know there was a cap on stationary building size

You could get around that by building out around the base, right?

The Eiffel Tower when it was designed was specifically designed to be the tallest building possible using the materials available in those quantities then (wrought iron) and everything about its shape is determined by structural engineering factors, which is why many hated it

But yeah that's the kind of design you use to max out the strength of your building material, a big hollow base supporting a tapering structure The supertall skyscrapers today are about as high as you can get without a visible base like that

Right, but in the specific case of skyscrapers, can't we build a big low rise complex with a huge basement, with a high rise, slightly narrower, on top, and then a skyscraper on top of that and the a narrower skyscraper on top of that?

The issue is that for proposed supertall structures like the Tokyo X-Seed 4000 the base would be so large that it likely wouldn't be cost effective to try to build out habitable floors in it rather than leaving it completely hollow

...Why not?

Because for a massive project like that every added newton of stress on the structure is very expensive and the base has to be very wide so building a floor that's attached to it in a way that distributes weight evenly is hard
