I may have asked this before, but I have A Project in mind. This
is much simpler than the last time, when I wanted to build 4
humanoid
robots to pick up a shipping container at the corners and move it.
"Hup, hup, hup, ... detail halt!"

What I want to do this time is to just "slide an I-beam under the
outbuilding, attach a wheeled unit to each end, pivot the building
and
roll it to when I want it." No doubt "A simple procedure involving
lasers." I'm sure. Somewhere.

But, my question is: load capacity of the units. Assume a GW of 3
tons, does that meant that each wheeled unit has to be able to
'carry'
a three ton load, or can I divide the gross weight by 4, add a
"fudge
factor" and hope for the best?

This is one of those things I'd talk to one of the old guys, but I
find I am one of the old guys.

You need to be clearer about the "wheeled unit".

Your one I-beam and four wheels only makes sense to me if you rig it
like a tandem axle trailer. If the two(?) wheels on a side are on a
pivoting bar that lets them adjust to uneven ground then they share
the load, if their axles are rigidly attached to the I-beam then they
don't.


Can you guys not answer the question I didn't ask? Grumble,
grumble; kids these days. Just like when I was a boy.
Reevaluating, I'm going to be working with nanobots which will
interlace sort of like legos or ants. So what I want to know, if each
nanobot can lift a gram, do I need the swarm at one corner to be able
to hoist 3,000,000 grams, or can they just lift a quarter of that? I
don't want to have to turn out more than I need is why I'm asking.
