Good catch. Somewhere along the line I moved the decimal from sandstone's 2,300 kg to the aberrant 2.3 kg. This drastically damages my perception, but better now than later.
I'm struggling with your insightful (and gracious) analysis, but while trying to make my numbers coordinate with yours, I realized I gave you misleading data. The "pipe" object is indeed 110m thick, but I neglected to mention that 80% of its original mass (at 2.3kg/m^3 density) has been hollowed...
OUCH!
Actually, I calculated my thickness as 110 meters, an essential dimension, but I'm sure your calculations are correct, so I'll need to modify something. Quoting myself, this is another "essential:"
However, my underlying intention is to show how we can take our next steps into space at a...
Imagine a 400-meter-long pipe with a 1600-meter diameter, floating in inter-planetary space. It is spinning at 0.5 gravity along its major axis and there are no secondary-axes spins. We need to increase rotation to 0.85 g. Its density is a uniform 2.3 kg/m³ and it weighs 49,120,056 kg.
Thanks to...
