Thanks man :) also that's so fucking huge
What diameter would a rotating space ring need to have 1G and a 24 hour rotation period?
Grayson Lopez
Jackson Peterson
[eqn]F=m\cdot g\\F={{m\cdot v^2}\over{r}}\\v={{2\cdot r\cdot \pi} \over {T}}\\m\cdot g={{m\cdot 2^2\cdot r^2\cdot \pi^2}\over{r\cdot T^2}}\\g={{4\cdot r\cdot \pi^2}\over{T^2}}\\r={{g\cdot T^2}\over{4\cdot \pi^2}}[/eqn]
Now insert your values
Jace Robinson
the second line was supposed to read
angular velocity*
Hudson Gray
2,305,287 miles in diametre.
What... the... fuck.
O'Neill's 5 miles is much more realistic.

I'm pretty sure that's high school physics or even lower.
Bentley Thompson
8th grade I would assume.
Xavier Jones
I TA for freshman physics at a University of California campus. You would be surprised.
But you're right. I learned it in 11th grade. It's still technically freshman physics though.
Grayson Green
Why would you want it to rotate once every 24 hours? You don't want any windows in there, most realistic designs have an inner steel cylinder that's sealed off and enclosed in an outer non-rotating shell made out of residual materials left over after you've smelted the asteroid. Windows are a huge structural weakness and your main concern in there is getting rid of heat, so you want as little sunlight as possible.
Carson Ward
There's one thing I could never understand about angular velocity. Why does it equal to 2 pi / T? I dont get the 2 pi part. Angular velocity means angle in time. 2 pi is not an angle but a number. So why do we write it as 2 pi at the top?
