Producing Earths Gravity With Centrifigal Force

[badrush]

Im making a simulator of a 2d(its just a simulation) hallow circle that spins to create gravity to its outer radius. In the circle peaple will live and it will be a new chain of evulotion in there. And i was wondering, becouse i whant to have it as real as posibal. i want it to have the same centrifigal force as the earth(gs). Wich i think is 1g am i right?

I know how big i want the circle becouse it should be right size scaled to humans. But the problem is how fast it should spin.
I have found some calculators to do this but when i for example i use this: CalcTool: Centrifugal force calculator
i get these results
radius:159.154943 km
Linear speed:500km/h (wondering, is this the speed the motor produces or is it the speed of the edge of the circle)

When i calculated this as a test (since i dont know what speed to use yet) i got the variable
Centrifugal acceleration: 0.0123593gs

the g value seems a bit low since i know atleast 9gs have been pruduced in reality.
what is it i got wrong??

Wait, what?

You are physically making a simulator?

Or computer simulator?

[badrush]

computer simulated, sort of a game you can say.

im a programer so

[nothinglol]

Thank god lol.

Anyway yes, Earth creates 1g, because 1g is the force of gravity 1 times, pretty simple.

EDIT: Refer to question below.

What is the radius of your 'earth-circle-thing'?

[badrush]

quote: radius:159.154943 km

[nothinglol]

Oh ok, didn't know if that was the right one you wanted.

[badrush]

yeah i can se that,
anyway
another question:
is Centrifugal acceleration the fing im after since i dont whant the "gravity" to accelerate i whant it to stay at the same vallue.

[nothinglol]

Well, what I find is:

Radius: 1591549.43 meters
Linear Speed: 8838 miles per hour
Angular speed: 0
Mass: 0

Centrifugal acceleration: 1.00014 Gs
Centrifugal force: 0 (due to a lack of mass)
So what you need to figure out is mass imo.

[badrush]

but the mass, isnt that if you whant to se what an object with a special mass weights in the circle??

And another question do you count in earths gravity in your calculation. cus it is a circle in space

the mass is how much 'stuff' there is in the circle. if there is nothing, then there can be no force because nothing spinning no matter how fast still causes nothing. lol (that's my name hehehe)

And you are asking if I accounted for the circle being affected by gravity from earth? No I didn't. I assumed it's in a vacuum. (i.e. space)

[badrush]

its no planet its a holoww planet

heres a easy simply ugly drawn picture for you to understand what i meen :

[nothinglol]

You have to have some mass though. Otherwise you can't generate force because nothing can not generate anything.

Understand?
