How does gravity work in structures such as these?

If you spin a giant cylinder in space that will simulate gravity. Dint you see 2001 A Space Odyssey?

Space Station?

"A rotating spacecraft will produce the feeling of gravity on its inside hull. The rotation drives any object inside the spacecraft toward the hull, thereby giving the appearance of a gravitational pull directed outward. Often referred to as a centrifugal force, the "pull" is actually a manifestation of the objects inside the spacecraft attempting to travel in a straight line due to inertia. The spacecraft's hull provides the centripetal force required for the objects to travel in a circle (if they continued in a straight line, they would leave the spacecraft's confines). Thus, the gravity felt by the objects is simply the reaction force of the object on the hull reacting to the centripetal force of the hull on the object, in accordance with Newton's Third Law."

if you want to test this out for yourself, get a bucket with a handle, fill it up with water, and spin it around in a circular motion either horizontally or vertically, once the bucket is swining fast enough, the water will be held in place.

Orbital Space Colonies are cool and all.

But won't it suck when the colonies furthest from earth declare themselves independent of earth and start a war against the earth (which is now united into a huge federation).

A war in which the spacenoids decide to drop an old colony on earth destroying most of Australia.

I just don't think it's worth it.

what are you talking about, Australia will be destroyed, of course it shall be worth it.

Centrifugal force, yeah. Which is where the first pic’s artist fucked up. (S)He’s drawn the floor curved in two directions when it should be flat parallel to the axis of rotation.

The reason for that is probably structural, having a flat 'floor' would require vastly stronger materials in both along the center of the living space and at the edges.

Designing it 'curved' minimizes stress accumilation along these points.

How do you explain the water then?

Think about it for a second before you answer. There is no way in hell the water would be calm.

Let alone the fact the spinning station would need to have put the water in FIRST before anything else because it would create massive waves until it started to flow in other direction to which the station is rotating.

What would happen after that is you'd have the water flowing at the same speed as the station is spinning. So forget about going out in a boat or for a swim, you'll get tore up by the current.

To hold a liquid you need a lot more force then a person, because it's LIQUID, not a solid object. So the spinning would have to be very fast. This would make it seem like very heavy gravity to a human.

One g ought to do the trick - it does here.

your whole argument seems invalid. Why would the water need to be put in first? its not like a giant space station would start spinning to its final speed immediately anyway.

and why not a boat, once the station and water are moving at the same speed, the water would be stationary, it wouldnt have currents, as currents are caused by water moving downwards off of mountains, or temperature variations. Since there would be no mountains or any real temperature variations, why would the water move at all?

like as was said, if you add more water into the spinning bucket, it doesnt cause huge tidal waves, or huge current changes, the "gravity" would act the same as here

and if i can walk properly in the space station, then im sure the water would stay there fine as well

Small problem is.. the water wouldn't be moving in the same rotation of the station. If the station was spinning clockwise, the water would be flowing counter clockwise. At least from a perspective of the station as a whole.

If you want to test this out, get glass of water, wait for it to "settle" then turn the glass. The water sits stationary because it can. It's not until you stop spinning the glass that the water starts turning in the same rotation as what you where spinning the glass.

I'm talking about direct spinning too, not "swishing" the glass around in circles to get it moving. Just put the glass on the table, and rotate it clockwise or counter clockwise.

Since the water doesn't turn with the glass. If you where small enough and standing on the inside of the glass like these people are, The water would look as if it's moving. And it would be moving with one hell of a current.

It's all about fluid dynamics.

Once the space station builds up momentum and gets to it's final speed, it's just a matter of time before the liquid starts rotating with it because of friction.

I'm sorry, dude. Doesn't work that way at ALL. Not on that scale and not in zero gravity.
