How can i provide gravity on a space station???

Willy Ley, a German engineer during World War 2 created a design for a space station in the shape of a toroid (Wheel) that spun about its center axis. This created an artificial gravity via the centrifugal force. Different gravity levels could be simulated by concentric toriods at varying distances from the center axis of rotation.

Werner Von Braun took up this idea when he was recruited to lead USA's Space Team after the war.

Your space station must have a central axis on which to spin. Changing the speed of the spin will allow you to change how much gravity is present. Gravity will be create as an outward force, pushing away from the axis.

The wheel is the most common design for a space station as it gives a semi smooth walkway (perimeter of the wheel) and a central axis that is the same distance to all points of the perimeter.

Make your space station spin, the centripical force will pull you towards the wall, so build your floor on the walls. This will cause an artificial gravity. Or you could simply buy a gravity machine(too bad they dont exist). I hope this is helpful, and I wish you luck on your....um.... space station, and if you need any more help on anything space related just ask. Im just a click away.

a fast spin with short arms

a ship has already been thought of that can do just that....

only problem is it takes and enormous amount of energy to get the whole ring to spin.... its very heavy even in low G

there is also

magnatism (like magnetic boots)

acceleration ---- you end up being forced to the back of the ship and can stand "up" "sideways"

OR

just put a HUGE amount of mass inside a ship..... the larger the mass, the more gravity you get.

Rotation around an axis.

Impart rotation.

A stern look usually works!

Make it spin

..

Say something serious.
