While the force of gravity is directed towards the center of mass, the centrifugal force, on the other hand, is directed away from the center. Taking its smallness into account, the radial orientation of the vertical direction, which in most cases is irrelevant on the Earth due to its size, now clearly becomes evident in the space station. Rotating air lock, movement in the axial direction. However, all of these phenomena make themselves felt that much less, the larger the diameter of the wheel. This segment has a cylindrical shape.
People can, therefore, move easily out of the habitat wheel into the air lock.
Then, the latter begins to rotate by electrical power opposite to the direction of rotation of the habitat wheel until it reaches the same rotational speed as the habitat wheel. As a result, the air lock is stationary in relation to outer space and can now be departed just as if the habitat wheel were not even rotating. Even the cable connection at the other side of the axle segment is designed in a basically similar manner in order to prevent the cable from becoming twisted by the rotation of the habitat wheel. As a result, the shaft is continually stationary in relation to outer space. The cable extending from the shaft cannot, in fact, be affected by the rotation of the habitat wheel.
