    all right you have a high speed ferris wheel feeded with a nuclear central

    you put a tube 1 km long, the cannon, diametrally in the ferris wheel

    you put a ship in the center of the tube, the center of the wheel

    you start rotating the ferris wheel and so you do with the cocpit in such a way they have oposite sense so on this way the astronaut doesnt actually rotate since both rotations nullify and he doesnt get sea sick

    you rotate the cannon faster and faster, as much as the nuclear central can

    being the ship in the axe of rotation it wont move

    when the rotation is maximum you push the ship slightly so it goes slightly off center

    voila the ship acquires 10000 g acceleration the astronaut feels 0 g

    edit:

    either of two:

    im a genius or the world is staged and im truman

    do you think me a genious?

    You may be right Raaaid, the astronaut might well not feel the 10000g acceleration, because it will kill him before his nervous system has time to tell him about it. Not that a spacecraft capable of holding together under those sort of forces sounds very likely anyway.

    You can't outsmart the laws of physics by trying to make them dizzy...

    put a spring in a tube and swing the tube, with your mind

    will the spring compress?

    then it feels 0 g

    apply negative g to the plane and let a pencil in the air

    the pencil goes up accelerating as much as negative g is applied

    how much g does the pencil feel?

    exacaltly 0 g just as free fall

    you are 10 m away from the center of a rotating tube fixed in the tube feeling 10 g cause of the centrifugal force

    you unfix so you can move along the tube, how many g do you feel now as you "fall along the tube"

    yes 0 g

    What makes you think the spring 'feels' 0 G? If there was no force on it, why would it compress?

    Your reasoning is wrong Raaaid. The astronaut feels just as much g as the ship does. Example with pen floating in a plane is different because the experiment is done in gravitational field, this one isn't.

    And secondly, it's not a linear motion, it's more complicated since the walls of the tube also push the ship in other directions. If you look at the experiment from above, you can see that ship travels along some kind of spiral, not a straight line.

    I'd suggest going through a course of analitical mechanics and attempt a problem or two there - many of them involve "rotating tubes with springs and/or balls in them", but I know you probably won't anyway.

    of course i could be wrong

    im not analizing lateral g but g along the tube

    if you put a spring on the ground gravity compresses it

    if you put a spring on a frictionless tube and swing it as to throw away the spring is just imposible it compreses(it cant feel any g along the tube) for the mere fact its not posible for it to hold onto nothing along the tube, is just holded laterally

    the ship and the astronaut along the tube are falling along the tube at 10000 g at free fall, and you know in free fall you feel 0 g, of course the astronaut feels the same gravity than the ship but both feel 0 g along the tube since both are at free fall of an artifical gravity

    wtf has this got to do with WWII aviation.

    cant you keep this kind of 'insight' of yours to off topic...

    oh come on i post it here cause i think people here as me like aeronautics

    if i asked here how many kg of thrust have the space shuttle it would be all right but if i propose an idea for an space shutle is not

    we all like aviation come on what if im right

    I think the point was this thread should have been posted in the "off Topic" forum.

    Even the thrust of the space shuttle is not really relevant to general discussion.

    You can't accelerate a person without accelerating them and that means G-force, period.
    Same thing with the spring or any other mass object.
