Gravity and centrifugal forces.
Gravity is the most common force acting at the large scale in the universe. With centrifugal forces it provides the universal set of relationships, and those forces together also makes our reality as we know and provide our standard predictions according to environment we living in. Force of gravity is important especially in planetary conditions for humans. However in a case, we want to overcome it or escape out of it, the problem begins to be crucial. Usually we want to give the payloads in rockets the escape velocity, needed to send it to the orbit. In Earth's conditions this is about 11,2 km/s. What stays the main problem, we don't have any solid way of reusable transport in outer space besides transport to orbit and nearest planets and moons. Harnessing a proper technology to overcome universal gravitation won't be easy. However just the centrifugal force seems to be a proper way to switch off the gravitation. The centrifugal force indicates some bipolar gravitation properties as is shown on the Pic.1 drawing, what is rather relying on position of observer with the same rotation as the ring (assume that this ring is very big one perhaps up to kilometer in diameter so the drawing is not in scale). If those cases were took places in external gravity field from massive object like a planet field, than the situation is getting complicated. The observer in the first case will be affected with decreasing resulting force of gravity every time the upper side of the ring with him reaches top (assume he has strong magnetic shoes and suite and the ring is made from steel) and if he was upside down than the force of gravity could to cause him to take off from this ring. In the second case the observer is safely protected from fall on condition that the ring is rotating enough quickly, but there will be the difference in perceptible gravity force. The force will be weaker on the top and greater on the bottom of such a oriented ring, the Pic. 2 drawing is showing just the situation in planet's conditions.
On the Pic.4 drawing there is shown a system that is able to change rotation of rotor centrifugal force to linear force aimed in up direction. This rotor has different resulting radius dimension increased additionally by the mass hole partial length. In the bottom position the rotor's bottom half is entirely hidden into hole. The problem of friction is valid but this is simple system and now is only for this educational aims. This system has its counterweight and here the only difference in forces acting in the device comes from radius of rotation - the different radius dimension. Weight of masses still stays the same and also rotation speed is constant.

Why to show this obvious properties? I think the only important and pragmatic for any use reaction is in situation of gravity planet's conditions and the situation under number "2" when he is turned upside down. In this situation the mass of the observer (or any other material object) is pushing on the ring with the force proportional to speed of rotation, own mass and another factor which is radius of rotation. On a Pic.3 drawing there is shown as a red arrows the pressure being laid on internal, upper side of the rotating ring. This is because the mechanical forces are not balanced any longer.

Unbalanced centrifugal force is caused by mass without counterweight. This is the point, because no operating like this could happen without counterweight in every example I've shown here - because in outer space the ring will be torn apart in every direction.
