Ok, humor me, you mention that, the pin being smaller diameter than the ball diameter shouldn't be an issue. So, each respective diameter shouldn't factor in since they share a common center which will turn at the same rate. One would only need to find the outer rim speed and the pins should be at the same rate, yes?? If that's true all I would need then is a hall sensor and that would give me the rate the ball is spinning about its own axis. But that still doesn't address the pins movement in the track around the equatorial region and the rate it travels around the ring must also be equal to the rim speed of the ball. This is apperantly how Anti-gravity is achieved. My understanding is that when this is achieved the mass of the mechanism is being thrown in all directions away from its center (That's very loosly described), weight stays the same. So relative to mother Earth this mechism has increased in size and inturn it will move away from 'center gravity'. Please note that this last paragraph is speculation on my part. Hence the original post. Okay. Now that we have that under our belt. Till Then Nullflux8 Last edited by nullflux8; Oct 22nd 2012 at 04:57 PM. Reason: grammer

The mechanism you've been describing doesn't quite accomplish that, because the instantaneous rotational acceleration of points on the sphere are not necessarily directed radially away from the center of the sphere. It works for some of the points - for example at the axis points and the points 90 degrees from them - but not for the majority of points. Also the magnitude of the acceleration is not uniform for all points. If uniform acceleration of every point on the surface is your goal I don't think you'll get there with this approach. Perhaps you might want to consider something else - for example if you inflate a spherical balloon so that its diameter expands with constant acceleration every poionty would have uiniform radial acceleration - would that accomplish what you're looking for? Also I'm curious whether you really believe this anti-gravity stuff, or are you just trying to understand how to devise a mechanism? Last edited by ChipB; Oct 29th 2012 at 06:27 AM.

No the surface of the balls weight/mass moves away perpendicular to center. That is how it moves into the other axis (horizontaly around the guide) gyroscopicly. "Also I'm curious whether you really believe this anti-gravity stuff, or are you just trying to understand how to devise a mechanism? " exactly...It's a fun project with all kinds of hurdles. What I'm hoping for is to devise a gyroscopic rotor/motor in hopes to furthering exercise machines and the like.... Just today, I'm gluing a home made magnet switch, we'll see how it does tomorrow.

Mass curves space-time downwards. If an object orbits another object it is following the curve of gravitation so that its inertia and its gravitational attraction make a resultant force causing it to curve in exact proportion to the gravitational curve it is within. If an object is rotating around an object with momentum greater than the inertia for orbital insertion it will escape orbit unless it is held fast by some kind of mechanical device. The resultant force of the momentum and inertia and gravitational attraction creates a force called centrifugal force. Your theoretical object is attempting to create centrifugal force along two axes, however, the actual path that object would take if it were attached to the outside of your device would look like a figure 8. In order to test my claim you could attach a small LED to the outside of your device rotated a full rotation in both axes in the dark and see what pattern it creates. The figure 8 would stay in one hemisphere. The hemisphere it would stay in would be dependent on the direction of the second axis rotation. If the LED started on the top and the wheel was rotating counterclockwise in the second axis of rotation used the right-hand rule the figure 8 would remain in the hemisphere closest to the viewer if the wheel started out in a perpendicular plane to the direction the viewer was looking. In order to get the LED to move into other hemispheres you would have to add an additional axis of rotation creating a full three-dimensional gyroscope. Imagine the device making a quarter turn in each orthogonal axis. The first quarter turn in each orthogonal axis would end up canceling each other out and the LED would remain in the same location at the top of the device . The second quarter turn in each orthogonal axis would cause the LED to change to the bottom end of the vertical axis of the device along an S-shaped curve on the far side of the device. The third quarter turn would result in the LED to remain at the bottom end of the vertical axis as all rotations would cancel out. The fourth quarter turn would result in an additional S-shaped curve on the near side where the LED would go to the top end of the vertical axis of the device. The paths taken of the LED in these two examples would not have consistent centrifugal force to cancel out gravitational force and would have to be mechanically imposed, which is why satellites do not orbit this way. If you are looking to cancel out gravitational force in approximately every orthogonal axis with centrifugal force a possible mechanical device for this would be composed of spherical shells fitted inside one another like Russian dolls. In order to approximate every direction gravity is acting upon there would need to be three sets of 360 million shells. Each shell would rotate in one axis and the shell in the next layer would rotate on another axis which was one millionth of a degree different, therefore, the first set of 360 million shells would encompass 360 degrees along the first orthogonal plane. Each shell would have an independent axis of rotation which would not be influenced by friction, theoretically. The second set of 360 million shells would encompass 360 degrees along the second orthogonal plane and the third set of 360 million shells would encompass 360 degrees along the third orthogonal plane. If these shells were extremely thin so that they did not create a very wide boundary between them and the shells were of different densities to allow the resultant centrifugal force of the shells to exactly match the gravitational force the whole object exerted this object would have a approximate balance between centrifugal force and gravitational force as a whole, thus, this object would exhibit theoretical antigravity yet since centrifugal force does not curves space-time this antigravity object would still have the same curvature of space-time and objects orbiting it would not notice anything different.

This might be possible with fields however, but then you would have no mass, so what would be the use? This does touch a point where I am rather stuck in my own theories. __________________ Deception is a complex concept which the human mind is unable to resolve...
