Directional Control of Weight Forces in Rotating Bodies
The frame-dragging effect tells us that when a body rotates around itself the metric of spacetime around its surface is dragged. This occurs, for example, in the metric of the spacetime around the Earth surface, and produces the well-known phenomenon of shifting of the orbits of the satellites near the Earth. Such as the orbits of the satellites, the force lines of the gravitational field produced by rotating bodies are also affected by the frame-dragging effect. This means that the direction of a gravitational central force in a rotating body should be radially displaced, in respect to their initial position. In this work, we show that the radial displacement angle depends on the angular velocity of the rotating body, and that this fact point to the possibility of controlling the direction of these gravitational central forces, simply by controlling the angular velocity of the rotating body.
