From a mechanical engineering viewpoint you can calculate all the forces within a flywheel and determine how fast it can spin based upon the bonding forces. Thus each grinding wheel has different speed ratings in rpm. That is standard. Once we have super strong solid metal or space age carbon fibers, we can achieve very high rotations. Let us assume that we can produce a flywheel that can withstand extremely high velocities. What will make it fly apart?
We are now left with Einsteinian space time type problems. We are also left with Doppler corrections to these problems. Linear space time has Doppler corrections and the same would be true orbital systems. The high velocity flywheel from a linear perspective would have a lower orbital velocity near the center and a larger velocity near the surface. Even without the Doppler effects, the center of the wheel will shrink but the outside of the wheel will shrink even more in the direction of rotation.
We then get Einsteinian type forces which press the outer surface closer together and force the entire package to shrink slightly in radius. This causes the flywheel to crack on the outer surface and fly apart. Thus even the best flywheel will be destroyed long before we reach near the speed of light C.
The Doppler effects when added to Einstein’s regular equations make the situation worse but it is sufficient to see that a variation of special relativity is applicable to a spinning wheel. What do you guys think?
I was taught that things set in motion like to travel in a straight line. Which can be evidenced by objects set adrift in space in some direction. They tend to fly in a straight path unless influenced by other forces.
The reason according to my teachings is that movement requires charging of the object, to allow it to travel through what ever medium it is traveling through. Kind of like a meteor creates a lighted area in front of it as it is traveling somewhat towards the sun against the solar wind. Everything according to old school teachings is electricity, the only sub-matter particle in the universe. Matter the hydrogen atom, is made up of a lot, an infinite amount of these particles of electricity. Held in a spherical shape by the formula for a sphere, Pi D^2 and Pi D^3÷6 the formula for the area of a sphere and the volume of a sphere respectfully. The ratio of surface area to volume of a sphere changes as you increase the size of a sphere. The very large surface area of a hydrogen atom, compared to its tiny volume gives ambient radiation the power to bombard the hydrogen atoms that make up all matter and maintain their spherical shape. These same formula limit the size of cell life on earth. By limiting the amount of food and waste that can pass through a cell membrane to feed the cell volume. When you over look these formulas and calculate upon a cube for heat dissipation you can find your reaction or process out of control, because the imaginary spherical shape within a cubical structure or tank, is the calculation despite the tanks shape.
If you try to deflect a small .22 caliber bullet you will notice that it can bend steel to maintain a straight path. Even though you may only be trying to alter its path by one degree. The bullet wishes to continue in a straight line.
The particles in the grinding wheel also wish to maintain a straight path, not a rotational or orbital path around the shaft that powers them.
That is why larger wheels have lower RPM's because the velocity of the material in the outer most part of the wheel, is moving faster than the area closest to the shaft driving the wheel. The materials in the outer most part of the wheel have more velocity, and therefore more potential power to continue in a straight path. Eventually with enough force to repel against ambient radiation holding the matter together, if spun fast enough.
High pressure, extreme velocity propulsion systems that use a Venturi to create thrust, can actually act like a gyro system, or fins on a rocket in the atmosphere, to stabilize the ship. The Lunar module used this Venturi method of propulsion, and it would stabilize the craft as it lifted off. Many nay sayers of the Apollo missions were convinced that there was no way a craft without air and fins could possibly accelerate at very high rates without losing control. It was the Venturi effect that allowed it.
Imagine a large flat roadway, 100 yards long, suspended in the center. And a car driving over the roadway. If you were to spin the roadway keeping it level to the earth, but rotating it either clockwise or counterclockwise, at the pivot point, as the car drove over that point. The car would actually screech its tires, loose traction, perhaps have to correctively steer the vehicle to keep it between the lines on the road, keep it moving parallel to the roadway. Things move in a straight line unless you apply another force to them.
