If you're trying to measure centrifugal force ANYWHERE, then this implies that there is some rotational motion about some center. Then to measure it, you can use ANYTHING, like a bathroom scale, against an object where you put the object, the instrument, and the center of motion in a line. > > 2.

Is that the best you can do? Of course I've heard of inertia. Relevance? Mark L. Fergerson

Herb's point was "artificial gravity" in large, *artificial* structures, to avoid needing expensive bathroom plumbing capable of zero-g operation. Try to keep up. Mark L. Fergerson

Fergerson I wasn't responding to his point, whatever it was. You said: "Idiot. 2001 was *fiction*. Large rotating objects need large bearings, and *balanced loads*. Keeping the load balanced will be a problem if anything moves." I was just pointing out how silly your statement was. Try to keep up. |
