Hi Folks, Just wondering about materials for roller on roller or balls =
on plates. I know the limitations of glass, but a question about its =
smoothness, is the surface of glass as smooth or smoother than these =
hardened and polished steels?
My second question is one of friction: If you have one ball on one =
plate you would have one point of friction. If you have one ball =
resting between two rollers, ( in the V) you would have two points of =
friction, but the load would be divided, because its resting on two =
points, so is the end result of friction loss the same???? =20
Thanks, Ted
