Default Anomalous movement resistance in a spinning gyroscope



[Only registered users see links. ]

A symmetric harnessed gyroscope accelerated to a given spinning
frequency takes different time periods to stop, depending on the
direction of previous spins. For repeated alternating, anticlockwise
and clockwise spinning, the rotation period in both directions
significantly increases, which is not the case when the gyroscope is
repeatedly rotated in the same direction. Using the measurements it was
observed, that the time of gyroscope's rotation was significantly
lengthened or shortened, what indicates that it either increased or
decreased the movement resistance of the gyroscope. The presented
experimental results suggest the existence of anomalous movement
resistance and demonstrate that a fixed spinning gyroscope displays
unusual history-dependent movement resistance effects. The effect is
real, large, reproducible and does not follow from experimental errors.

The manuscript was reviewed thrice, according to the publishing
procedure in "Physical Review Letters" within two year. The remarks of
all the reviewers were taken into account during its correction.
Because the publishing procedure for our manuscript in "Physical Review
Letters" finished, we decided to publish it in Journal of Technical
Physics, J.Tech. Phys., 46, 2, 107-115, 2005.

Those effects strongly depend on material
(substance) of the rotor's disk, for example they are
great for the rotor's disk made in teflon and small one
for the rotor's disk made in plexiglas.

it is "memory" effects in a disk's material

We made measurements for different settings of rotor, for example the
spindle of the rotor was laid horizontally. The effect always exists
and is large. For the same bearings and the same dimensions of rotor
we have observed different size of the effects. The effect is small if
the disk of the rotor is made of plexiglas, and very large if the disk
of the rotor is made of teflon.
