Ehrenfest paradox
name
(physics)
A
relativistic
paradox
concerning
the
concept
of
Born
rigidity
within
special
relativity,
where
an
ideally
rigid
cylinder
that
is
made
to
rotate
about
its
axis
of
symmetry.
The
radius
R
as
seen
in
the
laboratory
frame
is
always
perpendicular
to
its
motion
and
should
therefore
be
equal
to
its
value
R₀
when
stationary.
However,
the
circumference
should
appear
Lorentz-contracted
to
a
smaller
value
than
at
rest.
This
leads
to
the
contradiction
that
R
=
R₀
and
R
<
R₀.

(physics) A relativistic paradox concerning the concept of Born rigidity within special relativity, where an ideally rigid cylinder that is made to rotate about its axis of symmetry. The radius R as seen in the laboratory frame is always perpendicular to its motion and should therefore be equal to its value R₀ when stationary. However, the circumference should appear Lorentz-contracted to a smaller value than at rest. This leads to the contradiction that R = R₀ and R < R₀.
