perpendicular axis theorem
Noun
uncountable
(physics)
A
theorem
that
states
the
moment
of
inertia
of
a
planar
lamina
(i.e.
2-D
body)
about
an
axis
perpendicular
to
the
plane
of
the
lamina
is
equal
to
the
sum
of
the
moments
of
inertia
of
the
lamina
about
the
two
axes
at
right
angles
to
each
other,
in
its
own
plane
intersecting
each
other
at
the
point
where
the
perpendicular
axis
passes
through
it.
Japanese Meaning
