Apparatus:
masses,
inertia
machine
Description:
Run
the
string
and
mass
over
the
pulley
and
release.
This
causes
the
moment
of
inertia
demo
to
turn.
This
spins
quite
quickly,
so
keep
digits
out
of
harm's
way.
The
bobs
on
the
arms
translate,
so
put
them
in
many
positions
to
show
moment
of
inertia
and
radius.
PIRA
Neglecting the mass over the pulley, this apparatus may be used to show the dependance of the period of oscillation on rotational inertia and r.
