We may also have observed that, when we consider two
different forces
F1
and
F2
which act in, respectively,
r1
and
r2
such that
r1F1
=
r2F2
then the angular acceleration is the same,
whether we apply
F1
in
r1
or
F2
in
r2.
The only thing that matters is the torque,
not the intensity of the force or its position of application.
