We start by hooking up 2 electric motors

We spin the motors up and because
they oppose each other and the motors
are linked physically nothing happens when they
spin.

We place the brake calipers at the point
the rotors are the closest and also link them
physically. We hit the brakes hard.
What happens now?

Sorta like such but not the same,
Using a brake can enhance the "kick" it will give.
and If you use 2 brakes on a single rotor and time
the correct braking times you could actually get linear
motion (irradic though) impulses out of it also.

Look at pulsing a brake at twice the rotation frequency.

Abstract:
Orbital angular momentum exchange, both in cavity
free stimulated parametric down conversion and in
an optical parametric oscillator, is studied. In both
cases, the conditions for parametric amplification are
discussed in terms of the orbital angular momentum
exchange between the interacting fields. It is shown
that in cavity free parametric down conversion,
parametric amplification is conditioned to conserve
orbital angular momentum. However, for parametric
oscillation, cavity and anisotropy effects play a crucial
role in the orbital angular momentum exchange between
the interacting fields. >>

Sue,
You are totally ignoring the experiment given

Yes... nearly. >:)

and
replacing it with a link that is not the same.
I am talking about 2 different brakes in different
locations on the rotor setup.
It is not the same as "pulsing" one brake.

Study what a child can do by shortening
the length of a swing chain at 2f then
tell us what flywheel brakes pulsed at
2f can do.

Similarly a spinning skater can increase
the rate of rotation by swinging arms
in and out at 2f.
