Nope, you just passed my test. Great job, but your explaination could have
been a bit simpler by pointing out the torque vector is an imaginary
convention (the forces involved in it are orthogonal to the vector which is
a result of cross product operation), whereas thrust is a real force. Well
done Ian!

Tell you what, hold out your arm, I'll clamp a 48" monkey wrench down on
your wrist, then we'll hang a 30 pound weight at the distal end of the
wrench, this will produce an "imaginary" torque of 120ft-lbs on your
wrist. Then you can tell us if it's a real thing or not.....
