Oh and @
DSLeach,regarding the MOI and rotational inertia thing?
I have a 'rough' idea what is going on.
In fact I began modeling the entire rotating assembly and drivetrain in solidworks, but could not obtain the weights of enough of the individual components so I gave up:
I model in Onshape when at home and can import the models into SW at work.
And since I guess I have to defend my credentials when challenged on it:
I am a Principle Test Engineer/Staff Consultant at one of the most advanced environmental test facilities in the country with over 20 years experience.
My office is in the
dynamics lab.
The item I am currently in charge of testing costs more than a nuclear submarine.
But I have learned to not lead with that.
