Dual resonant eccentric flywheel

Every bit of what you need is in the links I provided, mostly in the first one. If you think that is crap and useless examples, you are really REALLY going to have trouble finding a "physicist" who will give you the time of day... because each one will have worked through all that stuff as an undergraduate, will understand it fully, and will expect YOU to have done your own homework and also to understand the basics of inertia, torque, moment arms, energy storage in flywheels and all the rest of the "crap" that is in those links.

But of course you don't want to do homework, you want someone who HAS done homework to tell you the answer, and if that answer isn't what you want to hear... you will proceed to call it "crap" without even bothering to understand how the answer was arrived at.
