Thanks Clem! Interesting paper. I don't know how I missed it.

For grins, I checked your analytical solution to eq_14 using my favorite* CAS, Maxima. I got the same answer as you, but I don't like the way Maxima factored it [see attached PDF]. What CAS did you use?

You modeled the gearbox by using a constant parasitic torque. I'm looking for something just a bit more realistic.


*it's my favorite because it's free and therefore anyone can afford it:-)
