I'm confused... I don't quite see where this paragraph fits in with proving that there will never be more torque if you put the motors through separate gearboxes. Maybe it's just me only having a highschool physics background, but are some of the words taken a bit out of context? maybe a diagram would help me? I understand the terminology, this paragraph just confuses me.


But then again, maybe it is because it is 2:30 in the morning.
