I just I had a thought as to the original question in this thread. Regarding whether drivetrain loss should be a percentage or a constant.....
If the losses in the drivetrain are caused by friction, let's go back to what friction is.
Friction = coefficient of friction X Normal Force
If a 200 hp motor is making more force than a 100 hp motor, then the 200 hp motor also creates more friction as a result of this. Therefore, as power increases, so does the friction and the losses in the drivetrain.
In this case, it would seem that using a percentage would be correct. Maybe the question to answer is whether this percentage should remain the same or increase/decrease with more power?
I need to quit wasting all my thinking power on this thread...I have a test tomorrow I will need it for
