drivetrain loss????

[Hethj7]

Yea, I understand that there are many more variables than just "friction" within the drivetrain. We all know that the real world applications are quite different than those found in a book.

However, regardless of some of these other variables, such as driver or dyno operator, the basic question of whether drivetrain loss is a constant or a percentage should be able to be examined.

My reasoning stating that friction increases with force is just a stepping stone and obviously leaves some questions to be asked. But, I think it is good start as to why the loss may not be a constant, but rather a percentage. I am not saying it is right, but it seems tobe heading in the right direction.
