Re: Banked road



To simplify assume tham M>>m so that the pipe is at rest in
my frame of reference. I see only one force acting of the
car; it is the CENTRIPETAL force toward the center Fc=m*v^2/r.
It is the normal force, N, with which the pipe acts on the car.

The car acts on the pipe and the pipe reacts with an equal and
opposite force. If the reaction is real (not fictitious) then
the action is also real in my frame of reference. We need a
name for the force with which the car acts on the cylinder.
What is wrong with CENTRIFUGAL?

I think the word centrifugal is already used, for the case of analysis in a
different frame of reference then your frame (the fixed stars). That is,
use of that word violates your admonition to not use a word already used.
Why not call that reaction force the *normal* force of the wheels of the car
acting on the pipe?
