The Milliken textbook gives the formula for braking force as follows:

I've tried to find what A_x is but can't :/ Does anyone know?

This is used in the context of deriving anti-squat from first principles. I need to understand it from first principles so I can figure out how to adapt anti-squat to a 4x4 vehicle.

Thanks

Acceleration in the X direction, i.e. in the direction of travel.

N.B. That "g" is in there because of the chosen unit system. In SI units, F = M A and that's all there is to it.

Thanks. The "g" totally through me off. I'm only familiar with SI units.
