- I would like an explanation of the physical model for a roulette wheel.

Hello,

I am having trouble understanding the two friction force terms from the ball rolling on page 4 of this physical model: http://www.dewtronics.com/tutorials/roulette/documents/Roulette_Physik.pdf

What is the reason for the [itex]cos\theta[/itex] term ?

I think the frame of reference is made up of the weight vector and the centrifugal force vector,but the tilt angle epsilon is shown page 15.

Thank you.
