Trying to model the ball and beam problem

I am trying to model the well-known ball and beam problem with Modelica. Now I have struggle to model the ball rolling down an inclined plane depending on the angle. I intended to use the MultiBody libraray. Has anybody an idea how to handle that? Or has anybody dealt with a similar problem?

For hints and reference you might take a look at the simple vehicle model in the MSL translational package:

Modelica.Mechanics.Translational.Components.Vehicle

Check out how the inclined plane is implemented with idealRollingWheel to calculate gravity based acceleration on the vehicle. Slight modification of that should deliver what you require for your tilted plane.

MultiBody provides a Wheel as well, but since you are investigating a 2D scenario keeping things simple might be helpful.
