Hi folks,

I am wanting to model a rubber wedge, which will prevent one object from moving across another object.  I have a long metal bar, which has a sleve around it.  I have modelled the bar, sleeve, and also a wedge. 

My question is, how do i simulate the sleeve sliding down the bar, but then the wedge stopping it using its rubber frictional properties?

I hope i have explained this well enough.
