Rubber (1.0) on ice (0.0) would still slide that's why I use the multiply

> 1) having a lookup table for all combinations of surfaces
> 2) averaging values (1st mu = 0.1, 2nd mu = 0.9, collision mu = 0.5)
> 3) multiplying values ( 1st mu = 0.1, 2nd mu = 0.9, collision mu = 0.09)
> The first is impossible for me, since I won't know what all the possible

> So between averaging and multiplying, what gives better results?
> Is there some other method? (taking the max/min for some parameters?)
