About my question on viscoelastic coefficient for human finger joints
and a dynamic model of it:

> I'm a phd student at Univ. of Pavia - Italy
> I'm working to simulate the natural movement of an artificial human
> finger.
> The question: preparing the dynamic model I am not be able to find
> indicative values of the viscoelastic coefficient of the cartilagineus

> finger joints (MP, PIP and DIP)
> Is there any study on this? And on the inertia, weight and other
> parameters of phalanges?

I've received these two answers and references:

"What is the formula for the journey to the ultimate meaning of reality?

Living the real.
The only condition for being truly and faithfully religious is
to live always the real intensely, without negating or forgetting
