hanging geometry

Hello all,

I´m looking for some help for a "simple" Kangaroo definition.

I want to see how a geometry hanging to a rope is moving.

And how thick/heavy the shorter part on the left has to be to have the part hanging

parallel to the ground.

Is something like this possible in Kangaroo?

What are the best tutorials for Kangaroo to start with? 

Thank you very much.
