dynamic simulation cinematism....unknown force!

[Massy84]

Good morning to all, I have a nice problem to solve with inventor 2010: within a project for the university, I have a particular cinematism (a 7-light hinge) lying (thickness aside) on the x-y plane. I have to find out what couple I need in a particular revolution joint, to move all the cinematism to which a force is applied in direction z. I saw the simulation that had made a user of the forum, setting with the command "unknown force" the couple incognita to be found in the joint but, while inserting the frictions in all the other joints of the cinematism (rights both prismatic and revolution), the graphic output the simulation of the movement of cinematism by imposing a law of movement at the usual revolution joint works without problems

Am I wrong?

Can you link the other user's simulation of the forum?
