My question is to find alternative solution.

Hello, I would need mechanism which can do two motions, one rotation for 90 degrees or more and then vertically for few milimeters. Is there some idea, something like this Here is image of what I mean. http://imgur.com/nycnGeO

but what is F2?

Can you draw me whole loop?

Alright, I did it like this, but I don't know is it the right way. I put a virtual mass on point A and that mass goes to 0. ( http://postimg.org/image/nowbzvj6p/ ) After that I got equation like this ( http://postimg.org/image/a1r3vm417/ ) and I put that x2 to the first equation..

Alright, I know what you mean, but how will I draw a loop to apply mason rule, I get confused when I need to put x2

So, I try with Laplace then?

After I gotten this equation, I tryed to excrete x1, but I'm missing one equation to make a state space model. I think I need to get matrix A 4x4 and I don't know how to get x2 double derivate when it doesn't exist, if you know what I mean.
