For ease, http://www.geom.uiuc.edu/education/math5337/linkage/linkage1.gif for reference.

Can anybody tell me what comparatives lengths k, m and j should be to get the most possible movement for Q? That is, how would I need to set this up so that a line drawn by movement at point Q can be the longest achievable for the length of parts used?

ie - if m were very small, you wouldn't have much movement, even if j and k were very large. if j were very small, you would have a similar problem.

I'm guessing the diamond formed by the m pieces would be completely squashed one way while the is 'at rest' (centred), and completely squashed the other way when at either of the limits - even though this may not be practical in a real application.

:S

RE: Peaucellier Lipkin

If you google virtual mechanisms, I think you will come up with some inputtable "calculators" that can show you the various movements.  Did some mechatronic displays a few years back and I had a website link that was invaluable for the various movements.  It's no longer in my favorites, but I'll post it if I can recall the site.

Thanks Norsk. I'll have a look around.
