Thanks Augi!
I'm making an excel spreadsheet to analyze (and eventually optimize) a specific type of 4-bar linkage. I always have one vertical link, and, for the purposes of the analysis, I step the bottom link in 5 degree incriments.
What I'm doing is using intersection of two circles to enforce compatibility on the floating link and the top rotor, by 'drawing' a circle with a radius the length of the floating link at the end of my bottom rotor, and 'drawing' a circle the length of my top rotor at the top of my stationary link....thus finding the point the links interesect. That's about all I can say without an NDA, but if you're more curious, I can PM you more detail about the specific application as thanks for your help
