Anyone knows how to calculate the angles of such a 5 bars linkage:
Graphically it's relatively simple (intersection of the locus of a 4 bars linkage with the circle of the 5th bar), but analytically it's another story...
The problem surfaced when modeling top support of the boom of 42042 crane B-model that uses this kind of structure

I'll probably use a successive approximation method, but if somone has a better way...
