A = Angle Of Rotation
B = Rod Size
R = Crank Radius
CHANGE THE VALUES BETWEEN "..."
A = "X"_Rotation*180/pi
B = "30"
R = "10"
(B+R)-sqrt(B*B-R*R*sin(A)*sin(A))-R*cos(A)

Never mind. I just realized that I can do it with limb-solver.
A more complicated problem.

Hi, Henrique. This is a great tutrial. I really wish I had seen it a few years ago. It would have helped on a couple projects I've had over the years.
Anyhow, I have a similar but slightly more complex problem that I am seeking help on. See this video here. The only objects that have keyframes are the wheel and the front stirrup supports, the rest follow via look-at controllers. But I would love to simplify it, and wire the front stirrup supports to automatically rotate the proper amount with the wheel. Can you help?
Thank you.
