Determining the curve



Hi, I hope someone can help me here.

Where I work I use a roller to role a flat plate of metal into a curve.
The roller consists of three cylinders, A, B and C. A sits on top of B
and both are fixed. Cylinder C sits to the right of A and B and can
move vertically. The distance between the centre points of A/B and C is
80mm. The diameter of each cylinder is 74 mm.

So, a flat plate is fed in between A and B. It hits C at an angle
relative to the position of C along the vertical axis. This then rolls
the plate into a curve which in the end curves to form a circle.

What I want to do is put a scale along side the cylinder C so that I
can set it to the correct vertical position to create the circle I
want.

So, my question is, can anyone think of a formular with one variable
'd' that I can plug the desired diameter in and get the value 'Y' (the
vertical position of cylinder C)

thanks for any help,

Steve
