I am trying to find a line that crosses in between two circles and is tangential to both. To help visualize, imagine a conveyor belt passing between two rollers. I have attached an image to explain it properly.
I know the radius of each circle and the distance between them. The problem is that each tangential point is determined by the other, so it seems it would be solved using a simultaneous equation, but I don't know the mathematics to work this out.
Any help would be appreciated.
