Kind of trivial isn't it? Draw a line from the center of the wheel to the edge of the flange. As the point on the wheel, along that line, that makes contact with the rail comes down, touches the rail and then goes back up, what happens to the point on the flange? You should be able to calculate the precise motion from that. |
