    You need to have some sort of information on the areas.

    Which is funny because he has lengths which aside from buckling don't seem to serve any purpose.

    You didn't give the areas, but by my calculations, it looks like the ratio of the areas of the two cylinders is 7/16. Is that right?

    Let's see what you've tried so far and maybe we can spot your error.
