If we have two steel tubes (as in a seatpost and a down tube) and slide one inside the other; how
much overlap is needed before maximum strength is attained? I'm guessing it has something to do with
the diameter of one of the tubes...

I seem to recall the minimum insertion point to be 4X the OD of the smaller tube, but don't ask me
where it was read/heard/learned because I don't know.
