Downbearing, in such a configuration, cannot be measured by any of the
conventional methods. I'd be curious to know how it was set to
being with. Whether upbearing (or pulling) can exercise an equivalent
force or load (compression / tension) or stress as downbearing is, as
yet, not determined, I think.<br><br>
