<pre wrap=""> You guys do ! And quite frequently. Ok...in the context of rib

that in that context do nothing but resist crown and offer no support against
downbearing, can at the same time not only make the panel stiffer (which makes
it harder to press down.. hmmmm ) and not only that but makes the system
increasingly stiffer (even harder to press down) as more downbearing is
applied.<span

how to explain a principle in words you can't possibly dissect and
render other, unintended meanings to but we're also supposed to figure
out how to do this in a way you can't possibly take out of context and
render other, unintended meanings to. OK. I think I've got it. Of

asked a question... which you havn't answered but instead respond to
with the above. I didnt say there was two opposing positions... I said
precisely that I was sure it was me who was confused... but that I saw
an apparent contradiction, and asked for a clarification. So much for
the "there are no stupid questions" bit. </font><br>

<font color="#990000">Well... as so many times before.... a question
you apparently dont like just gets the ridicule treatment and the
average querier is left no more the brighter for the asking. I see two
apparently contradictory declarations about ribs in different contexts.
Sorry that bothers you. But a rib that in one context does not offer
any support against downbearing cannot turn around and suddenly offer
support just because the context changes. Either the ribs offer some
support (in some usual sense of the word) against downbearing or they
dont. You've said time and time again they dont. Now you say that ribs
in a compression soundboard increase stiffness in the board and do so
in the face of increased downbearing. Since increasing stiffness is
rather synonymous with providing support in the face of downbearing
... it seems reasonable enough to me to raise the ol confused finger in
the air and ask a question.<br>

<pre wrap=""> No one talks about "the panel trying to straighten out the ribs" because it doesn't work that way. Have you ever handled an edge-glued spruce panel? Sure you have. Just how much straightening is that thing going to do? </pre>

<div>What I see is two pieces of wood that are forced into a curved
condition against their better judgement... and both... would return to
being flat if they had their ditthers about it. Why would the rib be
pulling on the panel to straighten it out, and not the other way around
in equal amounts?</div>
