<span style="color: #ff0000">Hi again HighPlains,
I do no wish to change the format of the posting so I think I can use red color to distinguish your text versus mine.

Zor,
Two objects can weigh the same, but the force it takes to accelerate them to the same angular rotation varies based on the distribution of the weight. Think dumbbell, with the weight on the end vs same weight concentrated at the center. Low polar moment, though I guess being from Canada Polar might have a different meaning.
<span style="color: #ff0000">If you read back in this thread you will find that I already covered this subject when I referred to mass distribution in a model. my recent comment was to avoid putting my own words in your mouth
. Of course you are correct and I had already covered that very same subject.

Sorting ribs by weight puts the heavier ribs in the center of the wing if constant chord, but even when tapered, you can balance a wing with careful selection of which panel each pair of ribs go to. Same with all the other pieces that go in the wing.
<span style="color: #ff0000">I wonder how many understood what you implied by "balancing a wing". Thanks for your present explanation.
Considering the weight of the ribs in a wing vs the total wing weight, you are correct but the result is not going to be very significant. Your idea can be carried further by finding out which end of the spars is heavier to orientate the spar with the heavier end at the root of the wing. The same could be done for any sheeting. Again the result would not be very significant and doubtfully observable by even the expert fliers. </span>
Probably a good indication that I am "one of those that frankly never will".
Dirty Harry said it best - "a man's gotta know his limits"
<span style="color: #ff0000">I have no objection to laugh at myself. I know my limitations and realize that "I do not know it all" thus the urge to keep studying and learning more. I am willing to admit that everyone else knows more than I do. For sure many in this forum do; even the odd one that wrote that Zor knows nothing and just repeat what others are writing. Any reader can makehis/her ownjudgment on that.
Things I avoid discussing in the forum ___people's characters, personalities, knowledge of others, politics, religions, sex. It is unfortunate that in many cases we cannot disagree with some individuals on a technical matter because they are offended if you do not fully agree with them. Offending is against the rules of the forum but being offended depends purely on the reader although the writer will be the one penalized. Does not that sound a bit illogical? IfI respond defending my characteror personality then I am the one penalized? It does not make sense. But then the writer may also have been a moderator with the capability of penalizing someone.
Considering the large number of readers that are not participants but read these forums to extend their knowledge and find help; should we let them be mislead by a fair amount of misleading information written in the forum?
