[edit] Neck weak points

The article makes claims about two weak points at the neck. These are reasonably well supported by standard rigid body physics. The claim that the weakest point is only 1/3 as strong as the rest has no evidence at all and needs a citation. How do you know it's not say 95% as strong, or only 5% as strong? —Dgies^t c 23:33, 3 January 2007 (UTC)

Does a stone have 50% chance of falling up? A moderately rounded corner typically has a stress concentration of 2, and it is reasonable to assume that the welt further weakens the glass by 20%, the original article thus made the valid claim of an approximate strenght reduction of 70%. Engineering is afterall the art of reasonable approximations. To avoid any discussion I changed the text to significantly less than 50%. Frank van Mierlo 00:44, 5 January 2007 (UTC)

Yes, but to extend the analogy, what you had before was like "Gravity pulls stones down, therefore stones move downwards about 99.9% of the time". You had <undisputed qualitative fact> → <quantitative conclusion> —Dgies^t c 01:08, 5 January 2007 (UTC)

The original text said: "approximately one third of its original strength". It appears we have reached a happy compromise. Best wishes for 2007 and do keep up the editing!! Frank van Mierlo 01:29, 5 January 2007 (UTC)

[edit] Lip vs. collar?

I believe the specific part of the bottle struck by the saber would be the collar, rather than the lip in general. See http://www.blm.gov/historic_bottles/morphology.htm and http://www.blm.gov/historic_bottles/finishes.htm . The entire "finish" of the bottle is removed during sabrage. I will leave edits to someone more familiar with Champagne bottles in particular... --Dfred 00:13, 7 January 2007 (UTC)

A good point I agree that "lip" leaves something to be desired. Given your suggestion I replaced lip with collar twice in the first paragraph. Have a read tell me if you like it better. I do not know what word would better be used to describe the thicking of the glass around the cork however. Suggestions are welcomeFrank van Mierlo 02:11, 7 January 2007 (UTC)
