Napkins !
Quote:
Well David paper napkins if they got slightly wet the legs would sink and the rocking would start again. Surely the restaurant could provide damask napkins that would do the trick. Hey Davy you are keeping me away from the Sri LankaIndia cricket match which is on live right now. Its a crucial match in the series and right now India is sweating to keep the score at a reasonable total which we could catch up with and beat. RGDS, Mally

But I suspect that that is an assumption that David failed to consider necessary. Although he didn't state it, I think that he expects the "four legged table" to be of a conventional configuration which includes a reasonable degree of symmetry and "feet" that extend sufficiently below their supports to provide the necessary concavity. Isn't it "a bitch" to describe the problem without ANY loopholes for the lawyers and mathematicians? :) (Note to xilman: REAL WORLD is implied.) Last fiddled with by Wacky on 20070323 at 20:42

For what factor base? :) OTOH, we all know that FLOOR is a step function. (As in "you step on the floor"?) Forget this thread Let's revert to "four on the floor". Richard Last fiddled with by Wacky on 20070323 at 21:02

Time to state my argument.
Rotating the table through 90 degrees replaces one of the diagonal pairs of feet with the other, so the rocking is on the other pair of feet. Somewhere in between, the rocking changes from one pair of feet to the other. At this point, all four feet are grounded. I have been applying this for 35 years with 100% success! (With the exception of Wacky's concavity condition or coplanarity failing). David Last fiddled with by davieddy on 20070324 at 06:15
