strains on catenaries
some people are having a tough time with the meaning of the word catenary, and
are thus leaving themselves open to serious damage to their boats when anchoring. http://www.du.edu/~jcalvert/math/catenary.htm gives a rudimentary explaination of catenaires and the forces thereupon. take notice of the next to last paragraph. |

You're wearing those Speedos too tight. How would these forces affect a 30 foot chain? |

someone accused me of being an instructor at age 14, and I replied I NEVER
wanted to try to teach anything to idgits. How would these forces affect a 30 foot chain? shows my point. |

"This looks like a good spot to anchor. Someone fetch me a graphing calculator." Your best bet: wrap the anchor chain around JaxAsse's ankle and toss the chain overboard. -- We today have a president of the United States who looks like he is the son of Howdy Doody or Alfred E. Newman, who isn't smarter than either of them, who is arrogant about his ignorance, who is reckless and incompetent, and whose backers are turning the United States into a pariah. What, me worry? |

hoary, your miserably low score on your math SAT's is showing again. were out
a bit late the night before you took it?

no need. just remember -- as junnie can't seem to understand -- that once the
wind and waves pick up you MUST have a stretch in the rode provided by rode only available as nylon or plaited line (unless, of course, you have prior hung several or more 25# kellets in the middle of your all chain rode).

see, junnie, once again you tell us an anchor is REQUIRED to drag, or else
something breaks. the sorry thing is, junnie, your claim that dragging anchor is required. it isn't, *if* you anchor properly, and all chain ain't proper in wind and waves.

No duh, genius. I posted this same link about 5 times while you spouted on about your narrow and incomplete understanding of catenaries AS THEY RELATE TO ANCHORING. Not the least of which.... "This equation is integrated as shown in the Figure to find y'(x), and again to find y(x), using the conditions that y = y' = 0 at x = 0." and your immovable anchor conundrum.... all of which make this argument specious.

junnie, if you read it, how come you don't understand it? And if you
understand it, how come you post stating you don't?
