OK, here's the last explanation I'll give since this has drifted off topic, but please read closely. Thanks. Almost every solid, liquid, and gas shrinks in length, area, or volume when cooled. Water is no exception -- however, water has that little quirk around +40F (+4C) that I mentioned earlier. In general: temp down -> length down -> volume down -> density up It's as you cool from +40F (+4C) to +32F (0C) that the above general relationship fails. That's how water is fairly unique as a liquid. Let's examine that in more detail. As we fall in temp from +40F (+4C) to +32F (0C), the water expands, but what happens to the enclosure, i.e., the bottle? The bottle SHRINKS. Thus you have the outer enclosure shrinking as the liquid water inside EXPANDS. That's what breaks the bottle. It's the fact that you have two different materials with opposing forces causing a stress and strain. When the water freezes at +32F (0C), it becomes a solid. No longer will the water exhibit the expansion as it cools. The solid water (ice) acts as any other solid and shrinks as it cools. If you have any questions, please respond in Netmail or to mlogsdon@engr.iupui.edu. Thanks. --- QScan/PCB v1.19b / 01-0232 * Origin: IBMNet Connection - Indpls, IN - 317-882-5575 28.8 USR (1:231/1) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F5G00049 Date: 04/16/98 From: JOHN FAERBER Time: 11:07pm \/To: JOHN PUMMILL (Read 0 times) Subj: Engine Knock JF> Alternator, P/S pump, and the belt tensioner.

[----------^^^^ you said the above ^^^^-----------] With the engine off and belt removed, you should be able to spin the rotors or pullys and check that way. I would think it would become very apparent then. The belt tensioner should be free moving, very hard to move but not sticking or binding. You can place a section of thin rope or string and wrap around a pully and spin it quickly for a check if able w/o losing a kunckle. :) -_-_-Bill --- * Origin: Bordertown - Telegram from the Border (1:234/43) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F5G00051 Date: 04/16/98 From: BILL MITCHELL Time: 08:00pm \/To: MARK LOGSDON (Read 0 times) Subj: MC fuel tank ML> density is 1.043 or a ML> 4.3% difference in density.

No offense, we call that book smart engineering, we run across it all day, in fact fixing screwups caused by it provides a large portion of the work I do after all. This is the final thing I'll say about this. Fill a 2 liter plastic soda bottle with water, seal it by replacing the cap and tighten it. Put it in a freezer until frozen solid. When frozen solid there will be some sort of visable evidence, sometimes the cap may burst, other times the bottle may deform or burst, that the water expands when it freezes no matter what some text book on a shelf calls it. And in the example of the MC tank, that's all that matters. And since considerations about freezing the contents was the question, the behavior of water at any temperature beyond the range from room temperature to freezing is extraneous. In that range, liquid water will have no effects worth any concern. BTW, I was way off with my 11% guess, it was based on the fact that 8/9 of an iceberg is submerged (I forgot that the berg is fresh water, the ocean is salt). Thinking about this, though, there is probably a way to actually pop out such a dent using water, I wonder if it would work. setting it up might be harder than some other method, though. Seal the tank, it should be empty of liquid but full of air at normal air pressure or even slightly above. Place the sealed tank within an enclosure, such as another tank, and fill the larger enclosure with steam. Seal the second enclosure and allow the steam to condense. The resulting drop in pressure within the larger tank, external to the dented tank, might pop out the dent, though it might cause the larger container to implode. A version of this is actually used in an amazing paintless dent remover scheme. Then again, he's already popped out the dent by spot welding a bolt to it and using a slide hammer to pull on the bolt, which reminds me, I actually had a spot welder that was used to spot weld hook gizmos to sheet metal to acomplish just that. After the repair the hooks easily grind off. --- * Origin: The Verplanck Point mitch@magsystems.com (1:2604/539.11) --------------- FIDO MESSAGE AREA==> TOPIC: 246 AUTOMOTIVE Ref: F5G00052 Date: 04/14/98 From: ROY WITT Time: 07:42am \/To: JOHN FAERBER (Read 0 times) Subj: Engine Knock On, 14 Apr 98 at 00:32, John Faerber was overheard shouting over the engine noise, saying something to All about "Engine Knock",: JF> 88 Toronado V-6 3.8 engine.

The reason ice floats (and I might be wrong about the 11% figure, that's just an estimate) is because ice is less dense than liquid water. It's why engine blocks will crack if frozen. Why most containers will bulge or burst if the water contents are frozen. Take a half full container. Chill it below freezing in a freezer. Ice will usually for on the top of the liquid, and sometimes it will freeze hard enough to create a seal. As the lower liguid freezes it may then burst the lower portion of the container, even if the cap is loose or even off, if it freezes fast enough. Heck, take a two liter plastic soda bottle, fill it with water, cap it and put it in your freezer. Examine it tommorrow when frozen solid. But even if the bottle does not burst, ice will force itself out of any opening because ice takes more volume than water, mass being equal. --- * Origin: The Verplanck Point mitch@magsystems.com (1:2604/539.11)
