Air Conditioning Ductwork Making Noise?

Why do you believe it is coming from the ducting? you did not say if your A.C. is in the attic or the basement? I would start with looking while the A.C. is running and try to pinpoint where it is coming from. My guess is it's coming from the blower area. Most duct work has a canvas connection that stops most sounds. And in the blower area your moter is mounted in rubber grommets. Most likely it's metal to metal in the blower area. Good Luck

1. What are the exteriors of today's cars made of?

The body is made of metal and the bumpers are plastic. Just take a magnet to the part and that will answer your question

2. How does a thermometer measure temperature?

They also make the liquid thermometers with alcohol. It is safer and cheaper than mercury. Many common thermometers that are used outside the widow of home, etc. use the thermal expansion of metal. There is a circular spring that is attached to a needle at one end. As the metal increases or decreases in length due to changing temperature, the needle moves. Digital thermometers measure the resistance, which depends upon temperature, to the electricity running through a circuit. Hope that helps.

3. Where can i get the most money for my gold chain?

You would probably get the most from a reputable coin dealer. They will usually pay you for it according to what karat it is and how much it weighs in grams. You may get around 85%-95% of the spot price of a troy ounce of gold at any given time. Do not settle for anything less than 85%. But remember that the karat of the gold must be figured in first as well. The lower the karat, the more other kinds of metal have been added as an alloy. For example, 14K gold is 58.33% actual gold. The dealer is only going to pay you for the gold, not for the entire weight of the chain. Also not for the sentimental value, or the workmanship, or any gemstones mounted in it, or the fact that it might be a beautiful piece of jewelry. Try not to be too shocked at how little it might seem to be, but remember that retail jewelry stores have a markup of 600% or more, if that's where you got it. Those "cash for gold" places might pay you 30%-40% for it, if you are lucky. They are counting on you not knowing what you are doing or what you have. Good luck.

4. furnace creating a ground?

I am fairly certain it's against code not to have an electrical ground. However, your gas line should be grounded, and that is likely how the furnace is grounded. The reason it's dangerous not to have an explicit electrical ground is pretty simple: if someone is working on the gas, and has it disconnected from the furnace, and there is a short in the electrical wiring of the furnace, as soon as they touch the furnace and gas line, they become a conductor to ground, and will be electrocuted. Any type of electrocution where the current passes through your chest is incredibly dangerous: as little as 100mA can cause fibrillation (requiring a defibrillator), and >1A typically causes permanent damage. As Shimon points out, it's also possible that it's inadvertently grounded via duct work, though ducts are not explicitly grounded so that is unreliable at best. Again, same sorts of dangerous here, and if it is inadvertently grounded (eg: somewhere a piece of metal is touching both the duct and something else grounded), it's likely to become ungrounded at some point. I highly doubt that it's grounded on the cement floor to the point you would get 110V, as the resistance is likely in the megaohms, and so even if it was being grounded that way, you would likely only see a few volts if you measured

5. What is the worst incident that occured during your time in prison?

To me or to someone else? Because I seen some baaad stuff happen to other people but the worst would have to mean something that happened to me because... well, frankly, it's way f^*%ing worse to have something mildly horrible happen to me than it is for something seriously catastrophic to you. Dig? So, seeing a guy in a wheelchair... a wheelchair for Christ's sake.... get his jawbone blown off by the tower with that mini about 20 yards from the action on the yard wasn't half as bad as me going through some mild knife play. So here's the worst:Getting blasted in my rib cage by a backstabbing cunt (pardon my french). Left-handed, he hit me from behind as I was moving my property into a new cell. You ever have that feeling like your teeth slip against each other and it makes a skrrreeeek that reverberates through your entire skull? It was like that except it was metal slipping against my favorite rib. That was the sound and feeling of my life being saved, because if that chump hadn't glanced his shot off the bone and actually managed to slip it between the ribs... like they say in Hollywood, "that's a wrap".As it was, I recovered and was able to turn around and punch him. We fought for a bit until the tower hit his button and they sprayed us. I actually came out of it okay that time. I've been hurt worse than that before, but that day was terrifying. That sound in my body of metal and bone... I shiver still when I remember it. I've been physically injured far worse than that, but I've never been as scared as I was that afternoon. And that's what makes it the worst incident... the body heals, but that feeling... that feeling will never go away.What is the worst incident that occured during your time in prison?.

Oil Under Basement Floor Covered by Metal Covers?
Oil under basement floor covered by metal covers?Since it is in the basement of the house, it probably is not a sewer septic tank. However it does sound like a septic tank, possibly used as a water cistern. No way to know for sure. When you find out, let us know, Wow, the plot thickens. This certainly is one of the strangest things I've ever heard of on Y/A.Very weird, but really interesting as well.— — — — — —What can I do about my deteriorating basement floor with a large hole that seems to go right through to clay?Well, lacking a picture for now (try it again, please, and do not delete the link text it puts in on the bottom - that wo not show up in your post, but it will let us see the picture) If you have a concrete floor now, you can break out bad concrete until you get to good concrete, put in some crushed rock for a sub-base and pour new concrete. Depending what is going on, you may want to break out some more floor and install drain pipes and a sump pit before you backfill and concrete over it. Avoid getting too close to walls, chimneys or columns/posts when breaking things out, or call in an engineer if it seems like you need to. OK - the lower bit of concrete with the tidy corner is presumably a footing - so do not mess with that. The floor, you can basically do as described above - cut back to a sound edge and fill in with fresh concrete, or fiddle with drainage as seems appropriate. Many older homes were built with dirt -floored basements, and a concrete floor was an afterthought, often poorly done on the cheap by some later homeowner. If you just want to plug the hole, see above. If you have higher aspirations for your basement, describe them and we will give it a thought— — — — — —What can I do about the smell coming from the drain in our basement floor?The drain is not getting enough water to keep the sewer gas out of the house, especially in winter— — — — — —lots of dead Millipedes Worms on the unfinished basement floorThey just sneak in when you are not looking. You probably have spiders and silverfish too. Just try not to scream the first time you see a silverfish, they are very creepy.— — — — — —Repair a Crack in concrete basement floor?Urethane is a great product to seal cracks in concrete. It is used on brick and cement exterior surfaces such as walls and sidewalks. It sticks to practically anything and stays in place through movement expansion and contraction. I am not familiar with the product that you've asked about but it very well could be made of urethane or a similar material— — — — — —can anyone offer advice on products used to paint a basement floor, the floor is concrete and not insulated.?Epoxy, the stuff used on garage floors— — — — — —i was wondering best way to connect wall made with 2x4's to concrete basement floor?You need to glue it and use a small lead or plastic drive in anchor.Get a masonry bit and an anchor to match at home Depot or wherever it only has to go into the concrete little over an inch,it wont crack and will be a much nicer job. Good Luck— — — — — —What is this pipe coming out of the basement floor?The way I can see it that looks like a 2: gal pipe with a 2: cap I think it was for a oil drum at one time for a oil furnace. Back in the day they did not use black pipe for a oil burner. Or it could be a waste line of some kind cut the pipe and check and also you can smell what it is.— — — — — —Price quote on concrete basement floor?Ask at a local builders supply place. They are the ones selling the concrete and they can give you figures— — — — — —Who should I hire to remove linoleum tiles on a concrete basement floor? Who does this kind of work?A flooring specialist. They usually do linoleum, tile, carpet, etc— — — — — —How do I install base cabinets on an un-level basement floor?they have that flooring board that they put under the tile. i think it is called sub floor. that is about 1/2 in thickness and may do the trick for leveling out the 1 inch problem. if it is a gradual decline of 1 inch across the floor then i recall some handy man floating my floor. he just put some stuff like plaster or putty and made sure the floor was level across the surface. it did not take long and the floor was level. it also was not able to be detected
