Q: Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.: I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.

Q: I don't understand why or how they still exist. I know I'll get some answers saying they're part of the food chain but what animal on earth would get a sufficient meal from one of these?: Your question is one for philosophers or priests because it is a question about purpose. Scientists never ask the purpose of anything, they only ask about functions. There must be thousands of animals that eat crane flies: Fish, bats, birds, robber flies, spiders . . . the list is practically endless. I'm not sure I understand your question about how they exist. How does any living thing exist?

Q: My fiance and I would like to make 1,000 paper cranes for our wedding next year in May. We are looking for a good type of paper to use for this. We are not too particular on the color of the cranes, though we like blue or gold. Does anyone have any feedback on the sort of paper I can get for this project? I know there is origami paper I can buy, but I was wondering if that is the only option I have to choose from. Thanks in advance! :): I okorder Hope this helps!

Q: I live in the upper stairs of this apartment with a huge light right next to the front door, and a bunch of Crane Flies kind of hover around it. So whenever we open the door, some of them come in, and it's a big problem. Especially to a someone like me who's deathly afraid of big bugs.So we want to buy the Raid spray, but we don't know if it would work. The Raid: Ant and Cockroach spray didn't work that well, but that's understandable.sooo anyways, has anyone tried the Flying Insect Raid on Crane flies?: Crane flies do no harm whatsoever, so what you're proposing will replace the total lack of harm that crane flies do with the potential harm of adding more pesticides to the world, plus the byproducts produced in its manufacture and the garbage the can represents later. Is this really worthwhile? I would suggest you look into getting a yellow bug light, it's quite possible that a different type of bulb than what you're using now might be much less attractive to crane flies. If not, addressing your unreasonable fear of insects would be a safer solution.

Q: Who is the most gruesome Stefano DiMera or Alistar Crane?: Stefano

Q: I just seen pics of a crane fly and not sure if I see crane flies in my house or mosquitos now. And do crane flies bite?: Really easy: A crane fly has no long piercing mouthpart: they feed mainly on nectar Female mosquitos have long piercing mouthparts, males are smaller and have shorter mouthparts for sucking nectar from flowers. Common crane flies are almost always bigger than a mosquitos.

Q: First Summary gets best answer...thanks!: Manslaughter charges come about when it involves death, caused by negligence on someone's part - either the operator, the owner of the crane, the contract, etc.

Q: I was wondering how those guys/gals get up to their posts. Is there some type of elevator or do they climb up everyday? I'm talking about those big cranes on contruction sites. the huge ones.: They climb a ladder up the middle of the central tower. I saw 'it' on the History Channel. .

Q: I will soon have folded my 1000th paper crane. What should I do with them after I am done?: i don't know if you are into photography but what would make some really great pictures is take all those cranes and set them up in random spots around you town or area and photograph the group at diffrent angles. you could have lots of fun finding unexpected places to put them. and you would end up with a really great portfolio series

Q: I read a book a year ago about sadako sasaki who tried to make all 1000 paper cranes to live. Do you have to keep saying your wish over again when your making them, and when you finished making all 1000 how long did you wait until your wish came true??: you make your wish once your done cause you only get the wish if you have 1000 cranes right so saying your wish when you only have 6 won't do anything. it can come true the next day till the next year or ten years it not something definite. I've never made 1000 but I think I will.
