Q:Does anyone which direction (N,S,E,W) a construction worker will leave a crane facing at the end of the day?
Like 2 others said... if the predicted winds are to be higher than, say, 25 mph, they would point the crane into the predicted direction of the wind. If there are no high winds predicted, then it doesn't matter, BUT, they would probably point it in a direction that would do the least amount of damage should the crane support fail, for whatever reason. OR, they might leave it in position over the loading area, so they can begin picking up immediately the next day. .
Q:Cranes can be operated by all of the following except:?
Crane are extremely dangerous and complicated machinery , the operators need intensive education and training , they have to pass the required tests to be certified . Now even the signal guy on the ground who helps the crane operator needs to be certified . So your answer is A.
Q:Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace..?
You would mean one in the hearth, yes. An older term may be to call it a Pot Crane or Chimney Crane. That is most common to what you describe that it is affixed to the chimney and swings about. That does not swing, a lug pole might be from a green wood or iron hung above the fire with chain ... or if a Hearth Crane then a standing legged trestle (stands upon the hearth) and hooks affixed ... some with a pot crane attached. But either. You might also refer to it with it's counterpart, the trammel ... as in crane trammel. The trammel is the device hung from the pole or crane to allow the pot to be adjusted up or down depending on the heat required. In some cases the trammel can be just a series of S-hooks linked together, it can also be a chain with hooks, and is often a specific toothed device wrought by smithy. As a child we used hooks and hooks chain, thoe as a man I owned a sawtoothed trammel but hardly used it as I'd obtained a stew stove. My business partner Ebenezer insisted that a toothed saw trammel was frivolous and kept a chain and hook type in his home.
Q:Mosquito Eater (Crane Fly) Problems?
Mosquito Eater... That's interesting lol. I grew up calling them candlestick bugs. In any case, crane fly populations can explode when they have plenty of resources and few predators in the larval stage. It's possible that there is a shortage in invertivores (animals which eat invertebrates, such as insects or crustaceans) that provide top-down population control in the aquatic environment from which your population came. These insects are harmless and provide food and energy to myriad other organisms in their food web. For that reason, I suggest that you just catch them and take them outside. We get huge ones around here (Western Kentucky, think 2.5-3 inches from head to tip of abdomen with a good 6 inch leg span haha), so I wouldn't suggest squishing them in the house on the wall or anything lol. If you're really bothered by them, I don't really have a non-messy solution. As a biologist, I kind of just ignore them. Also, these animals are attracted to light. Maybe turn off your porch lights, if you have any, and keep your doors closed?
Q:what does Stephen Crane mean by this ?
This is a very critical and harsh poem. Stephen Crane seems to have a more pessimistic outlook on life than other poems he has written, and nowhere else does that pessimistic outlook come through in his poetry than here. The pattern of the poem affixes a cynical, satirical statement after every statement of War is kind. For example, War is kind, Hoarse booming drums of the regiment, little souls who thirst for fight, these men were born to drill and die. The unexplained glory flies above them. Especially when Crane says the unexplained glory flies above them, he is making a powerful statement by questioning whether all the death and destruction is really worth it. This questioning is very important, because many wars are not really for what they seem to be for. There are exceptions of course, perhaps World War II and the fight to end the holocaust, perhaps the Civil War and the fight to end slavery, but for the most part, wars are usually conflicts between cultures over natural resources and disagreements over cultural values. The glory of war, the patriotism, the nationalism; Crane is trying to state that all of these emotions we associate with most wars are really made up so that generally people will feel better about their actions in the long term. Crane questions whether or not war is ever really worth anything to anybody in this poem. Crane clearly does not think so, considering the level of sarcasm he uses throughout the poem, especially at the end when he powerfully states Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind. This is very powerful, and Crane very clearly points out that the glory of war and honor of battle are not worth much to a parent whose son has died, or wife whose husband has died, or child whose father has died. Crane's questioning of warfare is very relevant in today's war when we are as a country in what many people would call a meaningless war.
Q:what batteries fit in the JG 614 crane stock version can i have links to buy i do not like airsoft megastore?
Crane okorder.com/ I don't really like the crane stock batteries only because they are a mess to put into the gun and taking them out is only a bit better. If you're not a spray-and-prayer, a small nunchuck/butterfly battery would do just fine.
Q:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane,?
Fast Crane = A unload x /hour Slow Crane = B unload y /hour A + B = 8 hours x /hour + y /hour = 8 hours (average rate) average rate = (x + y) / 2 so 8 hours = (x + y) / 2 and x + y = 16 since the slow crane is 12 hours longer, x must be 2 hours, since they will both take 2 hours and the slower crane will take 2 hours plus 12 hours equalling 14 hours. The rate of crane A is 2 hours to unload and the rate of crane B is 14 hours to unload. The average rate for both to unload is 8 hours. There were certain assumptions made to solve this puzzle and it is not clear how they actually operate on the ship while unloading. ~~ The most practical way to unload the ship is *NOT* to use the slower crane since it takes longer for them to work combined, than for the faster crane to work alone !! A tricky but fun question !! :-b
Q:paper cranes?
Most people give paper cranes to their love ones who are ill. Since it is a tedious job, they will all help each other in folding it. Shalbi I may be wrong, but I know that to be able to make a wish, you have to fold the cranes yourself. The wish can be anything, but the most common wish is to recover from sickness and have a prosperous life. A crane signifies longevity and fidelity that is why they like to use them on weddings. ^_^

Q:How do the cranes used to build tall buildings get put in place?
They are self-elevating. They jack themselves up. It was the invention of the self-elevating crane and the self service elevator which made popular tall buildings. In older cities, such as Paris, the height of a building was limits by the number of flights of stairs people were willing to climb.
