Q:live in marshes???

Why didn't you just wiki it? The common name of this bird references habitat like at the Platte River, on the edge of Nebraska's Sandhills in the American midwest.

Q:When making 1000 origami cranes, do all of them have to be the same size? I already made some of varying sizes. Does it matter? I hope not.Thank you.

I don't believe there are any size restrictions, the main requirement is that there be 1000 of them. Since a lot of origami paper is prohibitively expensive to buy in large amounts, you'll probably be better off folding with whatever is convenient to you. This also frees you up to fold wherever and whenever you like, without having to lug around a certain size paper or a ruler and scissors. For instance, Sadako Sasaki, the famous Japanese school girl who attempted to fold 1000 cranes before her death from raditation-induced leukemia, had to fold with whatever paper was close to her - spare bits of medicine wrappings, napkins, candy wrappers, and wrapping paper from get-well presents.

Q:How much height should tower crane work at M?

When the crane in the layout to drawing, especially in real estate development area, residential buildings, such as tower crane, but also to consider the safety distance of adjacent tower crane, two in horizontal and vertical direction to ensure the safe distance of not less than 2m, the adjacent tower crane tower crane and interference can not occur.

Q:I have seen a crane sitting in a tree watching over the pond in my front yard. I have never seen any fish in the pond and so i am curious as to why the crane is there. I thought cranes only hangout by ponds if there are fish. Does anyone have an research hypotheses to why the crane is there?thanks in advance

maybe it's nesting? it's migration season so it might just be a stop-over. where are you? we saw sandhills go over a few weeks ago over oak park IL about a month ago.

Q:explain thoroughly please

Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left). If you find this helpful, please award Best Answer!

Q:if i make 1000 origami cranes what does that mean?doesnt it mean that you get a wish or something? cause i heard a story about it a long time ago but i dont remember. im pretty sure that if you make 1000 cranes you get one wish

I don't get it. Who's going to grant you a wish? The magic crane genie? Buddha? Why not try praying to God who might be able to help you, without going to all of the work and giving yourself paper cuts.
