Q:So, this might seem like an odd question, but here goes.I work in an office and outside the windows there's a crane. Every day I come in from work, it has turn a little. The half-finished building that it stands next to is not being worked on and there's never anyone using the crane during the day. There's no other construction going on in the area is stands at.It's pretty high up like 6th to 7th floot and it's in a windy town. Does that matter?Why would someone turn around a crane during the night? Is it all a scheme to make me paronoid because they know I'm starring out the window most of the day?

I assume it's a tower crane, in which case it's probably because if it's locked and the wind is too strong it will collapse. However if it's free to rotate it'll simply move according to the wind direction

Q:In the Pacific NW, what will get rid of Crane Flies in my yard?

If they are indeed crane flies, they have very short lives and will be gone in a short time, and do no harm - so why bother? In any case, I do not see how dolomitic lime would help - their larvae are aquatic, not in the dirt, and the adults do not feed.

Q:I've read significance and accordance online. But i can't find a source for defiance, I used epub bud for the other two books but this book isn't on the website. Is there anyway I can read defiance by Shelly Crane online for free?

Q:Hi I was with a friend and her family and they kept referring to some birds at a lake as cranes. I know for sure that some birds there were Great Blue Herons. When I here crane I think of a bird from Asia or something. Anyway these birds were white and I thought maybe they were egrets or something, and this is in Ohio. I'm not looking to prove anyone wrong, I'd just like to find out about cranes- are there cranes in America and if so could these birds be cranes? Thanks!

Some geese, if they know they can get plenty of food, don't fly south in the winter. Also, some geese go much further north in the summer, so flying to Indiana is flying south for the winter.

Q:i have a 100 ton american crawler crane. how do i calculate the psf, for this equipment.

Not sure what you are asking exactly... Are you saying that you have a crane with a capacity of 100 tons and you want to know the pressure on the soil where the crane is positioned? In this case, you take the capacity (in pounds) plus the weight of the crane (in pounds) then divide their sum by the area of the tracks on the crane (in square feet). This will result in pounds per square foot or psf as you wrote above. These are example estimates, they may not be anywhere near the correct answer, this is simply how to do the calculation. Assumed Capacity 100 ton = 200,000 lbs. Assumed Weight 105 ton = 210,000 lbs. Assumed Area of Track = 200 square feet Note: 1 U.S. ton = 2,000 pounds = 2,000 lbs. 410,000 lbs / 200 square feet = 2,050 psf There's a start, now you just need to find out how much it actually weighs and how long and wide the tracks are to get the area of the track on the ground. I hope that answers the question you were asking.

Q:I know that the whooping crane population recovered through captive breeding but how many are left currently (right now).

There were 535 total in 2009--the population increased slightly last year but I have not seen a total for the population of 2010. Deaths can occur at any time so the number changes constantly. The Journey North site counts 281 adults in the wild western population and 106 birds in the reintroduced eastern flock. They did not give a number for the birds in captivity so I cannot give you a total. You can follow the reintroduced whooping crane population and their migration each spring and fall on the Journey North (in fall called Journey South site). They also track song birds and hummingbirds and monach butterflies.

Q:How to build a strong paper crane?

Fact: paper is relatively strong when you pull on it, but when you push on it, it easily crumples. Build your crane out of several bars. Bars that are being pushed upon by the weight need to resist the crumpling. A good way to do this is to roll a sheet of paper into a tube form to make the bars. Bars that are only being pulled on don't need to be more than a sheet of paper. A frame cranes are simple to make: www.lni.wa /wisha/rules/generalsafety/images/24_d2_a-frame.gif

Q:the question is :Two cranes can unload a ship together in 15 hours. The faster crane takes 16 hours less than the slower crane, if each were to unload the same ship alone. How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2

No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
