Q: the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
difficult question
Q: i have to make a children's story about how the whooping crane became endangered; (based on real facts) ideas?
Check out these books: The Whooping Crane by Alison Imbraico The Birds of Heaven by Peter Mathiessen Cranes by Janice Maryan Hughes The library should have some childrens books for you to look at. Hope this helps.
Q: Hi guys, I am doing a project for school on blue cranes, and i can't find much on what their diet is like? Does anyone know?
Blue cranes are omnivorous and eat plant, grain and insect material. I may not listen to my science teacher, but at least I know this.
Q: How do they get the tower cranes (the ones used to build sky scrapers) so high? It's not like they can ship them all in one piece so how do they make them taller? I've always wondered that...
Really simple to put up BUT you must double check all your pins and triple check yourself as you go up with the tower crane I have helped put over 24 tower cranes. Only have experienced men do this and always check every step as you go up.
Q: list of people confirmed dead from crane accident nyc?
i imagine they are injuries. regrettably those who artwork for the city authorities - a minimum of in lengthy island - are extremely incompetent and corrupt. What makes you say that No inspector ought to deliberately ignore a risky contemporary challenge ? That 's precisely what the inspector of the first crane crumple did. Oops, my mistake. He did not verify the cranes in any respect. And all those those who died lately in structure by utilising being blown off by utilising wind from large heights??!! I have in no way heard something like that in the previous. Who supplies those people the needed facilitates?? How educated are those people? the position is their union?

Q: How did Romans make columns in roman times Without cranes?
Columns weren't one piece - they were stacked. They had cranes of a type the used human lifting power.
Q: My understanding is that under Crane doctrine the tax basis of the property to begin with is Equity Invested + Financing (recourse or nonrecourse doesn't matter). i.e. 20K down + 80K purchase money mortgage = 100K. What if the property is appraised for only 80K right before purchase but purchaser paid 100K? Is the tax basis 80K or 100K.In other words, is the tax basis the actual assessed value of the property or is the tax basis the total investment?Thanks,Ben
Your understanding of Crane is correct. For purposes of calculating the gain on sale, the basis would be $100k. What Crane really said was that the net proceeds would have to include any assumed debt, in addition to any cash received -- basically that you had to include the debt on both ends of the transaction if my reading is correct. (That jives with the example in Commissioner v Tufts et al, 81-1356 so I think we're correct on that.) Where basis gets interesting is when you are calculating depreciation. At least when you convert a residential property to business use -- i.e. a rental -- you use the LESSER of the cost basis (Crane) or the FMV on the date that the property is placed in business(rental) service. In your example, the depreciable basis would be $80k since that was the lower. For calculating the gain on sale, the cost basis would still be $100k (adjusted down for any depreciation allowed or allowable while in business use of course).
Q: im really curious about the 1000 paper crane legend. i went on many different websites to learn about it. one said that you are supposed to have 25 strings to hold the paper cranes (40 each) on it and is that true? also a lot websites said that they used them for weddings so do you have to use them for weddings? or can it be any wish you want? i have a few more questions about it but i will ask whoever seems to know the most about it. thank you:)
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: Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?
Use trigonometry, it's a triangle of forces.
