Q:Hi,I am looking for study for Design, Calculation and selection of Overhead Crane supporting Columns. (Not the Crane runner way beams ) Could you please suggest me the suitable references on internet?Thank You !
See okorder /
Q:A crane lifts a 2355 N bucket containing 1.81 m3 of soil (density=2084 kg/m3) to a height of 7.56 m. Calculate the work the crane performs.
Mass of soil(m) = V x d =m = 1.81 x 2084 = 3772.04 kg =Weight = m x g = 3772.04 x 9.8 = 36965.99 N Thus the total Force by crane = 36965.99 + 2355 = 39320.99 N Thus Work done (W) = F x s = 39320.99 x 7.56 = 297266.70 J = 297.27 kJ
Q:What species of crane/heron is at 3:07 of this video?
It is a stork, not a crane or heron. The painted stork, Mycteria leucocephala. The first pic in this link does not make the identification clear..

Q:My boyfriend's a little sick right now, and he's going to have a surgery over summer. I'm in the process of folding him 1000 cranes (like the Japanese legend), and in every crane I wrote a message. I have a list of all the messages so far. I'm not sure how to give it to him, though. 1000 cranes is a lot of cranes... and I don't want to make him carry a big heavy box or anything. I also want him to be able to read the messages... something I didn't think of much when I decided to write them on the paper I folded the cranes with...Anyway, I was thinking about a scrapbook or something. But that would be a really big scrapbook. And I'd have to probably write out all 1000 messages again in it... Plus, I'm not sure if I can find a scrapbook with enough pages.Any ideas?
3 Aw that is so sweet, maybe you can make a mobile or tie them all on a string. i also really like the scrapbook idea, maybe u can make the cranes small so that they all fit in the scrapbook.
Q:I have got a ton of Mosquito Hawks in my house. Should I just let them be or will the problem get worse? Plus I read they dont bite humans but will the bite rabbits? I have 2 house rabbits that I am concerned about.
So called mosquito eaters, mosquito hawks, or skeeter eaters. Unlike mosquitoes, crane flies are weak and poor fliers, so they can be caught easily and without much effort. Despite their common names, crane flies do not prey on mosquitoes, nor do they bite humans. Adult crane flies feed on nectar and consume roots such as turf grass as in backyard lawns.(So they won't be preying on your rabbits) Their life cycle is very brief, so you shouldn't have to worry about them multiplying. They are also weak and poor fliers, so they can be caught easily.
Q:I know that there's Tibetan and Fujian but what are all the styles and which is the best one to learn ( in your opinion)
tibetan, fukien, shaolin, ans emei, for starters. WING CHUN was originally a combo of crane and snake.
Q:If you make 1000 origami cranes is it true that you will get a wish or good luck. This is based on a Japanese myth
That depends on your wish. If your wish is to have 1000 origami cranes or your wish is that you become really good in folding origami cranes I would think it will come true. But maybe you could also wish for a smile from every stranger you give an origami crane to as a present, you might not even have to wait until you've made 1000.
Q:I had a dream and it wos really scary so realistic i woke up crying and could go to work the next dayi was in my house and woke up and came downstairs and there were letters on the floor and someone was picking them up then i looked outside and there wos a big fire and a crane had fallen down and explosion and everyone was dying their faces burnt i burst out crying. what does it mean?
Probably some stress or fear is looming large in your subconscious mind. Scary dreams often occur when you have something that is stressing you. That is assuming you didn't read some book or watch some movie that brought it on, that is another possibility. Often we replay images we have in our heads from the day before. I don't think it is an omen or anything. So, be glad to say it was only a dream.
Q:How are those really tall construction cranes assembled ???
its a truss... they take each piece and attach it... its no hard
