Q: Tower crane railing height is greater than or equal to meters
GB 6067 requires the height of the railings of the crane to be 1050mm, and a horizontal bar with a spacing of 350mm shall be provided. The bottom should be set at a height of not less than 70mm.
Q: What time period would you consider that Stephen Crane wrote in? I have no idea. By time period, I mean like the kind of writing from those times. Ex: Renaissance Period.
Crane was from the late Victorian era, timewise. His prose writing was American realism or naturalism, but his poetry was more modernistic. The Edwardian era began just after his death in 1900. Although his most famous work was The Red Badge of Courage, he was not even born during the Civil War.
Q: It is my contention that God could be held accountable, at least as an accessory, for any crime. God had knowledge of these events in advance and did nothing.
Denny Crane of course, it takes one god to defend another. (blasphemy FTW)
Q: so yeah i know that cranes do the main work but i guess there are no such really toll cranes to do that with skyscrapers ?
They put a crane on the ground, and they build 5 stories, say. Then they put the crane on top of the 5th story, and build another 5 stories, then they put it on the 10th story and build 5 more, etc. Or it's hanging on the side of the building, moving upwards as the building rises.
Q: You see cranes on the floor which rise about 50 metres, but sometimes, when building high sky scrapers, I see cranes on the 70th floor or the 80th floor. How do they put the the crane so high up there when it can only go up high around 60-70 metres?
these cranes are self raising. as they need to go higher they raise themselves up on hydraulic jacks and another section is bolted in the gap that is left. i hope this will answer your question
Q: I've been watching Passions for years and I don't understand what in the world is going on between Fancy and Pretty Crane... what did Pretty do to her??
i really want to know but they have not said yet. and i am a daily passions watcher :] record it every day !
Q: Because they look a lot alike. Such as if you reinforced the design a little bit will it work?
It might - but the center of gravity and the tripod might not be able to hold the weight of the jib, camera, counter-weights... and personally, I think it would be a pretty expensive mistake to watch my $2,000 camcorder fall and brake because the camera crane collapsed under the weight. A mic tripod is designed to handle about a pound of weight. A consumer camcorder, the jib and counterweights (and maybe a mic or whatever else you throw on there) can be between 5 pounds and 50 pounds. That's why companies like Kessler make what they make. And that's why the companies that makes lesser camera cranes (Cobra, CameraCranes, and others) never use a mic tripod. They use a heavy duty camera tripod or other LARGE, STRONG, item - not a mic stand.
Q: My science teacher wants to know why cranes make work easier rather than just lifting an object yourself. She refers to the formula of force x distance. So i have to compare (in a way) the work of a human lifting an object and a crane lifting an object. Grrrr.... I hate this project!
The type of crane she is referring to ia a simple pole with a fulcrum placed between the person operating the crane, and the mass to be lifted. Imagine a weightless pole with a rope tied to one end attached to a mass of weight 224 lbs The pole is 9 feet long Let's say the human weighs 112 lbs, or half of what is to be lifted. Without a crane, it will be difficult to lift that much and swing it around. With the crane, though, let's look at the advantage when a fulcrum is placed under the pole and the person pushes down on the pole to lift the weight. First, note that gravity is in favor of the person to use their weight on the pole. Using physics, with the fulcrum place at x from the mass to be lifted, the downward force of the person is F*(9-x)=224*x or F=224*x/(9-x) now plug in some values for x and compute the force: x F 4.5 224 3.5 143 2.5 86 1.5 45 0.5 13 I started by placing the fulcrum exactly in the middle and then moving the fulcrum in increments of 1 foot closer to the weight to be lifted Notice that the more pole towards the person pressing down, the less force the person has to apply to lift the weight. Also, note that when the fulcrum is in the middle, the person must apply a downward force equal to the weight - which willl be difficult foir a person that weighs 112lbs. However, once the fulcrum is placed 2.5 ft from the weight, the person only need apply 86 lbs of downward pressure. Leverage. j
Q: I'm 17 and I was planning on reading it for class, do you think it will be easy to read?
Stephen Crane, Maggie is fantastic! I read it in school when I was 14 so I have no doubt you will have no problems in reading it. Maggie is the tale of an inevitable fall from grace on the part of a young, innocent girl trapped in the vicious world of New York City's slums. Yearning for acceptance and love, beaten at home by alcoholic parents, Maggie sets out with Pete, a local bartender whose cultured mannerisms elicit great respect from the impressionable young girl. However, when Pete spurns her for another, Maggie is ejected out onto the street, forced into prostitution to make a living. We last see her moving off, a huge, oily fat man in tow, for a darkened corner in the city's seedy underworld. If Upton Sinclair's The Jungle is a torrent of social anger and protest, Crane's Maggie is like a brilliant lightning strike, flashing across our vision and leaving us temporarily blinded. The book--scarcely 70 pages--is succint, brutish, and merciless. Crane allows his readers to form their own opinions regarding the characters. His innovative use of near-phonetic spelling to depict in the reader's ear the local dialect of New York's rough neighborhoods was shocking and difficult to comprehend when the book was first released. It lends Maggie an air of earthy legitimacy. Ultimately, Maggie is a cry for the plight of poor children--the souls we overlook with a callous unease mirrored in Pete's offhand, uncaring rejection of young Maggie's genuine love and affection. It is, without qualification, Stephen Crane's greatest and most moving achievement.
