Q: MP: Do you do any origami?MP: How bored are you at the moment?MP: What do you think of this She Wolf song by Shakira?I can't really form an opinion on it.
I'd suggest Fairy Dust, but I know that can be hard to find and Glitter works just as well - so just sprinkle it with Glitter :-) MP: Not really, when I'm bored I'll maybe make a crane but other than that, no. MP: Pretty bored, I have homework but I can't really be bothered with it. So I probably won't bother. MP: All I can say is I don't like it very much. It's pretty strange. Although I have just learned that I've mistaken Shakira for somebody else for as long as I've known about her - that's quite embarrassing!
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: Well I folded 100 or so cranes from cheap origami paper (red, yellow, green and blue) before I decided that I could fold 1000 cranes a reality. My dilemma is, do I keep the 100 cranes I did and fold 900 of them to fulfill my wish? Or if I discard the 100 cranes and fold 1000, will my wish be granted on the 900th crane? The reason I want to discard the 100 cranes is because it's for my wedding and the color placement of the old cranes isn't fitting at all.Yes I'm aware it's not scientific or realistic, but it's more of faith, I'm not dumb.
Consider what you would like your 100 cranes to mean. Attach strings to your 100 cranes and then hang them in a tree etc so that the wind may carry your prayers where they need to go. Then start again to create the 1000 paper cranes you want for your wedding. PS: The making of the paper cranes involves an act of faith, not the right colour to match your wedding plans. In Japan, the crane represents peace and healing. When we consider the famous Japanese art-form of paper folding (origami) the crane comes to mind before all else. Sadako and the Thousand Paper Cranes (1977), a non-fiction children’s book written by American author Eleanor Coerr, tells the story of young Sadako Sasaki who lived in Hiroshima at the time of the atomic bombing. Sadako developed leukaemia as a consequence, and lived out the remainder of her short life in a nursing home desperately trying to create one thousand paper cranes. Supposedly, if someone could make a thousand paper cranes his/her wish would come true. Sadako wanted to live. Sadly, she only managed to fold 644 cranes. After her death, friends and family folded the remainder, and buried her with the one thousand paper birds. Today, a statue of Sadako holding an enormous golden origami crane stands in the Hiroshima Peace Park. People regularly leave paper cranes. The plaque on the statue reads “This is our cry. This is our prayer. Peace on Earth.”
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 ?
The cranes hook to the side of the building and climb the steel frame as it is being built. The crane can only reach a few stories so it has to climb each story's steel frame as it is finished.
Q: is the elevation of the upper surface of the tower crane foundation flat with the elevation of the bottom of the new building? Or lower than the trough bottom elevation? ThirtyI think this is better. Please specify which specification has the relevant regulations. Which page is it? Thank you very much!
Pouring foundation does not increase the foundation safety first
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: Basically what it says on top. Also provide maybe a video to prove it.
ok,im not sure about it but...maybe if you spred the wings far enough wait for good wind and throw it at a correct angle/thrust then it is possible otherwise it will crash
Q: If the crane Dawkings refers to about natural selection is not operating or existing by chance, then some questions arise:1) who or what is operating the crane?2) if its self operating, how is it programmed to do so?3) who made the crane?And about designing the designer, No one did. Otherwise the crane would be lifting the operator of the crane into the crane. I guess the crane can operate by itself, but then stopped doing so when something designed the designer. Too many philosophical conundrums for me. The belief in an unified, and self-complete, creator is far less of a complex explanation than the 'crane' concept with all its requisite philosophical flamings hog's heads.
Bit by bit you may come to realise that complexity out of simplicity is much easier to comprehend than complexity from nowhere. The crane idea is from Daniel Dennet I think, and the boeing being assembled by chance is more or less what happened only bit by bit through evolution and natural selection. God is the complexity from nowhere to which I refer. Self-complete creator? did he make himself?
Q: Trying to find an estimated weight for a mobiles crane with a 5 tonne capacity ?
If the crane HAS a 5-ton capacity, then to be able to estimate the weight you would need to know the length of its lifting arm at maximum extension w.r.t the C.G. of the body of the crane. So suppose we have an arm length of (say) 6 mtrs, then the max turning moment at the fulcrum (from front wheels of crane ? ) due to the Load alone = 5 x 6 = 30 You need to add the moment for the arm itself. Lets say the arm is around 1/2 ton. And its c.g. is approx 1/3 the distance from the fulcrum. Then this adds another = 1/2 * 1/3 *6 = 1 So total moment is 30 + 1 = 31 The body of the crane must be MORE than this. Suppose the C.G. of the crane is 2 meters behind the same fulcrum. Then weight of the body must be 31/ 2 = 15.5 tons. Lets say the weight is 16 tons. Then the TOTAL mobile cranes weight would be 16 (body) + 1/2 (arm) ~ 16.5 tons It all depends on the dimensions of the crane, and where the c.g. is located. If the crane has ballast added right at the back, then it's overall weight can be made less since it's c.g. would get shifted further away from the fulcrum
Q: I need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?
You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle. Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C. Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants. All true dockside cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are portable cranes that operate without one. There is also more than one crane manufacturer out there - all will have their trade secrets that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.
