- Q:Hi, I'd like to know what a crane symbolises in the asian(?) culture. any other meaningful symbols do list.
- The cranes' beauty and their spectacular mating dances have made them highly symbolic birds in many cultures with records dating back to ancient times. Crane mythology is widely spread and can be found in areas such as the Aegean, South Arabia, China, Korea, Japan and in the Native American cultures of North America. In northern Hokkaidō, the women of the Ainu people, whose culture is more Siberian than Japanese, performed a crane dance that was captured in 1908 in a photograph by Arnold Genthe. In Korea, a crane dance has been performed in the courtyard of the Tongdosa Temple since the Silla Dynasty (646 CE). In Mecca, in pre-Islamic South Arabia, the goddesses Allat, Uzza, and Manah, who were believed to be daughters of and intercessors with Allah, were called the three exalted cranes (gharaniq, an obscure word on which 'crane' is the usual gloss). See The Satanic Verses for the best-known story regarding these three goddesses. The Greek for crane is Γερανο? (Geranos), which gives us the Cranesbill, or hardy geranium. The crane was a bird of omen. In the tale of Ibycus and the cranes, a thief attacked Ibycus (a poet of the 6th century BCE) and left him for dead. Ibycus called to a flock of passing cranes, who followed the murderer to a theater and hovered over him until, stricken with guilt, he confessed to the crime. Pliny the Elder wrote that cranes would appoint one of their number to stand guard while they slept. The sentry would hold a stone in its claw, so that if it fell asleep it would drop the stone and waken.
- Q:Is the crane a metaphor for the woman? Or does it transform into one? OR does the guy marry a bird? I've been listening to this all week and cannot discern which is right...maybe that was Colin's intention? A little help here?
- It's a story about a peasant living in, I assume, rural Japan, it being a Japanese folk tale. He finds a wounded crane on the road as he's walking one night. It has an arrow in its wing, and he pulls out the arrow and revives the crane. A couple of days later this mysterious woman shows up at his door and he brings her in. Eventually, they fall in love and are married. Although they're poor-- she's a seamstress, a weaver-- she suggests that she can make this cloth that he could sell and make money. But the one condition is that when she's weaving he can't look into the room at her weaving. This goes on for awhile, until eventually the peasant's curiosity gets the best of him and he looks in. It turns out that the woman is a crane, and she's pulling feathers from her wings and putting them into the cloth, which is what makes it so beautiful and soft. Apparently, having looked in at her breaks the spell and she turns permanently back into a crane and flies away.
- Q:What is the standard weight of a tower crane for 1.6*1.6*3 and 1.6*1.6*5m? Kg?
- The standard weight of tower cranes for 1.6*1.6*3 and 1.6*1.6*5m is 500KG
- Q:a crane lifts load of 500kg mass to a distance f 20m in 10s at a constant velocity. how much work is done?
- a lot
- Q:Can someone tell me the difference betweem safe working load and capacity of a crane?If possible, please provide reference along with tour answer.thanks for the help!!!
- Example: Suppose a crane is rated for a safe working load of 10,000 pounds. To verify that it can safely handle that load it will be tested by lifting a much heavier proof load. So its capacity must be greater than its safe working load.
- Q:how do you make an electromagnet crane?
- For okorder /
- Q:What is W_safe, the largest weight of the load that is safe to lift regardless of the angle of the crane's arm?
- (Wc)/(2b) for my problem.
- Q:I just watched hunger games, and in the end Secana Crane was locked in a room with nightlocks, but why did they do that to him? what did he do to get killed?
- The Capitol is a government that rules through absolute control. They're keeping the different areas under control through force, and everybody is too afraid of being killed to stand up to them. The Hunger Games are there to make people afraid of revolting and to give them some hope of one day becoming famous. Crane got killed because he allowed Katniss and Peeta to beat the game. The point of the Hunger Games is that there can only be one victor, but Katniss let them both live. By doing that, she showed that the Capitol couldn't control everyone absolutely, and they could beat the Capitol if they tried. Crane got killed because he let that happen. It also drives home to the reader how brutal Snow can be, and how willing to throw away a life he is.
- Q:How were Churches and really tall buildings constructed hundreds of years ago before the invention of cranes?
- Scaffolding, Pulley systems and lots of muscle and sweat.
- Q:An Episode Of War by Stephen Crane
- Crane saturates his writing with similes and metaphors.
