Q:Crane Accidents in NYC--Do you believe they are accidents or sabotage?
I believe they are accidents. Crane collapses happen. I had the dubious distinction of helping with the investigation a crane collapse that left the crane operator in an unrecognizable state. It's awful but these things do happen. Was there negligence in some cases on the part of the crane operator? Maybe.
Q:What kind of white crane Kung fu styles are there?
Fujian White Crane is short stances, short hands and close range fighting system. The other white crane is said to be from Tibet but developed in Guang Dong, southern part of China, and Hong Kong. This style emphases on deep stances, long arm movements attacks. Both of them are great styles. Steak and Lobster. which one is the best to eat? Your pick!
Q:Which Styles of Kung Fu has Tiger, Monkey, Mantis, Snake, and Crane animals?
Monkey Vs Snake
Q:Who is the most gruesome Stefano DiMera or Alistar Crane?
The DiMera's have been around longer than the Crane's. Alistar is the more gruesome because he messes with his own family memebers whereas Stefano they do anything for their own.
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:what would you wish for if you had 1000 paper cranes?
I would wish for immortality.
Q:What does a crane symbolise?
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 Γερανος (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:Two cranes can unload a ship together in 8 hours. The faster crane takes 12 hours less than the slower crane,?
Fast Crane = A unload x /hour Slow Crane = B unload y /hour A + B = 8 hours x /hour + y /hour = 8 hours (average rate) average rate = (x + y) / 2 so 8 hours = (x + y) / 2 and x + y = 16 since the slow crane is 12 hours longer, x must be 2 hours, since they will both take 2 hours and the slower crane will take 2 hours plus 12 hours equalling 14 hours. The rate of crane A is 2 hours to unload and the rate of crane B is 14 hours to unload. The average rate for both to unload is 8 hours. There were certain assumptions made to solve this puzzle and it is not clear how they actually operate on the ship while unloading. ~~ The most practical way to unload the ship is *NOT* to use the slower crane since it takes longer for them to work combined, than for the faster crane to work alone !! A tricky but fun question !! :-b
Q:how can we minimize energy losses of a crane to reduce the impact on the environment?
No hint as to what type or size of crane, so I assume it is a large overhead traveling bridge crane inside an industrial building: Consult the manufacturer for recommendations. Change its power source to something cleaner (from diesel to propane or electric). Properly lubricate and adjust all moving parts. Turn power off when idle. Schedule heavy usage during hours of low demand of electric utility power. Replace motor with a more efficient new one. Replace entire crane with a new efficient one. Replace the large capacity one with one or more smaller units.
Q:For airsoft would you choose a PEQ box or a crane stock?
If you are looking towards a JG/Echo 1 model, choose the PEQ. The Jg's crane stocks are not compatable with any crane stock battery, however their PEQs are. Having a spare battery is important........ But, if you are not looking towards a JG, then it's up to you. Crane stocks have the balance of a battery in the rear, so your gun is not front heavy, but with PEQs you can see the wiring. If you are worried about damaging your wiring, tape it in electric tape.
