Q:Why does Crane deliberately place the dinghy's crew in sight of land in the story?
The Open Boat is a true story - Crane was sent to Cuba as a war correspondent in 1897, and he boarded a vessel named the Commodore. The vessel sank off New Smyrna Beach, Florida in heavy weather, and the survivors made their way to shore in the open boat described. The wreck of the Commodore is in 90 feet of water, fourteen miles out and is currently under an Admiralty salvage claim.
Q:On the wing chun T-shirts they got i print of a crane and a snake what do they mean and the yin and yang?
Wing Chun was developed from the five Shaolin animal styles, tiger, snake, crane, panther and monkey. The popular (incorrect) belief is that the style contains more of the crane and snake styles than of the other animal styles, hence why it is sometimes referred to as a crane and snake style. The crane, in the Shaolin system, is evasive, protective and gentle, using flowing techniques that redirect the attacker's energy, rather than fighting strength with strength. The snake is a very fast, straightforward style, protecting the centreline and attacking along straight lines with quick thrusting finger attacks. These two principals are, admittedly, very prominent in Wing Chun's use of the centre and central lines, the use of chisao (feeling) in techniques, and the use of straight, stretching techniques like the finger-strikes. (The bit that some people don't realise is that Wing Chun contains elements of all 5 styles, including tiger, panther and monkey, as well as some elements from non-Shaolin styles, such as elements of tai chi, shuai jiao (Chinese wrestling), dim mak (pressure point striking), chin na (joint manipulation) and others.) The yin-yang symbol comes from Taoism, and represents the equality of opposites, such as night and day, sun and moon, hard and gentle, forward and backward. Wing Chun, and indeed all Chinese martial arts, contain Taoist philosophies and strategies that can be explained by the use of this symbol.
Q:What is the secret to the animal crane?
It depends which type of animal crane you are talking about. If it's the jumbo cranes that pick up the huge stuffed animals, they are actually set to give out a win every so many plays, however the number of the winning play varies based on the location. If you are talking about the average sized cranes, the key is to look for a stuffed animal that is light up on top and bottom heavy. This will allow you to grab ahold of the head or neck and pick the animal up. I've found the easiest cranes to win on are the ones that you pick up beanie baby sized stuffed toys. They seem to win, every time you aim the crane to pick up the head or neck. It's a great way to rack up a lot of stuffed animals. While they may not be huge prizes they are reasonable ones, and some of them are pretty cute.

Q:What is the insulation resistance of tower crane?

Q:If a crane fly loses a leg...?
Chances are, it won't be O.K. Some spiders can release their legs, but only if given fair warning (a gentle tug). If the crane fly lost his leg violently, he will probably die from the injury. Whether or not the injury kills him, he will, of course, be more vulnerable to predators. Not to be morbid or cold, because I really do love animals, and hate to see harm come even to the under appreciated invertebrates, but the Crane fly usually only lives a couple of days, so as long as he mated, his job on earth was finished anyway.
Q:Is Air Crane a Trademark-able name for a Rigid Airship used primarily for moving heavy objects from above?
It's okorder.com/.... Judging by the fact that a Google search results in many different companies/aircraft that incorporate the term 'air crane', I would say so. But it seems that the term is usually associated with heavy-lift rotorcraft. It also appears that the term is in the public domain. So, you could call it 'JV's Air Crane' or something like that. I've Googled SkyLift, AirLift, Zeplift- all taken However, DiriLift, DirigiLift,and ZepCrane yielded no results. *I relinquish all rights to these terms
