Q:How to interpret tea leaf symbol in terms of time of a standing bird that is a crane/egret/heron, with it s beak body facing to the right?
Cranes are an extremely ancient symbol, there are folkdances based on their courtship display in many parts of the world, and evidence of this in prehistory too. Excavations at the ancient city of Catal Hayuk in Turkey uncovered the wings of a crane which seemed to have been part of a dancer's costume (google crane dance). Herons and cranes stand around waiting patiently for fish to come along and then move swiftly
Q:Cranes everywhere in a city?
I love doing things like this! Whenever my friends go to the mall we do this. We put inspirational quotes and images everywhere we can. In the pockets of clothing, on top of the sale signs, all over the cafeteria. There isn't anything wrong with doing it, and people love it! I'm sure the cranes will be beautiful and many people will appreciate them. Be sure to write look inside on the outside of each crane if you're hiding the message on the inside! This is such a cool idea, I'd love it and I'm sure it won't even be a slight nuisance to anyone. Have fun!
Q:Which bird is larger? Mute Swan, Japanese Crane, Dalmatian Pelican, Andean Condor, or the Wandering Albatross?
Not answerable as you do not indicate in what area you are considering, weight, wingspan, height? Even in weight it is controversial. The mute swan and Andean Condor weigh in at around 30 pounds. In height it would be the Crane. And wingspan would be the Albatross.
Q:What do cranes have to do with geometry?
If your referring to cranes in construction cranes, then it might form a right triangle with the ground implying the use of trigonometry which is a part of geometry.
Q:how do you make a paper crane?
Q:What do you think of paper cranes?
dats so sweet .. really
Q:How do Crane Motors Work?
I'm not 100% familiar with this but this should be pretty close to the answer. Simple/standard crane motors work by applying power first through a rotating steel shaft into a gearbox. The gearbox allows the gearing ratio to be changed (to trade rotation speed for torque or torque for rotation speed). Another steel shaft carries the power out of the gearbox, again through rotation, to a spindle (think big thimble) around which steel cable is wrapped.
Q:An 8-hp crane lifts a 100 kg junk metal over a period of 15 seconds. To what distance was the load lifted?
1 horse power = 746 watt. So the work W done by the crane in 15 s is given by W = 8*746*15 J . So the distance, S through which the crane lifted 100 kg, presumably at constant speed is given by 100*9.81*S = 8*746*15 or S = [(8*746*15)/(100*9.81)] = 91.25 m
Q:why should we save the crested cranes?
Because man is a reasoning being he has the capability of saving things. It is in our nature. Secondly, if man's activities are the cause of the Crane's extinction - destroyed its habitat or food source, then man should help reverse this.
Q:War is Kind by Stephen Crane.?
Crane is Naturalism at its best.
