Q:Which war is Stephen Crane referring to in his poem War is Kind?
Crane was a war correspondent, and had reported on both the Greco-Turkish and the Spanish-American wars. I am surprised you are so sure this poem isn't about the Spanish-American war; I suspect it is about war in general - certainly including the two wars Crane had seen most copiously.
Q:A crane lifts a 2.75x10^3N bucket containing 1.20 m^3 of soil (density = 2.00 x10^3 kg/m3)to a height of 6.95m?
Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
Q:What is the inspection certificate for tower cranes?
Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
Q:Really not sure about white crane kung fu?
White Crane is a very traditional style and there are not many legit teachers, make sure you have a good qualified intructor first, maybe do a check on the internet, enter their name in google and see what comes up because if they are a legit instructor and not just learning from video tapes then you are lucky WC itself is about half internal half external art, its mostly punching, dont know how exciting it is, that will depend on your teacher
Q:Is there anything similar to the traditon where you fold 1000 origami cranes and you get a wish?
The 1000 paper cranes thing really only became popular after the 2nd world war- a girl in Japan was told she woudl have a wish granted if she did it in a lifetime. She had been a victim of hiroshima (or nagasaki, i forget), so she gave it a shot but ended up dying young from the illness before she reached her quota. The point is, if it does exist in other cultures, it'll likely only be a surface similarity, I'd imagine. I remember reading in a children's book once that every leaf you catch from a tree in the fall before it touches the ground counts as a day's good luck... but i dont know if that's an actual superstition or one made up for the story. I can't remember the name of it either...
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100

Q:Better actor......Bob Crane or Alan Alda?
Alan Alda much more versitile than Bob Crane. Alda has been nominated for more awards for a variety of acting parts. All I know that Bob Crane did was Hogan's Heroes, the neighbor on the old Donna Reed Show and porn.

Q:A crane is lifting a 500kg payload straight up at a constant speed of 0.7ms-1.?
a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v² = u² + 2as: v² = 0.7² + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
Q:Demoiselle Crane chick not walking or standing on its legs?
Your baby crane might have stepped on something, But this is nothing like malnutrition, From what ive learned the crane may have a joint dysfunction in the knee but this very common in cranes, I really think you should take an X-ray of the cranes legs because,(and the baby cranes feet will expand over time) This could get worse. This is more than likely a leg dysfunction. Hope this helps.
