Q:What is the most likely reason that Crane never tells us the lieutenant's name in episode of war?
The Stephen Crane Society Stephen Crane did not have a middle name. Stephen Crane is buried in ... Would a person be more likely to receive a wound when bravely charging the enemy .... I would be most grateful if you could tell me where I could find this please? .... An Episode of War. How does the facts that the lieutenant is rationing ..
Q:Boston Legal: Denny Crane Question!?
LOVE him as Denny Crane. He makes me laugh every time!!
Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
Q:what can lead tower crane to blank out?
(1) tower crane has crack; (2)Brake block friction lining wear up to 50% ofRaw material thickness ; (3)Brake wheel surface wear reaches 5mm ~ 2mm (4)Spring has plastic deformation; (5)Lever system, air travelis more than about 10% of its rated trip
Q:The mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center?
The key here is to simplify this as much as possible The equation is really: mass 1 x length 1 + mass 2 x length 2 = mass 3 x length 3 G1 * 6 ft = (G2 * X ft) + H3 * X ft) G1 = 116 kip G2 = 29 kip H3 = 38 kip Now it is an equilibrium of torque about the point where the boom pivots: 116 kip * 6 ft = 29 kip * Xft + 38 kip * Xft solve for X feet: X feet = 10.388 ft So the crane is in equilibrium when the load is length1 + length 2 times the mass = mass of motor * length 3 (10.388 ft * 29 kip) + (10.388 ft * 38 kip) = 116 kip * 6 ft The boom forms a triangle with the hypotenuse equals 12ft + 15 ft = 27 ft. The bottom of the triangle is 10.388 ft + 10.388 ft = 20.776ft So we have two sides of the triangle and now just need to find the angle where the triangle forms with those two sides: cosine of angle = adjacent side / hypotenuse cosine of angle = 20.766 / 27 = 0.7691 and the arc cosine of that = 39.7 degrees So rounding it off, angle of crane = 40 degree
Q:Is stature of the crane a Japanese, Chinese, or Okinawan form?
Found in kata from all 3 sources okinawan japanese and chinese .GANAKAKU KATA in shotokan CHINTO in okinawan kata and in FUKIEN CRANE STYLE for chinese. GANAKAKU means crane on a rock.
Q:Why are electromagnets on junkyard cranes generally circular in shape?
the guy above me has it pretty much right. It's very easy to make a cylindrical electromagnet, the calculations for it are easy as well, compared to other shapes of coil; they also generally produce a very simple, elegant magnetic field. More complicated shapes would change the shape of the field and give weird results when you try to get things to stick to it.
Q:lifting a machine by two crane?
Not enough information. What is the load weight? What is the size? How do you plan to attach to the machine. What size is the beam cross section? Capacity of the cranes? And so on. It sounds like you might need an engineer to supervise instead of relying on Yahoo Answers for an answer to a potentially deadly if not expensive way to fail.
Q:Can paper crane symbolise your love for a girl?
In the 1940's a girl named Sadako got leukemia from the atomic bomb that was dropped on Japan and she folded 1000 paper cranes to get a wish.... It has since become an international symbol of peace and the legend that it can grant a wish if 1000 are folded is still around.
