Q:On an offshore oil rig, is the crane the same as the flare boom?
The flare boom is just that, a stationary boom that supports the flare line. It is not a crane, those are completely separate and usually on the side of the platform away from the flare boom. The flare has to be set out from the platform so the radiant heat from the flame doesn't harm the people on board or the equipment. Yes there is normally a standing pilot and there will be a flame if there is a need to burn off the natural gas during an upset or emergency.
Q:How do they get the construction cranes up the sides of buildings as they increase the height of the building?
Sometimes the structure of the crane is built onto using the crane itself, building itself into a box. Then the crane lifts itself to the higher level. This can be done many times.
Q:how to say no to my child who wants to keep a pet? crane fly.?
Hi!! wong-say Why say no? Just put on in a jar and tell the little chap that they have to stay out side in the fresh air. then it will fly away and the matter is over plus the lad has learned that it is impossible. everyone is happy then.
Q:where can I find the sketch of an automotive crane?
I'm not sure what you mean by an automotive crane: a tow truck, a crane for lifting car engines, or a crane for lifting cars. Anyway, try google images. Search for automotive crane and see what it turns up.
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:Can the tower crane personnel install the construction elevator?
First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same
Q:I am going to make 1000 paper cranes?
I'm okorder.com)
Q:What is the power of a tower crane? Five
TC7525-16D switchboard power 80KWTC5610-4 switchboard power 34KW.TC6015A-10E switchboard power 71.5KWThe other two types have not been touched and will not be answered. I'm sorry
Q:How to do a simple Fujian White Crane block?
There is no simple crane block. This is a myth perpetrated by some of the Hakusturu people. I study Fukien White Crane and I gave you a reference in the question you asked before. Just like there is no crane stance. There are many blocks and stances in White Crane boxing and they are ALL crane blocks and crane stances. The blocking system is very sophisticated and takes hard work and proper mechanics to grasp the idea. Do you have a Fujian White Crane school near you? If you do, enroll in it and learn it the right way - under a trained instructor. I guarantee you that you will not be learning any blocking applications. In the White Crane Arts, you do nothing but Sam Chien for the first three years. So forget this fantasy of learning it here on Yahoo Answers. Edit: Let me correct myself - there are not even any blocks in White Crane Fist. All the movements you see are trapping and grappling techniques. It is an Internal Art so the idea is to trap the opponent and destroy the attack using explosive energy.
Q:what does the expression, fate is a ninny woman, mean. from open boat by stephen crane?
Well, it means Crane was sexist, for one thing. :o) I think it means that he thought that fate could be fickle, capricious, and not appear to be very smart compared to how we would like things to turn out.
