- Q: How do they erect those giant cranes used for constructing tall buildings?
- They build themselves actually.... well the first part is assembled by a small crane but after that hydraulic lifts lift up the top section of the crane while the crane lifts up another mid section and places it underneath itself. cool huh?
- Q: for my homework : the question was explain how a skyscraper crane uses physics moments but no where can i find out the answer and dont want a detention ekkk x
- OK... So what has your homework actually asked you to explain? Can you post the question...? There are moment forces going through a crane, is the aim of the homework simply for you to explain what a moment force is using a specific example ? A crane can be thought of in simple terms as a cantilever, ie one supported end and one free end, the lever arm force as it is sometimes referred to in schools is actually the moment force i.e. the moment for a crane with a boom L=40m long lifting a load of P=10kN would beP*L = 10*40 = 400 kNm, this is ignoring the self weight of the boom, if the boom weighed W=1.5kN/m (thats per meter, not to be confused with kNm which is kilo newton meters) then the moment generated by the self weight would be (WL^2)/2 = (1.5*40^2)/2 = 1200kNm so the total moment would be 1600kNm, so just remember for a point load the moment is force * distance from support ( in cantilevers) hope this helps... :)
- Q: The mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center of gravity at G2. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn if the suspended load is W = 38kip . Neglect the thickness of the tracks at A and B. Determine the smallest angle of tilt θ of the boom, without causing the crane to overturn.
- 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: How do you get a crane down from a tall building once it's completed?
- You don't have to worry about that in the deep south! There are no high buildings
- Q: How to explain and classify the types of tower cranes? What do QTZ80 and Q5510 mean?
- This is only the tower crane in different periods of different naming:QTZ---- is the general saying in 80s of last century, Q means steel material (usually Q235), T is tower crane (mostly tower top type), Z indicates heightening method is self lifting,PT------ is the naming method in recent years.
- Q: In the case of tower crane operation, the operation should be stopped
- In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
- Q: for example: erection, technical data...
- Well now Slartybardfast may be tried lol but he is correct give him the points lol.
- Q: I need several quotes from Thousand Cranes by Kawabata (Don't remember first name, it starts with a Y) depicting passion.At least two.Best answer goes to whoever provides the most useful quotes, not a randomly compiled list.
- Yasunari. okorder /
- Q: i need the story cranes by hwang sun won and translated by peter h. lee and i cant find it on google. help i need the story for my essay
- EEK! I just did a search under Hwang Sun Won. It appears that Cranes is a series of short stories. Is that what you meant? If it is one particular short story called Cranes, I can't find it. I would suggest you go to your teacher/professor and ask where to obtain a copy. If you can't ask your teacher, run, do not walk! to your nearest library and throw yourself on the mercy of the librarians! Another search option for you is to look for books by Peter H. Lee, specifically the ones he has edited. He has written several anthologies. Good luck!
- Q: I have a Holden 253 and I'm looking at a hydraulic street/strip cam, and I'm wondering which brand is better out of Crow and Crane?Cheers.
- crane is they cam i like but they are both good.
