Q: I need to do a report on how cranes topple, moment (physics) and there correlation (relasionship).I am an idiot and have forgotten what moment is. so please explian that, how cranes topple and why they dont topple, and the correltion between the two!thank you: First of all, let's think of a crane like a giant see-saw, where the plank itself doesn't have any weight. Now cranes have big weights on one side of the pivot, which they can move along (I think, I may be wrong). These cause what is called a 'turning moment'. The further out from the 'pivot' they are, the greater the moment. The other consideration with a crane is it's load. Generally, this is carried a lot further out from the pivot point, on the opposite side from the weights. Now consider this. If you have a small child sitting on the end of a see-saw, you will be able to balance them with a larger person sat closer to the pivot. This is the principle on which cranes work. The moment is the force times the distance from the pivot, and it must be balanced turning each way for the see-saw/crane not to topple. This is somewhat of a simplification, but hope it helps.

Q: some people call it a crane, others say claw but the point is...where can i get one? i dont want a huge one, and i dont want a small one. A medium size one. the shops have to get them from somewhere right? oh, and i'd rather not get one from Ebay. is there a business or something? thank you!: This Site Might Help You. RE: Where can i buy a claw/crane machine that you see in pizza parlors and arcades? some people call it a crane, others say claw but the point is...where can i get one? i dont want a huge one, and i dont want a small one. A medium size one. the shops have to get them from somewhere right? oh, and i'd rather not get one from Ebay. is there a business or something? thank you!

Q: Is there an effective utility for estimating the required size of a crane? I’m an estimator for a mechanical contractor, and it seems we never allow enough money for crane rental. How can I effectively adjust my estimates?: The only effective way to estimate the size of a crane when needed is to know, without a doubt the weight of the heaviest thing that you have to lift, and allow at least a 20% margin for safety. This is standard practice in building bridges, in particular - the weight of EVERYTHING is clearly marked, or just generally known. If there are bridge segments to load on a barge, for example and the heaviest segments are 220 tons, then a 300 ton crane is used. Always err on the side of safety.

Q: I was given a CCRadio and I have no idea what it is or what it does.The guy that gave it to me says it's an Awesome DXing radio (whatever that means). The display doesn't work but other than that the radio works fine and pulls in alot of stations the previous owner said. Can anyone help me understand what a CCRadio is and what it does? Thanks to all that contribute.: C Crane Company sells shortwave receivers. You can use it to listen to shortwave broadcasts, marine weather, NIST time signals, foreign broadcasts, clandestine broadcasts.

Q: What kind of flower is the Sunset Crane?: Okay, i'm going to get every backyard gardener east of denver jumping down my throat on this one, but it's time you all wake up and know the real name of one of your favorate potted plants. only then will you beleave me when i tell you the sunset crane is a type of geranium. the true geranium. not the plant most people know as the geranium is botanically Pelargonium. that silly looking, red flowered, fuzzy leafed thing everyone loves to stick in a pot by their front door every summer back east and mistakenly call a geranium is not really a geranium. even the fancy Martha Washington geranium is not a geranium. it is the Martha Washington Pelargonium. but whats the use? unless you are a botanist everybody back east is going to say i'm just another fruit cake from california. (born and raised in wisconsin i'd like to add) okay, your sunset crane is botanically a geranium, often called by it's common name cranesbill. okay, you have the real best answer, so go ahead and pick the wrong best answer from some smuck from back east who knows best. sure i have two post graduate degrees in science, been a univ certified master gardener for over 15 years and just might know a tad bit more then the eastern fair weather, summer time gardener. but don't let that prevent you from thinking i'm nuts and choosing a better, best answer. i'm used to it. grandma is always right... until her plant dies. then they call me for the real low down.

Q: how long do i have to work as a yardhand in oilfeild to become a crane operator?: You need to get licensed or certified to operate the crane. make sure you are qualified before you start complaining about not getting more challenging work. The world needs ditch diggers to so get back to work.

Q: A crane lifts a 2355 N bucket containing 1.81 m3 of soil (density=2084 kg/m3) to a height of 7.56 m. Calculate the work the crane performs.: Mass of soil(m) = V x d =m = 1.81 x 2084 = 3772.04 kg =Weight = m x g = 3772.04 x 9.8 = 36965.99 N Thus the total Force by crane = 36965.99 + 2355 = 39320.99 N Thus Work done (W) = F x s = 39320.99 x 7.56 = 297266.70 J = 297.27 kJ

Q: How many tons are tower cranes QTZ125?: The performance parameters and technical indexes of this machine are up to or better than the national standard. The maximum working range is 65m, height is 50m independent, attached type lifting height up to 180m, the maximum working range of 65 meters, the rated lifting torque 1200kN - M.The machine parameters is advanced, reliable performance, beautiful appearance, good quality, simple and practical structure, equipped with advanced safety device, convenient maintenance, safe use, reasonable price, is the ideal construction machine for construction enterprises.

Q: It frustrates me every time I play one of those games i never win. Is there a secret? If so then what is it?: It depends which type of animal crane you are talking about. If it's the jumbo cranes that pick up the huge stuffed animals, they are actually set to give out a win every so many plays, however the number of the winning play varies based on the location. If you are talking about the average sized cranes, the key is to look for a stuffed animal that is light up on top and bottom heavy. This will allow you to grab ahold of the head or neck and pick the animal up. I've found the easiest cranes to win on are the ones that you pick up beanie baby sized stuffed toys. They seem to win, every time you aim the crane to pick up the head or neck. It's a great way to rack up a lot of stuffed animals. While they may not be huge prizes they are reasonable ones, and some of them are pretty cute.

Q: i am doing a major research paper on the other Stephen Crane and would like to know some suggestions about a name for the title of this essay it is an English 3 assignment. The book that i read is called The Red Badge of Courage. please help!: ADL ( Anti Defamation League) is an unique gadget interior the hand of a minute minority of ZIONIST jews interior the U.

No ask your self they have sided against the two writers while they uncovered the certainty of the cancerous tentacles of zionism in u.s... the two writers are actually not anti-Semitic for they did no longer convey anti-Semitic racial perspectives, to the alternative they have sided with a Semitic team properly widespread to something of the international and had u.s. First interest of their ideas.. all of us might desire to be militant to brainwashing and the defamation tries via the real enemies of u.s. , Democracy and Human rights! ----------------------------------------... respond to MR_RIEUX i'm astonished to the adequate materials(hyperlinks) adjoined to his help for the ADL , and the avalanche of element to instruct John M. Steve W. incorrect of their paper on the subject of the zionism carry interior the yank politics. i'm specific maximum folk of respondents to the question have comparable thoughts ( via ballot) : mr_rieux you the single which incorrect on your protection to the indefensible, you're instituting political prostitution and intelligence genocide, I propose you spare us the widespread venom of the zionism propaganda you're participating , you and the critics to the writers above are tainting the certainty to get a moronic immoral US president misinform his tooth and take area woth your variety in murders and destructions of civility. that's severe time to freshen up the homestead from Warmongers zionist Neocons.. Sir you're a NEOCON ZIONIST!
