Q: How to choose tower crane in engineering, such as arm length and lifting weight?: 1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.

Q: i am having trouble finding out 2 points that Stephen Crane makes about courage in this story. can anyone please help me? =(: The okorder /... Author Stephen Crane describes this loss of individuality as a key part of the war machine. This sense of selflessness can be a good thing – like when feeling part of the human race will make you jump under a subway to save another man, or the way you care more about your team winning the game than you do about scoring that last point yourself. But it can also be dangerous, as The Red Badge of Courage reminds us. Cogs in machines usually don’t think, and no thinking means no judgment or discretion as to whether an act is right or wrong.

Q: I recently read that adult crane flies consume nectar or do not eat at all, their only purpose is to mate. After a crane fly mates, is starvation the cause of its death, or is there something else that ends its life such as age?: Adult crane flies survive from all the fat they have, from their larval and pupal stage.When they run out of it, they eventually cannot find food, and by that time, they should die of age.It's probably both causes, if not because of predators,disease..etc

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: I know that you have to unfold the origami paper crane, but how do you find the surface area of it???????????????????????????/ please help...........: Do you remember the formula for determining area? For a flat object (like your paper) the formula is Length X Width = Area. or LW=A So unfold your paper, and measure the length and the width, and simply multiply the two numbers. The resulting number will be your area. Of course, that is the area of the unfolded paper. Your crane in it's folded form will have a much different, and harder to find, surface area value.

Q: He looked so out of his comfort zone at UFC 140. No support from either Silva or Seagal. Which brings me to another question. Why weren't those 2 by his side? Seagal or Silva are always at his side.Jones' height shouldn't be an issue. He should've at least tried to use it.: machida was getting pressured way too much the front head kick has to be set up to work you cant just throw it up

Q: A. Designated operatorsB. All construction site personnelC. InspectorsD. All of the above: Crane are extremely dangerous and complicated machinery , the operators need intensive education and training , they have to pass the required tests to be certified . Now even the signal guy on the ground who helps the crane operator needs to be certified . So your answer is A.

Q: if i make 1000 origami cranes what does that mean?doesnt it mean that you get a wish or something? cause i heard a story about it a long time ago but i dont remember. im pretty sure that if you make 1000 cranes you get one wish: yea the story you heard or read was probably sunako and the thousand cranes (we read it for grade 6) it's a story about a girl who has effects after the hiroshima attack thing and shes hspitalised then someone told her if she can fold a thousand cranes she gets one wish. so yea you get one one wish.

Q: Im looking for more information on Overhead Cranes!?: Advantages of Overhead Crane for Professionals When large materials have to be handled in the building, construction and mining industries, there are several types of equipment that would be used. One of such equipment is the overhead crane, and because of its size, it is conspicuously seen at construction or mining sites. Not only does it have a domineering figure but it is also a very versatile equipment for moving heavy materials from one point to the other. This equipment occurs in many forms and the various forms it has, makes it adaptable to many environments. There are other types of equipment that are available for lifting, but a crane is the preferred choice of many people. I got most of this information from www.hoistandwinch .uk There are several reasons people in the construction and mining industries would choose a crane over other equipment that are used for lifting. With overhead cranes, there would be absolutely no need to clear aisles before materials can be moved. Forklifts or fork trucks could have their paths blocked and a lot of time and energy would have to be diverted to clear an aisle. Obstructions that could even make you suspend important projects are irrelevant to overhead cranes because they would easily make it around them without any form of difficulty. It is therefore possible to arrange your plant floor the way you would want it to be for your business, without thinking about obstructions to the lifting and movements of materials with cranes to do all the task for you.

Q: Does a crane have a pulley?AND....Is an axe a wedge?THANX CUZ I DONT KNOW WHAT IM DOING, AND OMG IM SO GOING TO FAIL MY TEST BECAUSE IM SO DUMB.: Of course cranes have pulleys. If you know how they work it should be clear. Why else do you think there are two, or more (depending on the crane), ropes attached to their hook. Every rope added, except for the first, halves the weight of the object you want to lift. If you have two ropes and an object is 5 tones, the crane will only need the power to lift 2,5 tonnes. If it has six ropes it even only need the power to lift one tonne. And an axe is a wedge, logically. In fact, every tool with a blade is more or less a wedge. After all the wedge is the principal of a blade's function.
