Q:My science teacher wants to know why cranes make work easier rather than just lifting an object yourself. She refers to the formula of force x distance. So i have to compare (in a way) the work of a human lifting an object and a crane lifting an object. Grrrr.... I hate this project!: The type of crane she is referring to ia a simple pole with a fulcrum placed between the person operating the crane, and the mass to be lifted. Imagine a weightless pole with a rope tied to one end attached to a mass of weight 224 lbs The pole is 9 feet long Let's say the human weighs 112 lbs, or half of what is to be lifted. Without a crane, it will be difficult to lift that much and swing it around. With the crane, though, let's look at the advantage when a fulcrum is placed under the pole and the person pushes down on the pole to lift the weight. First, note that gravity is in favor of the person to use their weight on the pole. Using physics, with the fulcrum place at x from the mass to be lifted, the downward force of the person is F*(9-x)=224*x or F=224*x/(9-x) now plug in some values for x and compute the force: x F 4.5 224 3.5 143 2.5 86 1.5 45 0.5 13 I started by placing the fulcrum exactly in the middle and then moving the fulcrum in increments of 1 foot closer to the weight to be lifted Notice that the more pole towards the person pressing down, the less force the person has to apply to lift the weight. Also, note that when the fulcrum is in the middle, the person must apply a downward force equal to the weight - which willl be difficult foir a person that weighs 112lbs. However, once the fulcrum is placed 2.5 ft from the weight, the person only need apply 86 lbs of downward pressure. Leverage. j

Q:What are the parts of a tower crane? What are their main functions?: Jacking frame: placing slewing mechanism, when lifting tower top, bearing the weight of tower crane balance arm, main arm and tower cap.Standard section: support the weight of tower crane itself and lift the weight of heavy load, and resist the overturning moment of tower crane.Institutions include the followingLifting mechanism: lifting heavy objects.Luffing mechanism: lifting the car to change the rotation center distance.: the upper part of the slewing mechanism of tower crane (including the main arm and balance arm and tower cap) around the rotation center of rotation.Lifting mechanism: tower crane lifting, the upper part of the tower crane elevated hydraulic power system.Walking mechanism: the crane can walk on the track.OtherDrivers’ RoomElectric boxLinkage tableA foundation bearing platform or trackOther safety devices

Q:Tower cranes, TC7525-16D, TC5610, TC6015A-10E, ZJ5910, D800-42, the power of these models is how much ah?I hope you can help me. I'm in a hurry!! Thank you！: 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:Something confuses me in dragon ball:When roshi has a flash back, he says crane didn't turn evil until after mutaito fails to kill piccolo, but in the filer where goku goes back in time, crane is an asshole before picolo and roshi referred to him as a friend before the piccolo incident.Also, why in the piccolo flash back are roshi and crane bald but in the filler do they have hair and glasses?Also, why in the filler does crane have a different outfit in the filler than the other students but in the piccolo flash back he has the same outfit as roshi?: The idea is that Crane Hermit is a selfish man that would do anything to get what he wants. In the past, Master Mutaito was there to ram some discipline in his head and have him under control. Following the events of his death and the defeat of King Piccolo, nothing could really stop him from being a selfish jerk again. Roshi probably didn't mention Crane being bad before King Piccolo's arrival because he wasn't really evil before it either. He was selfish and greedy, but not outright despicable as later... at least not that much. Roshi seeing Crane as a friend might imply that Crane had some redeeming qualities during his years as Roshi's rival under Mutaito's guidance. About their baldness, I think they shaved their heads after a while due to how monks and some martial artists tend to shave their heads. That or it's a plot hole due/filler error. It's again either a plot hole/filler error or they just switched outfits once they reached a certain level of their training, just like how you gain a different color of band as you progress in Judo and Karate.

Q:(a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?: a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.

Q:If the crane Dawkings refers to about natural selection is not operating or existing by chance, then some questions arise:1) who or what is operating the crane?2) if its self operating, how is it programmed to do so?3) who made the crane?And about designing the designer, No one did. Otherwise the crane would be lifting the operator of the crane into the crane. I guess the crane can operate by itself, but then stopped doing so when something designed the designer. Too many philosophical conundrums for me. The belief in an unified, and self-complete, creator is far less of a complex explanation than the 'crane' concept with all its requisite philosophical flamings hog's heads.: Bit by bit you may come to realise that complexity out of simplicity is much easier to comprehend than complexity from nowhere. The crane idea is from Daniel Dennet I think, and the boeing being assembled by chance is more or less what happened only bit by bit through evolution and natural selection. God is the complexity from nowhere to which I refer. Self-complete creator? did he make himself?

Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?: In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate.

Q:What company makes a good engine crane I can order online?: Dont know if you have a Harbor Freight store near you, but i bought an engine crane from them this past spring , 2 ton for $100. Go to the website and find a store by you, or maybe order one on line. good luck..........
