Q: a crane lifts load of 500kg mass to a distance f 20m in 10s at a constant velocity. how much work is done?
work done(W) is given by the change in the potential energy(P.E). here, initial P.E = 0. final P.E = mgh = (500)(10)(20) = 100000 J =100 KJ (kilo joules) therefore work done = 100 KJ. here distance means vertical height.But if the crane takes the load parallel to the ground ,then work done will be zero.Time is given here to calculate the power of the crane given by work/time = 10 KW(kilo watts).
Q: A man said to the universe:“Sir, I exist!“However,” replied the universe,“The fact has not created in meA sense of obligation.”
Apparently Mr. Crane thinks the universe is a liar or has been deceived.
Q: is there something that i can add to my bug zapper to attract these bugs and kill them faster?
Crane flies are concidered mild turf pests in some place, but they don't bite people. They like prefer moist areas. So if you want to kill them you could get rid of small moist areas or also could try normal bug spray on them.
Q: Old used 200 t crawler crane is available for purchase. What are the guidelines/ thumb rules for assessing its cost ?
Supply vs demand Extreme examples: If the crane is no longer needed anywhere, the cost will be 0; no demand. If the crane still has a unique useable function and there is only one available, it's immediate cost will be very high; no supply. So, assuming that the cranes supply/demand is somewhere in the middle, the methodology for assessing it's cost would be to evaluate the following: * Where is it located with respect to where it is needed? (place value) * How quickly do I need it, and how quickly can I get the crane? (time value) * What alternative solutions are available? * How much do other similar cranes cost? * etc Hope this helps!
Q: Is boom truck a crane truck? Are they the same or two different kind of truck?
A 'boom' is attached to a flat-bed truck and is used to unload a heavy delivery (usually building supplies and materials) to a specific location. A 'crane' is similar except that it doesn't unload things. It is attached to a truck and is used for moving heavy objects and materials from one place on another on the same property.
Q: I know this is a longshot someone will know what I'm talking about... but I just got a flash memory of a poem where a bird with long legs (I believe cranes, but it could have been flamingos or some other bird) and kids threw stones at them and their legs just snapped.... that's all I can remember, but I remember whatever the line was describing the legs snapping really well because it was in such sharp contrast to the rest of the poem.... anyone have any clue what poem this is?
The Crane and The Crow'-Aesop's fables The farmer threw the stone at the crane and broke both his legs. The injured crane said to the crow, What has become of your God-given prophecies? Why didn't you warn me that his was going to happen?
Q: I'm making 1000 origami paper cranes. I started 2 days ago and have 135 done so far but I was wondering what do to with it after. I don't want to just make them and have them sit in my room forever.
Well if you don't want to keep them you can look up organizations that wish to use them for a project. There are a lot for Japan, one that was organized recently for the tsunami was accepting cranes for a fundraiser (every crane sent in earned a certain amount of money with the finished collection being placed in an art museum). I know some hospitals accept cranes for the children's ward, that is what my class did in elementary school we made 1000 and the hospital used them as decorations for the Christmas tree. Then there are individual projects that people start online with which they are accepting cranes to fulfill the one thousand mark for people they know who are sick etc. (relates to the story behind the 1000 paper cranes practice). As a side note if you contact the organization you find a lot of the time the shipping is prepaid you just have to drop them off at the post office. Hope this helps.
Q: I have to build a hydralic system that can pick up a paper clip . the supplies you are allowed to use are 10 straws, 5 pipe cleaners, 1 yard of masking tape. 10 note cards. 2 syringes and tubing. 5 rubber bands. 8 popsicle sticks. 2 feet of string. 1 magnet. Please help.
build a basic crane out of your materials and thread the string to the magnet hold it on with tape secure opposite end of the string to the plunger on one syringe. and fix this syringe(syringe 1) to the frame of the crane. position the plungers of both syringes at mid point, and fill both with water, and fill your tubing with water. connect the needle ends of both syringes together with the tubing. pushing the plunger on syringe 2 will cause the plunger in syringe 1 to move out. pulling the plunger on syringe 2 will cause the plunger on syringe 1 to retract and can be used to lift the paperclip.
Q: I remember it was either an anime/manga or a movie but a boy or girl makes a thousand paper cranes for someone who is dying (possible their mother). I'm pretty sure it's an anime. It's not the story about the little girl with leukemia, I know that. I also remember the little girl/boy putting them on the edge of the bed or something? It's not much to go by but if you can help me I would be eternally grateful.
In Kodomo no Jikan, Rin made paper cranes for her sick mother. Ghost in the Shell: Stand Alone Complex, and Sket Dance both had crane folding for sick persons, but they weren't mothers.
Q: These cranes always stay higher than the construction process but I have never seen how they are extended to stay above all of it. They come in two formats, free standing and those attached to the building. The possibilities that I thought of was that maybe they use another crane to lift the housing and the horisontal arm to put in more modules into the vertical part; or that they extend it by some way by putting modules in at the top or bottom and that the crane has some self-lifting mechanism to accommodate the insertion of more modules. However, I have never seen this being done, nor does the construction of these cranes point to its ability to do so. The only other possibility that I could think of was that the crane is set up at the outset to be higher than the completed height of the building, hence there is no need to extend it but this does not explain how they do it for very high buildings where the crane is attached to the building and seems to grow higher with the building.
