Q:what is the common cause of crane accidents: Overloading,crane outriggers not properly deployed or on soft ground, gust of wind causing load to sway out of control, operating too close to power lines, worn cables, mechanical failure.

Q:If so, would you mind finding me a site that will teach me how to either with a good video or an easy-to-follow explanation because i tried many sites and i just cannot understand clearly enough. I get so far and then i can't tell what is happening in a step, and i can't do it.If you wouldn't mind to find me a site that you know will help, since you can make them, it would be greatly appreciated.Thanks.: Video okorder /

Q:The story I'm writing that has Frank Crane in it is here. Is there a better name I could be using for the protagonist?: I just read your skimmed through your story very quickly. His personality from what I got from the story seemed to fit the name Frank Crane very well. I like the name for that character. Not sure what other name options you have in mind though, maybe you should post some other naming options. BTW, cool story.

Q:Firstly, I realize that the 1000 paper crane thing is based on faith and not science. I'm not stupid. Secondly, Do the 1000 cranes have to be in the same place? If I send one of my cranes to a friend across the country, would that no longer count as part of my 1000 cranes?If a crane gets destroyed, must I start over or replace that crane?If anyone has any knowledge or link pertaining to the 1000 paper crane myth, please post it. Thank you.: The myth seems to surround the FOLDING on the 1,000 cranes - it is the sacrifice on the part of the person doing the folding that is the magic not the cranes themselves. See the Wiki......

Q:Crane lifts a 600-kg bin with an initial acceleration of 2 m/s^2. Determine the force in each of the supporting cables due to this motion.?: F = ma Assume the crate is uniformly loaded, both cables will carry the same force F(AB)(4/5) = (600/2)(9.8 + 2) F(AB)(4/5) = 3540 F(AB) = 4425 N F(BC) = 4425 N F(B-Crane) = 600(9.8 + 2) F(B-Crane) = 7080 N As a form of exchange, please remember to vote a Best Answer from among your results. This is not the same as like or thumbs up which are also nice and do boost points, but only after asker awards initial points with their vote.

Q:Can the tower crane personnel install the construction elevator?: First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same

Q:How do they get the tower cranes (the ones used to build sky scrapers) so high? It's not like they can ship them all in one piece so how do they make them taller? I've always wondered that...: Really simple to put up BUT you must double check all your pins and triple check yourself as you go up with the tower crane I have helped put over 24 tower cranes. Only have experienced men do this and always check every step as you go up.

Q:What do you think of this?A teenage boy giving a girl 1000 paper cranes to show his love for her, despite the fact that she previously said she just wanted to be friends. They are 14. He just wants to prove it to her that he is unlike any other boy.: dats so sweet .. really

Q:science project: hydraulic

Q:I know how to make cranes and I'm pretty fast at doing so but in pictures I see of crane leis the cranes look like they're folded differently so that they can be stacked on top of each other.. Can anyone teach me how to fold like that so that I can make a paper crane lei?: But I do different from step 11 on Step 11: Normally they fold along the red line. I dont. On step 10 you see the cross line in the center +. I then fold the right pointy toward the center. Do the same for all. Step 12: I the filp the right top layer to the left, same with the back side. Step 13: fold the bottom point to the top(one layer only) filp to back side, do the same. Step 14: flip right layer to the left again, same with the back side. Step 15: Pull and done.
