- Q:I need it for my English class, not to cheat, but because my literature book only has an excerpt, in which I didn't even know Yukiko's name. And my teacher insists on finding it out for ourselves and I just want to know what the story is about and what the scandal repeatedly implied in the excerpt is.
- It's been a while, but I believe the story is about a young girl who gets cancer, and sets about making 1,000 paper cranes for good luck, but she never made to completion. Just google to find info, or see if you can download the book.
- Q:i have 5 tower cranes outside my window at different construction sites and they all position their cranes the same direction at the end of the day. is there a reason for this.
- I spent a year walking to work past a tower crane that was being used for a high rise apartment building in Philadelphia. I don't recall ever seeing it parked pointing in the same direction two days in a row.
- Q:is was about making this game where this guy knows crane style
- There okorder /
- Q:the lenght of beam is 4.5mmaterial of beam is ASTM Gr60
- difficult question
- Q:For my science fair project we have to build someething using simple machines, me and my partner decided to do the crane, but we havent been able to find any place that shows intructions on how to build it. If you can please included a step by step plan, the things you will need ( whether or not they are hard to find/ and if so where i might be able to find them ), and your sourcetruely i appreciate this sooo much thankyou in advance everything counts so please make it as detailed as possible and if you know any other sites that show please include thank you sooo much :)
- you are totally just trying to avoid doing this work by yourself. anybody with two eyes can just look up crane on google and learn how it works. they are super simple just go to the library or something. or better yet go look at a real crane.
- Q:I need to go to a tower crane school inside Las Vegas, where do i go? At least inside Nevada. Not Arizona or Utah or California.
- check with the International Union of Operating Engineers. I know that in the past, they provided the training, and past the general operators certification, there is a Crane certification, and possibly also a Tower Crane endorsement.
- Q:My kid wants to pet a crane fly because it's cool but I don't want to keep it around as a pet. I'm not a fan of crane fly. How should I tell him no? Also, I'd like to explain to him besides the fact that it disgusts me: I don't like insects.
- Maybe you can explain why dont you like crane fly, and telling your kid that it is not a pet, it is just insect.. But playing around with insects is normal for kids
- Q:how to pass a crane practical test?
- Study or cheat.
- Q:If so, what time of year?
- I have lived and worked in Lyon and have never seen a crane fly in the built up area of the city, even when they are at their most active, which is in June. There are some that fly about in gardens but in any case they are harmless even though some people are freaked out by the way they fly. It is their grubs, the Leather Jackets, which are hated by gardeners as they are detrimental to lawns.
- Q:How are those really tall construction cranes assembled ???
- I saw one erected once - it was fascinating. They started out with a big mobile crane - then they added piece by piece until they finished it.
