Q:What is the giant crane for in downtown Pittsburgh?

Q:What is a really creative way to ask a girl to prom using 1000 origami cranes?
I love the idea!!! it's really cute!!! I have the perfect idea...it just hit me! MY IDEA: Do you have a lake or some type of water flowing in your school yard? Trees too? If yes, then here's the idea: 1. Put some type of plastic wrap at the bottom of each crane so they can float on the water. 2. Hang those oragomis you've shown in trees. 3.Have one of your female friends get her and bring her to the area. 4. Then when she's wondering what's going on....here's where you come in. You said that 1,000 oragomis stand for a wish right? This is what you say with a crane out of the water in your hand: Behind these cranes, is a maker who has a wish. When you hand her the crane, she'll get the point. Hope she says yes! And if she says no, screw her! I wish the guy who asked me was that creative. Any girl should happy to have a guy go through this much just for her. Good Luck Dude!!!!!
Q:What other actress of the 1960s who could have done the role of Marion Crane in Psycho,in place of Janet Leigh?
Believe it or not? Alfred Hitchcock had thought Vera Miles would have been good in that role. He had one of his mini-crushes on Vera, and had planned to make her a superstar. However, he lost patience when Vera decided to enjoy her married life and have babies. Vera had no burning desire to become a superstar, and was happy with the work she was doing. She was also very smart in another way. She said that those parts worked out well for the blonde, sexy women that played them, but that just wasn't her look or her approach to acting. Vera Miles was in the movie Psycho, but she played the part of Marion Crane's sister. I've always thought that Janet Leigh was perfect in that role. She was so beautiful and unbelievably sexy that when she was on the screen? You couldn't stop watching her. Her ample bosom was an attention-getter all by itself. No offense to Janet Leigh, but I don't know if anyone cared if she could act or not! However, she did a fine job in Psycho.
Q:What is a safe working Area for a crane when at work and how it is calculated with different size of Cranes.?
each crane is so different. it depends on the rated crane load, the lifted distance from the crane and actuall load to be lifted. Each crane an envelope of angles to the horizontal, lifted load, and distance from the crane. The crane operator must insure that he is within this envelope or the crane may topple over. Also, the wind at the time of the lift must be considered. If you can picture a seesaw with loads pivoting about a fulcrum. When two people are on the seesaw, one person is the crane and the other is the load to be lifted. Only in the case of a crane, the fulcrum is at the crane itself with a large dead load counter weight behind the cab operator.

Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:A crane lifts a 425 kg steel beam vertically a distance of 117m?
Force=mass x (acceleration) -Gravity must be taken into account F=425 x (1.8 -(-9.8)) F=4930 w= F x deltay w= 4930 x 117 w=576810J

Q:NYC crane status post-Sandy?
My friend, that is a good question. According to the latest news conference from the Mayor, the crane's boom arm is secured to the structure. However, West 57th Street between Broadway and 7th Avenue is closed until farther noticed. In addition, the 57th Street-7th Avenue subway station on the N, R and Q Line is closed and trains are bypassing the station in both directions, according to the MTA. Good luck Native New Yorker
Q:Fujian White Crane Kung Fu?
My kind of question! I would like to start off by saying that if you have a Fujian WC school near you, you are very fortunate! I have to travel a bit and worst, wait for Sifu to be available. He is always abroad and busy when home. I learn Yong Chun White Crane. I have practiced Okinawan martial arts all my life and WC is the ancestor of my art, or rather, one of them. What school will you be joining? And Paul, what school do you train in? I also love the Hakka arts, which are somewhat related. FWC is an internal art based on Sam Chien training - Sanchin. It's great to know of others who are interested in White Crane Fist. Lets keep this conversation going!
