Q: Where you stand on one leg with your hands up and out to sides.Isn't standing on one leg in a fight leaving you exposed and vulnerable? What techniques can you actually do from that stance anyway (other than jumping up and kicking with the leg that was on the ground like the karate kid).: Kung Fu Crane Stance

Q: What other actress of the 1960s who could have done the role of Marion Crane in Psycho,in place of Janet Leigh and give result too?I think she perfect.: Eva Marie Saint might have but Kim Novak I think might be a stronger choice than Saint. There really weren't any other major stars that fit Hitch's 'look' of the girl. And this one needed to be strong and independent.

Q: Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?: After this the crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on an approximately 40 foot mast that consists of two mast sections. The mobile crane then adds the counter weights. The mast which is a large triangulated lattice structure typically 10 feet square then rises from this firm foundation. This triangulated structure gives the mast the strength to remain upright. The tower crane rises to its maximum height by using one mast section at a time, the crew uses a top climber that fits between the slewing unit and the top of the mast. This is done by hanging a weight on the jib to balance the counter weight. The crew then detaches the slewing unit from the top of the mast, this is done by using large hydraulic rams in the top climber to push the slewing unit up to 20 feet. The crane is then used to lift another 20 foot mast section into the gap opened by the climbing frame. Once bolted in place the crane gains a height of 20 feet. This process is reversed once the building is finished and its time to dismantle the crane and as stated earlier a smaller crane is used to dismantle the tower crane except the mast which is dismantled by the crane itself

Q: How were Churches and really tall buildings constructed hundreds of years ago before the invention of cranes?: Scaffolding, Pulley systems and lots of muscle and sweat.

Q: Okay, well obviously, in The Legend of Sleepy Hollow,he was ugly, but wat exactly made him ugly?? it tells you, but its way too complicated for me. Could anybody just make it... simpler?: His okorder /

Q: A crane lifts a 2355 N bucket containing 1.81 m3 of soil (density=2084 kg/m3) to a height of 7.56 m. Calculate the work the crane performs.: Mass of soil(m) = V x d =m = 1.81 x 2084 = 3772.04 kg =Weight = m x g = 3772.04 x 9.8 = 36965.99 N Thus the total Force by crane = 36965.99 + 2355 = 39320.99 N Thus Work done (W) = F x s = 39320.99 x 7.56 = 297266.70 J = 297.27 kJ

Q: Today, my boyfriend surprised me with an origami bird he'd made for me the night before, just for no reason. He told me he'd tried to make a crane but it got to be to complicated. I thought an was an incredibly sweet gesture, and I thanked him thoroughly. I was wondering if it would be nice to give him an origami something back? I found a really easy video on how to make cranes and I made one, but I don't want it to seem like I'm trying to show him up, I just want to show my gratitude. Would it be best to give him the crane, give him a different origami animal, or just let the whole thing go? Sorry if it seems like I'm over thinking this, I just really like him :): NOT the crane, another origami animal perhaps or give him something different. The crane will so seem as if you're trying to show you're better :P so sweet he gave you a bird though! Be happy! :D

Q: I need to know exactly how much weight they can lift also how much do they weight?how long is thier life-time?in what temprature they can work?does mosture do any harm to them?for installation , do they need foundation?the exact height and width?: You need to be more specific. The lifting capacities for container cranes varies significantly, as does any other crane. Some of the variation is based purely on load (horsepower) availability; some is based on speed (rpm) for lift/drop portions of the cycle. Cranes like these operate year-round, at ports all over the world. Some ports have average ambient temperatures in the range of 45 C, with highs up to 60 C. Others can be as low an average as 10 C, with a low peak as much as -50 C. Moisture will, over the long haul, harm them - they're metal constructs, and thus are prone to oxidation. Using corrosion-resistant materials and/or coatings will certainly prolong their usable lifespan. The crane drives (electric motors and power electronics) are also susceptible to moisture and other contaminants. All true dockside cranes require some sort of permanent foundation; it's usually part of the pier construction itself. However, there are portable cranes that operate without one. There is also more than one crane manufacturer out there - all will have their trade secrets that will make each look a little different than the rest. It will generally also reflect in their operation parameters, and in their expected life cycle.

Q: What do the words neck-craning and neck-straining mean in the sentence below?Sports cars are often designed to make a statement, and many of the newest models do that with neck-craning styling and neck-straining performance.: 'Neck-craning' in this context I think means to crane your neck around to see all angles of the presumably beautiful styling. Neck-Straining in this context I imagine refers to the G-Force experienced from acceleration provided by the high-performance sports-car.
