Q:Why is it that when you see a deer dead on the side of the road its neck is craned back ?
i think it does that because it is very scared
Q:Breifly explain the brake system in the lifting devices ex. Over head crane?
Cranes work using hydraulics and cables. The cables are wrapped around pulleys and the pulley is turned using hydraulic power. The brake system is simply stopping the pulley from turning by reducing power. The hydraulic system typically will turn a series of gears which in turn spins the pulley that the cable is wrapped around. It's different than a brake system say on a car where when you hit the brakes, pads squeeze on the interior of the wheel rim slowing it down. Cranes you just reduce power and stop the pulley from turning. They also have emergency stops. Older cranes have wedges that would be released onto the cable and then the wedges would grab the cable and slip into a ring. The narrow end of the wedges would slip into the ring first and then as the wedges increased in diameter the grip on the cable would get tighter and then stop the cable from moving. They also have systems on the pulleys to stop the pulley from spinning. They essentially work the same way as a car break. When the emergency brake is triggered, pads will squeeze on the rim of the pulley to stop it. These mechanisms work by friction. They could also have holes around the pulley and a steel pin would be pushed into one of the holes to stop it from spinning. Of course if the force of the weight exceeded the strength of the pin, it would shear.
Q:ichabod crane?
Maybe he drank a lot of absinthe and smoked a lot of opium!
Q:Dream about Cranes.........?
First of all, to see a crane in your dream, represents happiness, maternal love, and your gestures of good will. You look out for those who are near and dear to you. Alternatively, a crane signifies tact, immortality or vigilance. Furthermore, dreaming of an angel can mean two things. Purity, protection, comfort and consolation. Pay careful attention to the message that the angels are trying to convey. These messages serve as a guide toward greater fulfillment and happiness. Alternatively, it signifies an unusual disturbance in your soul. Angels may appear in your dream as a result of your wicked and mean-hearted activities.
Q:How do they erect a crane without the use of another crane?
Although I haven't seen it done I imagine that especially for very high cranes it's done most often with cables and winches (utilizing a pivot point at the bottom of the structure). For many lower cranes such as those found on vehicles hydraulic lifting is sufficient.
Q:why are siberian cranes endangered?
Would you spend a winter in Siberia if you could fly south?
Q:how much does a whooping crane eat per day?
To figure out exactly how much they eat you would have to know the exact weight of the bird, the calories in the food, and the condition of the bird. Which is a very long way of saying that I don't know the answer to your question, but there is a mathematical way to figure it out if you are really interested.

Q:Are tower crane operators secured by anything when they climb to the control room thing? What is the average salary for an operator?
1. No need to be secured, the ladder inside the crane tower has many platforms. It's actually a heap of ladders and platforms not a single ladder. Usually the ladder is surrounded by a cage that would catch you if you fell. Once at the top there are handrails everywhere, you just make your way to the cabin. 2. Average here in Australia is about 1500 to 2000 non union and 2500 to 3000 union. 3. Not worried climbing but if there is a thunderstorm and you are in the cabin it can be scary 4. You shouldn't climb the crane when it's rainy as its all steel it is slippery if wet but sometimes it cannot be helped. You should wear non slip boots too
Q:Is the Stephen Crane Short Story The Bride Comes To Yellow Sky a Big Fat Parody?
I have to say no. Your question erred in a significant way. Hollywood didn't create this false image of the West. The false image was created a long time before by people living in the age of the incidents. It didn't take publishers long to notice that people living back East enjoyed these gritty depictions of the West. Dime novels were a big seller in the 18th and 19th centuries. Look at Stephen Crane. He died in 1900. Hollywood was non-existent as the facet of American life that it holds now. Crane would have been writing this story with the idea that he was depicting a real slice of the wild West that was becoming more civilized.
