Q:Why did they kill Secana Crane in the end of Hunger Games?
President Snow killed him because he allowed the games to break its rules for the first time ever by having two victors. What Katniss and Peeta did was a sign of rebellion and the Capitol relented by letting both of them live, otherwise that there would be no victor. That was not supposed to happen and President Snow had already warned him to stop any signs of rebellion prior but Crane let it happen. Someone needs to be held responsible and since Crane is the gamemaker, he has to die. This is to show that no one holds greater power than Snow over the districts and Capitol and no one should defy him. Rebellion leads to death, no matter what your role is or how you might have contributed to it.
Q:Was it Ichabod Crane or Rory Emerald who got the jeepers creepers scared out of them by a headless horseman?
ichabod crane but he also got his head cut off by the horse man so im sure it was him pluss he was the main charachter
Q:how do i fix faulty limim switch in overhead crane?
Limit switch replacement requires adjustment of the cranes travel limits. The limits are imposed by the manufacturer for the application. This service is normally factory authorized only.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:What is the allowable range of vertical deviation for tower cranes?
The specified installation, construction, demolition of tower crane safety technical regulations in JGJ196--2010: the allowable deviation of verticality Tower: in the wind under no-load, the tower axis line should be less than 4 per thousand of the bearing surfaces of the lateral vertical deviation; after the attachment, the highest attachment point following the vertical deviation should be less than 2 per thousand. According to the installation state of tower crane, the deviation range of verticality is divided into 4/1000 or 2/1000. Tower crane maximum independent installation height (maximum installation height, does not need to be attached to the wall of the instructions specified in the free end) and height (the highest point of a tower crane attached to the wall above the height, body the following provisions in the specification of tower crane slewing) the vertical deviation range was 4/1000; tower crane attachment verticality deviation below the allowable range is 2/1000.
Q:what does Stephen Crane mean by this ?
This is a very critical and harsh poem. Stephen Crane seems to have a more pessimistic outlook on life than other poems he has written, and nowhere else does that pessimistic outlook come through in his poetry than here. The pattern of the poem affixes a cynical, satirical statement after every statement of War is kind. For example, War is kind, Hoarse booming drums of the regiment, little souls who thirst for fight, these men were born to drill and die. The unexplained glory flies above them. Especially when Crane says the unexplained glory flies above them, he is making a powerful statement by questioning whether all the death and destruction is really worth it. This questioning is very important, because many wars are not really for what they seem to be for. There are exceptions of course, perhaps World War II and the fight to end the holocaust, perhaps the Civil War and the fight to end slavery, but for the most part, wars are usually conflicts between cultures over natural resources and disagreements over cultural values. The glory of war, the patriotism, the nationalism; Crane is trying to state that all of these emotions we associate with most wars are really made up so that generally people will feel better about their actions in the long term. Crane questions whether or not war is ever really worth anything to anybody in this poem. Crane clearly does not think so, considering the level of sarcasm he uses throughout the poem, especially at the end when he powerfully states Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind. This is very powerful, and Crane very clearly points out that the glory of war and honor of battle are not worth much to a parent whose son has died, or wife whose husband has died, or child whose father has died. Crane's questioning of warfare is very relevant in today's war when we are as a country in what many people would call a meaningless war.
Q:What is the point of Crane Flies?
crane flies are very large. They might also play a part in pollination I'm not sure. I've never looked at the gawky insects before edit larave are decomposers in soil adults don't feed. So then the maggots are for the recycling of decayed matter. Thats their point. my info came from my field guide that is next to my bed at all times
Q:Are electric bug zappers effective for killing crane flies?
I'm sure they are, but keep it away from your house or you're going to be attracting more bugs and have them dead near your house.
Q:How do you calculate ground bearing pressure for cranes?
You use statics. You get the specs for the crane and what it is lifting and determine from the site the pick angles and where the outriggers are going to be placed. Then you do the 3-D calcs to determine the reactions necessay and determine the soil's allowable bearing pressure, then design temporary footing based on that.
Q:Do you find it ironic a crane crashed into Mecca's holiest mosque on 9/11?
The big man with a beard got the co ordinates wrong.
