Q:what is this song on this video?

el capitan - silo song

Q:A piece of ice at the very top of a round silo dome slides off one side. Assuming there’s no friction between the ice and the dome, at what angle θ from the vertical would the ice lose contact (i.e. n= 0) with the silo?

The only force when it loses contact is gravity (mg) R is radius of dome Fnet = ma mg = mv^2/R g = v^2/R Rg = v^2 Now, we have to find how far down the sled goes in order to reach that velocity. h is vertical distance traveled by block I will call that Work energy theorem: Wnet = Kf - Ki mg(R-h) = .5*mv^2 mg(R-h) = .5*mRg R-h = .5R .5R = h So, the block has gone down half the radius of the dome From this we can extrapolate a right triangle that has a height of .5R and a hypotenuse of R. This can be recognized as a 30-60-90 triangle, so the answer: 60 degrees = θ

Q:A grain silo has the shape of a right circular cylinder surmounted by a hemisphere. If a silo is to be constructed to have a capacity of 2000 cubic feet, then what height and radius of the silo will require the least amount of construction material?So far all i have is 2000 = (4*pi*R^3)#92;6 + pi*R^2*Ythen i solve for Y and get (2000-(4piR^3#92;6))#92;piR^2 without simplifying of course, anyway when i substitute Y in the volume equation i get the only possibility is X = 1, but i was under the inpression there should be more than one possibilities because that would make for a 600 some foot tall silo, plus tells nothing of building material unless i compare the findings to the total areas of other combinations.The silos radius must be equal to the cylinders so im not sure. Thanks.

okay, the problem with your substitution, is that it cancels out all variables. The pi*R^2's cancel out, and so do the other variables, leaving you with 2000 = 2000 The important thing to notice is the least amount of construction material. In mathematical terms for this equation, it means the surface area of the general dome + hemisphere shape (disregard support beams or whatnot that would be used in actual construction) For this problem, the surface area of the silo would be 2piR^2 (hemisphere) + 2piR*Y (cylinder) = A use that information and see if you can come up with a better answer. =)

Q:I dont know this.Thanks!

Any good airtight storage structure can be used-oxygen-limiting silos, conventional upright silos, bags, bunkers, and trenches. An airtight seal over the top is recommended; additional reinforcement may be necessary.

Q:I say invade but not try to conquer the shithole just take out there nuclear silos and mobile launchers topedo there subs take our there nuclear facilities so they cant make more nukes im saying this beacause they are a huge threat to our national security should we. Real honest questions only

Russia has 5 million troops Usa would need at least 6/7 million soldiers while Usa have less than 2 millions

Q:and if the Usa is attacked with an EMP?if a nuclear bomb explode in the Usathe bombs in the nearby America explode too?

Our nuclear silos can withstand a direct hit and not be effected.

Q:has anyone made a swimming pool out of a silo?

Never seen it done before, but I have heard of a couple of people that have wanted to before. I would think it would get really pricy. I would think long and hard on that one dear, and good luck to ya !

Q:RAF Spadeadam was home to the Blue Streak missile programme (the missiles were tested in Woomera Australia)I think construction began on one silo at RAF Spadeadam before they decided to ditch Blue Streak as a nuclear detterant, was the silo ever completed? are there any photos of it? what would the silo have looked like (as in blueprints, if available don't know if still secret)?

I'm as proud a Brit as anyone, but I'm afraid the Germans were way ahead of anyone when it came to missile silos. One of the most (in)famous is La Coupole (The Dome) in northern France. An underground complex of factories, fueling depots and 'silos' connected by (standard gauge, no less) railways it was built to store, fuel and lunch around 50 A4 (V2) rockets a day against London and the invasion ports. It's also believed that it was designed to be capable of launching the proposed A10 rocket which, had the Germans ever finished building, would have been fired on New York. This makes it arguably the first ICBM silo complex in the world, and certainly one with a better claim to the title than anything us Brits built. However, just to show I'm not short on Jingoistic pride..... In 1943 the USAAF were given the mission of destroying La Coupole. Despite valiantly attacking the site multiple times (on occasion with over 500 bombers) over a 2 month period (March to May 1943) and dropping 4,000 tons of bombs they failed to cause any appreciable damage and declared the site impenetrable to air attack. Consequently in June the job was passed to 617 squadron of the RAF (The Dambusters). 3 attacks were aborted due to bad weather, but on in late July using 'just' 12 Tallboy (12,000lb) bombs, 16 Lancasters of 617 caused so much damage that the site was abandoned forever. Cheers

Q:it has recieved very little attention. but, there are apperantly 15 radioactive hot spots in the area of the quakes epicenter. do you think its a quincidence that china keeps ICBM silos in the same area? i think some ICBMs/ were damaged in the quake. do you have any info on this?

INTERESTING I've not heard about this do you have any links to more into on this? much appreciated >>>>>>> thanks for the link Obviously other countries will be watching the satellite pix about this (and governments get better resolution than GoogleEarth does). The weapons resarch place is a worry, as it does look quite close to the epicentre. ICBMs I think would be safe though...not that we'd be told where they are located, but these missiles are not left for years in the silos with the nuclear warheads attached...they only get put on as needed. This is because there is a much bigger risk of problems with rusting and THEFT.(Some Russian ones supposedly went missing after the USSR broke up, leaving some missiles behind in what became separate countries). Anyway a warhead has to be exploded (internally) for the nuclear reaction to start. Or the shieldng to crack for radioactivity to get out. The research places are more like nuclear power plants are....the radioactive rods are there with only water over them, and any leak could expose them. I do hope they made that building earthquake proof, I'm sure they spent more on it than they seem to have spent on some of the schools.

Q:Does anyone know where i can buy warheads in ottawa?! i love them but i can never find them anymore
