with a ladder type cage all around them. they rise up and down. What I want to know is mechanicly speakinh how do they work?

They are known as gasholders (or gas holders) and gasometers.

This is really a question that Architects and Structural Engineers have been trying to resolve. The problem is that the more that you go up, the more pressure you place on the earth, as well as the increase of size of columns that are required at the lower levels. \n\nThe ultimate theory of a skyscraper (though not really a building) is a space elevator, or a conveyance system from the earth to a space station in geosyncerous (sp) orbit.\n\nOne thing is for certain: as new materials are being created & discovered (carbon nano-tubes), skyscrapers will get higher and higher.

Through hole mounting.  If they have leads you will have to solder them on using a soldering iron.\n\nhttp://en.wikipedia.org/wiki/Through-hole_technology

Ones upstairs and the other is down stairs!\nLOL

Those are the ones that spin up into the air... Some of them, they have on sticks attached to the ground..they just spin on the pole. Lots of times they whistle too

INcredible.. The first question I've seen where everyone is right.\nYes, they are connected to the ship through strapping and bolts at the corners..\nThey do fall off. but very rarely and some are neutral buoyancy and the cause of many small ships foundering.. Usually, whale attacks get the blame.

Do your home work. \n\nStill I tempt to answer this question.\n\nW= weight of the box\nmu= coefficient of friction.\n\nWe assume there is no acceleration. So force to upward movement is Fup = Wcos(20)*mu + Wsin(20),\n\nsimilarly Fdown = Wcos(20)*mu - wsin(20),\n\nso\nWcos(20)*mu + wsin(20) = 4Wcos(20)*mu - 4wsin(20)\n5Wsin(20) = 3Wcos(20)*mu\nmu = 5sin(20)/3cos(20)\nmu= 5/3 tan (20)\nmu = 0.606

GOD!!!!!!!! These people who answered are retarted!!!!! itS NOT THE SQUARE BUTTON!!!!!! I have the game and i know the new controls. so the ladder is standong up right?? Well if it is then you press x. Then you just run into the ring with it in your hand.

They actuate a type of selonid \n1 should be Hot and 1 should be ground

They have pyramids.\n\nCoach

jgardn said "The vertical growth of plants is actually stimulated by sunlight."\n\nThe vertical growth of plants is due entirely to the effects of gravity. You can demonstrate this yourself in a number of ways. The simplest is just to take some bean seeds and germinate them in the dark. No matter how often you turn them they will always turn upwards, depsite having no light at all. You can then place the seedlings in a box with alight source beneath them or beside them. Athough the seedlings will grow somwhat towards the light they will continue to grow primarily upwards.\n\n\nPlants will grow towards light, but that is not what determines vertical growth.

I wondered about this a few years ago...found the solution online.  Very cool engineering trick.  I rememebered where I found the solution.  The cranes grow themselves.  Check out the link below...with pictures.

how do u think they get up from those awesome belly slides they love to do? they push up from the ground with their beaks and front wing things and they can stand up.

Why would you even consider stooping to their level.  You're bigger and better than that.  Just let them be.  And the remember the saying "The wheel Turns" - w/o you doing anything...one day down the line...something bad will happen to them too...it might be tomorrow, or 10 yrs from now...just rest assured that it will happen

Sorry, but you'll need to give a little more information. How are the pulleys and weights arranged? Just a little picture would help.\n\nTypically, pulleys, weights, tensions and accelerations are extensions of the block on an incline problem except the pulleys are providing the force vector direction change.\n\nIt might help to think of the problem as a sum of vectors and look for where their vector sum lies.

Most racks have floor mounting kits that attach to the rack and bolt to the floor. These are installed after either removing or retracting the wheels on the bottom.

they fly by sunlight so the go to the direction the sun is coming from also the have very small brains so they ain't very good at problem solving :P
