Why do submarines have to be strong?
Submarines would need thick, strong walls because They would have to withstand the pressure of the water that would increase the deeper they go, to do this they would need stronger and thicker materials to cope with the force (This would help keep the people safe).
Does a beagle need a special place to live?
They need a house or apartment with thick walls.
Why submarines need a thick hull to go deeper?
Because thin metals will crush under extreme depth
Why does the uterus have thick muscular walls?
The uterus has thick walls because a fertilized egg would need a thick lining in order to implant and begin to grow and develop. The uterus is sterile and has no bacteria present, however large quantities of debris and bacteria is brought into the uterus with the sperm. Therefore, the walls must be strong and muscular because uterine contraction has to occur to expel fluid, dead sperm and bacteria out from the uterus and through the open cervix.
Why are the walls of arteries proportionately thicker than those of the corrosponding veins?
Artery walls need to be thick because they have to cope with high pressures produced by the cardiac cycle, the arterys are made thick by cardiac muscle.
Why are submarines built of hard thick sheet of metal?
Because they need to be able to withstand the pressure of the seawater outside. The deeper a submarine goes - the higher the pressure gets.
Why do arteries need strong walls?
Because it have a pressure it must pump the blood and carry it away from the heart
Why do submarines need fins?
For stabilization
Why you need pressurized cabins in submarines?
If the pressure of the water is greater than the air pressure inside the cabin, the walls will crack, the doors will open, water will pour in and the submarine will sink to the bottom of the sea/lake, flooded. ("walls and "doors" are improper words, bear that in mind).
Why are submarines important?
submarines are important because people need to go under the sea and do what they got to do to save the world
Are poured concrete walls better than concrete block walls?
It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.
Why are atria so thin-walled?
The atria does not need to be very thick because all it needs to do is fill up with blood so that the ventricles can pump out the blood. The ventricular walls are thick so that they can properly pump out blood to the needed areas.
