Question:
Answers:
do you know what density means?? water is a very densed and heavy material. Lets assume that the boat is a box cubic shape. and it weights 160,000 tons. thats 160,000,000 kilgrams, for the water to be its equal mass, 160,000,000 liter of water. density means mass/volum. the more dense sinks to the bottom. ur 160 kiloton ship, has a volume larger thhan 160,000,000 liter of volume, that means water is more dense, and the ship will float. If its smaller than that volume, that the ship will sink. That is why oil floats on top of water, because they have a lower density.
put it in common sense, i am sure 1 gallon milk jar filled with water will be heavier than the same jar filled with oil, even tho they have the same volume. on the same jar and you fill it with Mercury, you probably wont be able to lift it. While if its filled with air, it would be the lightest. The 160 kilo ton ship, regarless of how much it weight, we can assume it filled with air on the inside.
How does a boat made with metal float? but a coin made with the same type of metal sink? because if you crunch the boat together into one scrap metal, it probably will take up like 1/10 of its size...
Note: densenty determines float and sink, not weight...
Where can I find an affordable OMC 3.0 liter 4 cylinder to hook up to 1983 Stringer sterndrive?
it holds air and air floats.Why is the stering wheel on the right side of a boat?
because it has a large surface area and is round so water wont sink in but with the air pressure inside it helps keep it afloat!Marine Exhaust Systems? Headers?
You can also build boats out of concrete. Ship design. Can go on and on about the engineering but don't need to.In hawaii they make some science class students build boats out of milk cartons to show the principles of flotation and boat building. All the kids like that class as they race their boats after building them.
Are there any boating rivers in wales as i want to buy a boat but don't fancy boating on the sea.?
I think maybe they have hired a load of dolphins to carry it along underneath.....To put it simply, the amount of water the ship displaces is greater than 160,000 tones so the ship floats.
Does anyone know a good or bad boat surveyor in the Annapolis, Solomons, Deale, Maryland area?
It all has to do wth buoyancy. A penny is not very buoyant, for the sides are flat, which allows the weight of the penny to overcome the force of the water pushing up on it, and so it sinks. A ship's hull, however, is curved, allowing the water to flow up it it when the hull pushes it until the buoyant force and the weight of the ship are at an equilbrium with each other (the force of the water equals the weight, so it is in balance) allowing the ship to float. The water pushed aside is called the displacement, and a ship considerably smaller, weighing 46,000 tons, RMS Titanic displaced 66,000 tons of water, considerably more than the ship's weight.Where do all the damaged boats from hurricanes end up?
The answer is that there is more weight in water than there is weight in a ship. I don't know exactly why the penny sinks. Maybe its because once water gets on top it sinks. That's my guess. You should re ask this question in the science area maybe in physicsIts the principle of buoyancy. The same force that pushes bubbles to the water's surface also keeps these 160,000 ton monsters up. Anything with a density less than waters will float, and it's true that like your penny, the iron and steel used in these cruise ships are denser than water. But they are displacing the water and the water doesn't want that, so it pushes it up. These ships unlike your penny, are filled with air which is combined with the steel to give it an overall lighter density.
What is the fuel ratio for a 7 horse power boat motor?
For a good but rather long expanation to your question, take a look at Archimedes Principle.Whats the diffrence between a ship and a boat?
Wikipedia has the answer.
http://en.wikipedia.org/wiki/buoyancy...
So if a boat weighs 1,000 pounds, it will sink into the water until it has displaced 1,000 pounds of water. Provided that the boat displaces 1,000 pounds of water before the whole thing is submerged, the boat floats.
I wanna buy a frigate from the age of sail?
It is not very hard to shape a boat in such a way that the weight of the boat has been displaced before the boat is completely underwater. The reason it is so easy is that a good portion of the interior of any boat is air (unlike a cube of steel, which is solid steel throughout). The average density of a boat -- the combination of the steel and the air -- is very light compared to the average density of water. So very little of the boat actually has to submerge into the water before it has displaced the weight of the boat.
It displaces more weight in water than it actually weighs. Example, the ship weighs 160 tons. The amount of water it displaces when sitting in the water will weigh more than 160 tons, hence it's lighter than water.
Does anyone have plans to build a floating dock approx. 20' x 12'?
