how to raise the titanic? Answered

 From this suggestions , can the titanic be raise?

1.Fill with table tennis balls.

2.Using nitrogen , make an ice block to float the ship.

3.Make crane-boat the winch the ship.

4.Using giant rubber to raise it.

Build a caisson around it, Pump out the water, stabilize it, Apply anti-microbials to it such as aldehydes and alcohols, but NOT chlorates, apply rust-proofing to it, attach huge helium filled gas tanks to it, pull her to a dry dock, then worry about what to do with it.

 This is my assignment . So , i must make the calculations . But, i didn't know to do . I need your opinion and calculations . Can you all help me?

This all sounds like basic archimedes principle to me, though of course its completely out of the question, even leaving aside the fact its the tomb for 1200 people.

Find out how heavy Titanic actually was.

Steve

 Can you show me the calculation of the 4 ways in the question . I'm really don't know the physics subject . Please help me .

Come back and tell me how heavy the ship was,  AND its displacement. They are not the same, are they ?


Steve

 Yes. They are not same. The gross tonnes was 46,328 tonnes and the displacement was 52,310 tonnes. The length was 882 ft 9 in.(269.1m). The height was 175 ft (53.3m). The beam 92 ft (28.0m). How to calculated that?

and part of the ship has been eaten by deep sea bacteria

Now you need to figure out the top area, and from that calculate how much resistance the water will give you.
Also figure out the volume of water that would fill it, calculate its weight, and add it to the total mass of the ship.

That should be enough to get you going I think.

 How to calculated that?.
Must figure the area of the top of the ship?.
How to calculated the water resistance?.
The volume of the water can be calculated by the volume of the ship right?

1) area = length*width (use the rectangular area unless you can find published data somewhere that is a cite-able resource)
2) same as calculating air resistance except you replace the value of air resistance with the resistance of water (google something about "viscosity" if you have trouble)
3) volume of water = former volume of air. just add the weight of that amount of water.

My first comment there was just ideas off the top of my head, if your professor will let you ask him/her questions of weather or not you're pointing in the right direction, do so.

i'm glad you all help me. From that all answer, i'm use it to do the work. So my work are done. Thanks for the helps.

If it's your assignment, and you're lost, ask your instructor for a few hints.

1) Fail. The balls would crush halfway down and it would, if possible, take an ungodly amount of balls to do it.
2a) High potential for failure. Defiantly don't have boats above it on even close to it, if the gas bubble ruptures, it would destroy that ship.
2b) An ice block? really? That would need one hell of an iceberg, and given that they sunk it once, it would be really awful if they sunk it again.
3) Possible, but very likely to fail. Getting the straps under the ship would be a heck of a challenge and the ship might be so corroded that you might really want a basket to raise it in. Also, the weight of the ship combined with the weight of the water and the resistance of the water would make it take days, if not weeks to raise it properly.
4) Fail. Its almost freezing down there, and rubber + cold = snap. Also, that much rubber would not only cost a mind blowing amount, but there is no way to produce the amount necessary in a timely fashion.

My consensus? Just leave her in her watery grave, its better that way.

 Can you tell me in details.
This can help me to do my assignment.
First of all,thank you because help me.

Re: #4

Man, that would be one big rubber.

Is that one of those weird British things? Why can't you folks learn to speak English? ;-)

 Can you show me the calculation of the rubber?. to raise that ship with physics formula.

First you need to find big enough pieces to be worth raising. Then it needs to be in shallow enough water to rig for raising. Given those prerequisites, there are fairly standard techniques for dealing with this sort of recovery; a bit of websearching will find more information about them.

 Can you tell me details?. I really don't understand.

 Can you show me the calculations . I'm really don't know the physics subject . Please help me .

#1 won't work.  Get enought tt balls inside to raise it and those on top would be crushed by the force of those on the bottom releasing the air and loosing buoyancy.

Can you show me the calculation of the 4 ways in the question . I'm really don't know the physics subject . Please help me .

As Lew Grade said, it would be cheaper to lower the atlantic.

Lease the Glomar Explorer-the ship Howard Hughs built to steal a sunken Russian submarine.

It's in bits, and why?
Pinky & The Brain succeeded though...

 culturespy is right but lets say no one died in it it would be practically impossible because it is so eroded but yes you could lift a sunken ship with all of those ideas (not sure about #1) 

Yeah, It's already pretty crumbly and is considered a monument, even a grave, for the people who lost their lives when it sank. So, if we had the technical ability to bring her up there would still be a moral conflict in doing so. 

I think the real trick would be building a working full size replica that daring passengers could cruise on! 


Build a replica, submerge a few feet below the surface, float the replica up with lots of photos and huzzahs, destroy the real one.

Given its current state of decay, none of those would work.  The Titanic is in such a state of deterioration that almost any attempt to move it would result in it falling to pieces. 
A giant clam shell type scoop that could reach completely underneath the structure might work, but just the jostling around of moving it would probably cause it to crumble.

The wreckage is in multiple pieces.  The Mythbusters solution (original credit to Donald Duck) requires an intact, but submerged, vessel.
