The density of the wood panelling is key in our study as this will determine the mass of the panel, which is an important factor on whether the panelling will sink or float.
We can immediately deduce some bounds on the density, thanks again to the Maritime Museum of the Atlantic in Halifax. According to the museum the piece of panelling is made of oak. The volume of the panel in Figure 9 can be found by calculating the volume of the three individual sections which make up the panel. The salinity of ocean water varies with location. The Atlantic Ocean, where the Titanic sank, varies between 33 and 37 parts per thousand.
First we consider the case which occurred in the film, Rose lying on the panelling. To do this we consider the forces acting upon the panelling, the downward force due to weight, and the upward force due to buoyancy. The only variable we do not know is the displaced volume.
Since we know the area of the panel which is in contact with the water we are left to find the height that makes up the submerged portion of the panelling. Thus we actually find the depth to which the panelling sinks, clearly we require this to be greater than the total depth of the panel, in order for some of it to remain above water. Thus, using our assumptions, Rose could not have floated on top of the panel and been completely above the water.
However, since the only real knowledge of this system is that Rose can float on the panel we must adjust our assumptions. The first assumption to try changing would be our choice of wood density, since this was chosen to be the midpoint of a fairly large range. By rearranging Equation 5 we can plot a graph of densities against how much the panelling would sink:.
This is a reasonable value, especially when you consider the Figure below:. However, it is likely that should they both have been on the panelling, they both would have survived especially if they had sat. Human survival time in cold water. The curves in the Figure indicate the expected survival times at different levels of body insulation in cold water.
The panel was then lowered into the water, and at first, Jamie got onto it. Like the miniature test, and the Titanic movie, the piece of floating wood panel did sit on the water nicely, but there was some sloshing onto it. Now, it was time for Adam to climb on board. The first time Adam got onto the wood panel with Jamie, it did tip up like it did in the movie, but then they were able to balance it out.
Believe it or not, the wood panel was big enough , and buoyant enough, to handle the two men, and it stayed afloat long enough for them to be rescued just like Rose was in the movie.
There are millions of Jack Dawson fans who should now feel satisfied that it has been successfully proven that the panel was big enough for both Jack and Rose. However, Jack was not willing to risk Rose ending up in the water where she would more than likely freeze, and he bravely stayed in the water, and ultimately met his death.
While it is unfair that Jack died when he clearly did not have to, the fact is that James Cameron explained it best when he said that the death of Jack helped Rose become the person she was always meant to be. Though it is sad that Jack died, the two of them were ultimately reunited in death, and would spend the rest of eternity together….
Under the command of Edward Smith, the ship leaved Southampton with passengers aboard, including some of the wealthiest people in the world, as well as hundreds of poor emigrants from Europe seeking a new life in North America. The ship had advanced safety features, but there were not enough lifeboats to accommodate all of those aboard. Only 1, people can be carried in lifeboats. Four days into the crossing and about miles km south of Newfoundland, she hit an iceberg at pm ship's time.
