What was titanic made of

This was done to assure strength in the center, where the maximum wave flex stresses were assumed to be located. Analysis of the steel rivets has shown good strength, but the wrought iron rivets contained an average of three times more slag than optimal levels. In addition, the slag was in large pieces. Both of these facts point to fabrication by inexperienced tradesman, as wrought iron was made by hand at the time. Finite element models of rivets made from sub-standard materials show that they were already loaded near their ultimate strength when installed.

The source of this poor quality material became clearer when the Harland and Wolff meeting minutes were examined, and it was seen that pressure to finish Titanic caused the company to order wrought iron that was one level below that generally specified for rivets and they had to use suppliers previously uncertified for this application. The collision opened six compartments to the sea, and she sank in two and a half hours.

In the area of the hull where most of the damage is contained, the seams consist of double rows of wrought iron rivets. Our supposition is that if the iron rivets had been of high average quality, or if the designers had opted for triple rows of rivets or to use steel instead of iron, then fewer compartments would have flooded. If it had been five compartments, with the Carpathia only six hours away, she would have stayed afloat long enough for most people to have been rescued.

If four compartments had flooded, she might have even limped into Halifax. We do not suggest that the ship would not have sustained significant damage in the collision if she had been built differently, but rather she would have sunk more slowly. And with the shortage of lifeboats, the time she spent afloat made all the difference in the tragedy.

Its final warning, sent at 11 p. A letter from Titanic survivor Laura Mabel Francatelli, with her account of the sinking of the ship. The ship was miles south of Newfoundland on April 14 1, miles from its final destination , when, at p. Experts say had only four compartments flooded, the ship would have stayed floating. The time between the first sighting of the iceberg and impact was a mere 37 seconds, with the ship sinking in minutes. Start your free trial today. An emergency cutter lifeboat carrying a few survivors from the Titanic, seen floating near the rescue ship Carpathia on the morning of April 15, hours after the disaster.

Most of the Titanic deaths were caused by hypothermia due to the low water temperature. According to the American Red Cross , a water temp of 79 degrees can lead to death after prolonged exposure, while 50 degrees can cause death in an hour, and 32 degrees can be lethal in 15 minutes.

Lifeboats on board the SS Titanic. When the liner sank in the Atlantic after hitting an iceberg there were only enough lifeboats on board to hold a third of the passengers and crew. However, the ship actually carried 20 lifeboats four were collapsibles which, according to Alpine's book, could only hold 1, passengers and crew, but that number was still more than required by the Merchant Shipping Act. Still, just over made it aboard lifeboats. This was certainly the case with Titanic.

As the ship's string band played, the ship sank to its watery grave, taking those not already in the water with it. Nearly 32 percent of those who had been aboard Titanic survived. One of the world's wealthiest men at the time, the first-class passenger, known for building New York's Astoria Hotel later known as the Waldorf-Astoria , Hotel St.

Regis and the Knickerbocker, drowned. His wife survived. According to the U. National Archives , her claim for loss of property included 14 hats, some 20 gowns, three crates of "ancient models" for the Denver Museum, along with an opera cape, two Japanese kimonos, jewelry and more. It wasn't until Sept. The debris field spread across 15 square miles with the hull buried under 45 feet of mud.

The discovery coincided with a top-secret Cold War-era investigation by the U. Navy to search for two wrecked U. Ronald Thunman, then the deputy chief of naval operations for submarine warfare, told National Geographic in that the Navy had permitted him to search for the ship once his mission was complete.
