Titanic and the SS Maheno. The well know ship “The Titanic” now lies 3,800 m under water off the shore of Newfoundland where it sunk back in 1912 after colliding with an iceberg, the ship is now rapidly rusting and disintegrating. The SS Maheno is a major tourist attraction that lies on the east coast of Fraser Island, Australia. It was a trading ship between New Zealand and Australia from years 1905 to 1935, and also participated in World War I for the New Zealand Naval Force. The wreck was left there to disintegrate after the owners refused to pay to move it. Corrosion is ‘a chemical process by which a metal is oxidised. ’ (corrosionist.com). Iron is the only metal that rusts and occurs out of the chemical processes, oxidation and reduction. In most cases, corrosion of iron occurs when the metal is losing its electrons, this is oxidising. Another cause behind the occurrence of rusting is ‘rust eating bacteria’ at deep enough levels of the ocean. And finally, abiotic factors such as salinity, pH and oxygen levels have an impact on the rusting or shipwrecks. The last cause to be discussed is environmental effects such as salinity, pH and oxygen levels. …show more content…
Iron is naturally iron oxide and purified iron rapidly returns to a similar state when exposed to air and water. This whole process can be seen below in figure 3 – ‘The corrosion
Stainless steel, especially, Austenitic stainless steel, because of their high corrosion resistance and customizable mechanical properties has become an indispensable part of the regularly evolving modern day technology. Stainless steels of various grades find applications in numerous fields starting from the household to the nuclear reactors; from food and beverage cans to construction of different automobile parts. The formation of impervious oxide layer on the surface makes it suitable for use in adverse environments such as sea water.
The Great Lakes have been home to more than 6,000 shipwrecks on its five major Lakes (Childs, 2011). One of the most popular wrecks was that of the bulk freighter the Edmund Fitzgerald on the Canadian side of Lake Superior. It had transported goods across the Great Lakes for about 17 years before it was overcome by the power of the Lakes. In terms of lifetimes of shipping vessels, The Fitzgerald was still relatively young. “The Fitzgerald, often called the Titanic of the Great Lakes was not only the most famous freshwater shipwreck; it was also the biggest mystery in the Great Lakes history” (Schumacher, 2006). Weather played a key role in the defeat of this ship and the death of all 29 hands on November 10, 1975. “Winter is a time of intense
April 14, 1912, the Titanic set sail for a maiden voyage. Some of the people on board never thought that it would be goodbye forever. The Titanic was heading to New York City from Southampton, England. Why does the Titanic now lay at the bottom of the Atlantic Ocean? Historians believe that the Titanic sank because of human error. They believe that it was Captain Smith, the lookouts in the crows nest, and Thomas Andrews fault.
In 1996, treasure hunter Brock Lovett and his team aboard the research vessel Keldysh search the wreck of RMS Titanic for a necklace with a rare diamond, the Heart of the Ocean. They recover a safe containing a drawing of a young woman wearing only the necklace. It is dated April 14, 1912, the day the ship struck the iceberg. Rose Dawson Calvert, claiming to be the person in the drawing, visits Lovett and tells of her experiences aboard the ship.
Imagine you’re peacefully sailing along on a giant cruise liner in the middle of the ocean. But suddenly, you feel a shaking and the boat starts to tip. But how could this be? This boat is supposed to be unsinkable. People run to the far side of the boat, trying to avoid impending doom. Panic sets in aboard the Titanic. There are many theories of the cause of this loss of life, but I believe that the primary cause of catastrophic loss of life on the Titanic was the poor communication between crew members because a critical iceberg warning was never delivered to the captain, the Titanic was traveling at full speed in an ice field, and the captain of the ship was very relaxed about the iceberg, making it not seem like a threat.
The titanic was a gigantic ship. It was the biggest, newest, and advanced ship during its time. The titanic was built in Belfast with the newest and best technology. Then after its completion it would travel to New York. During the tragedy of the Titanic the engineers had a key role on saving people. Although the tragedy of the titanic was sad it taught us many lessons on preventing such a thing again. Although the titanic has sunk to the bottom of the ocean it will never be forgotten.
Including that the ship's steel plates were excessively weak for the close solidifying Atlantic waters, that the effect made bolts pop and the extension joints fizzled, among others. Technological parts of the calamity aside, Titanic's downfall has gone up against a more profound, practically mythic. Many view the disaster as a profound quality play about the threats of human hubris: Titanic's makers trusted they had fabricated a resilient ship that couldn't be crushed by the laws of nature. The shock was driven not slightest by the survivors themselves; even while they were on board Carpathia on their approach to New York, Beesley and different survivors resolved to stir popular conclusion to defend sea go later on and composed an open letter to The Times encouraging changes to sea security laws. In places nearly connected with the Titanic, the feeling of misery was
The RMS Titanic sunk more than 100 years ago. It was 102 years to be exact. Even after all of this time, we still want to know more. We want to know why it happened or was there any way to avoid the sad ending and many more questions surrounding the RMS Titanic. However, we know one thing for sure: the sinking of the RMS Titanic was the biggest and most tragic event of the 20th century.
Damage beyond the hull was also witnessed that allowed for the influx of water. Whenever the forepeak tank was damaged, “six watertight compartments flooded with water, causing the ship to sink faster than it should have,” (Bassett). The Titanic, being the largest ship at this time, should have stayed afloat for two to three days after striking the iceberg. Within three hours, the Titanic sank, which never should have
Drowning, screaming, Weeping, Send offs...These are some of the last words you heard from Jack Jill, Tyrone T. lll, Bob Blob and from others. The date was April 14-15 1912. The zone around North Atlantic Ocean. This was traumatic time/date. The Titanic had sunk and lots of people died 1,503 to be exact. But these people were rude, raw and blunt. And also the rude rich ones ended up dying. But not all of them died. It is kind of funny because the rude rich people were the ones that died. AKA people like Jack Jill and Bob Blob. The Titanic was on her maiden voyage, a return trip from Britain to America. The route was Southampton, England – Cherbourg, France – Queenstown, Ireland – New York, USA. The return route was going to be New York – Plymouth,
The tragic history of the Titanic, the sinking of the “unsinkable” giant of a ship shocked the entire world and contributed to important shifts in the mass consciousness of the people who lived at that period and assessed the achievements of new technologies and their role. However, one would have been hardly able to predict in 1912 that this tragedy, no matter how significant and meaningful, would leave such a deep imprint on the history of human civilization. The continuing interest in the fate of the great vessel has taken the form of various narrations and given rise to numerous myths enveloping the true history and, in this way, often obscuring the facts related to the tragedy. In recent years, this interest has been emphasized by the dramatic discovery of the wreck and examination of its remains. The recovery of artifacts from the Titanic and the exploration of the site where it had sank stimulated new speculations on different issues of the failure to rescue the Titanic and the role of different factors contributing to the disaster. These issues have been traditionally in the focus of discussions that caused controversies and ambiguous interpretations of various facts. They also often overshadowed other parts of the disaster story that were confirmed by statistical data and revealed the impact of social realities. The social stratification of passengers that reflected the social realities of the period and its class interests determined the chances of survival, with most of those perished in the Titanic disaster having been lower class individuals.
the iron ore to iron. In the other cases of metals the most common way
By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
Tests on Titanic's steel showed that the steel had high sulfur content, which increases the brittleness of steel by disrupting the grain structure [Hill, 1996]. This increase in brittleness contributed to the severity of the hull's
The beginnings of modern processing of iron can be traced back to central Europe in the mid-14th century BC. Pure iron has limited use in today’s world. Commercial iron always contains small amounts of carbon and other impurities that change its physical properties, which are much improved by the further addition of carbon and other alloying elements. This helps to prevent oxidation, also known as rust.
