WHY DID THE TITANIC SINK?

 



An estimated 10000 people gathered at the dock in the belfast on march 31 1911 to watch the launch of the Royal Mail Ship ( rms) Titanic. Titanic was considered to be an unsinkable ship. It was the largest and most luxurious cruise liner of its time. It was 882 feet long and 175 feet high and weighted more than 46000 tons. It boasted a state of the art technology , including a sophisticated electrical control panel, four elevators and an advanced wireless communication system that could transmit morse code.

Titanic was made up of 1-inch-thick mild steel plates and 2 million steel and wrought rivets. It was designed to be virtually unsinkable, to stay afloat with four to 16 watertight compartments open to the sea.

Yet on the night of April 14, 1912, just four days after leaving Southampton, England on its maiden voyage to New York, the titanic struck an iceberg off the coast of newfoundland and sank.

Why? Experts have stated many reasons like :-

  1. It was travelling too fast.
  2. The wireless radio operator dismissed the key iceberg warning or the warning came late to take necessary actions.
  3.  It may have taken a fatal wrong turn.
  4. The Titanic’s builders tried to cut the cost by using non appropriate materials.
  5. The most appropriate reason considered is brittle steel used in titanic made it sink.
  6. The safety norms were not stringent to make titanic equipped to tackle the disastrous situation.

 

Can steel be brittle? ðŸ™„

The steel from titanic was further analyzed for chemical components and was found to contain high levels of oxygen and sulfur. The steel was semi kilned, low carbon steel made using open hearth process. High sulfur content disrupts the grain structure of steel leading to an increase in its brittleness. While the material is normally quite ductile, the addition of oxygen causes the material to transition from ductile to brittle in nature. The ductile to brittle transition temperature of this steel was determine as 25 to 30°C .

DUCTILE TO BRITTLE TRANSITION

 At certain conditions, some materials that are ductile become brittle.

1)   Low temperature

2)   Triaxial State of stress

3)   High Strain rate

 

All these conditions can make a ductile material go brittle and eventually crack.

With the titanic, these conditions prevailed! On the night of the disaster all these three factors where present . The water temperature was below freezing, the titanic was travelling at a high speed on impact with the iceberg, and the hull steel contained high levels of sulfur. It is where the chunk of iron discovered during the expedition played a major role in providing that the brittle fracture of the hull of the steel contributed to the disaster.


       Let us have a look on some of the parts of titanic existing below the sea.

Convolutional Neural Networks

   An introduction to Convolutional Neural Networks   Introduction: What is an artificial neural network? In recent times, words like deep learning, machine learning and artificial intelligence have become so common that even school kids are now somewhat familiar with these terms. The advent of Machine Learning has been followed by the rise of Artificial Neural Networks (ANNs). ANNs are computational processing systems used to handle a large amount of data. They take inspiration from the way biological nervous systems operate. These neural networks have a number of hidden layers stacked upon each other. The basic computational units of a neural network are called neurons. Just like neurons in the human brain, these fundamental blocks take in input signals, process them and produce the output. Figure 1 below shows the basic structure of any ANN architecture: Figure 1 What are convolutional neural networks? In this article, we will focus on Convolutional Neural Networks (CN...
