2. What was trying to be accomplished?? It was to compete with the Lusitania and the Mauritania. It was ship made to carry mail and passengers between Southampton and New York. It was supposed to be the fastest luxury ship, as well as the safest.

3. –The steel was not made for such cold conditions. –High amounts of sulfur, oxygen and phosphorus cause the metal to become more brittle. – Because of the cold water, the steel became more brittle, making it easier for the iceberg to cut onto the sides. –After the slits were made, they continued to tear as the water poured in, because of the brittleness. How it failed.. “Results of the Charpy test for modern steel and Titanic steel [Gannon, 1995]. When a pendulum struck the modern steel, on the left, with a large force, the sample bent without breaking into pieces; it was ductile. Under the same impact loading, the Titanic steel, on the right, was extremely brittle; it broke in two pieces with little deformation. “ - http://www.writing.eng.vt.edu/uer/bassett.htmlhttp://www.writing.eng.vt.edu/uer/bassett.html The Hull

4. The rivets were found with too much slag, causing the rivets to pop off much faster than they should have. This allowed the plates to be separated much faster by the incoming water. Slag is needed to fortify wrought iron, but too much makes it fragile and brittle. The Rivets

5. Possible Correction Actions Used a different method to make the steel. Inspected the quality of the materials used while building the ship.

6. Final Action Taken Engineering failure combined with fatal human error caused the Titanic to sink.
