The Titanic was the biggest ship ever built when it was being built. It was 230 metres long, 25 floors tall, and 46,000,000 kilogrammes. The turn-of-the-century engineering made her unsinkable by including sixteen sizable watertight compartments that could readily be sealed off in the case of a hull breach.
Reason for its failure :
The collision of RMS Titanic with an iceberg on April 14–15, 1912, led directly to the fate on ocean liner. The hit had apparently compromised up to 4 of the 16 ship compartments, but at least 5 compartments had been effected. At first, it was thought that the iceberg had sliced a lengthy gash through the hull.
However, after investigating the wreck, researchers found that the accident had left a number of tiny gashes as well as brittle fractures and seam separations in the nearby hull plates, which allowed water to enter the Titanic. Later analysis of the salvaged ship pieces and documentation from the builder archives led to the theory that shoddy steel or weak rivets may have been a factor in the ships sinking.
Approximately 1,500 of the ship 2,200 passengers and crew members are thought to have died when the vessel sank. The U.S. commission looking into the disaster found that 1,517 people died, and its British equivalent found that 1,503 people died. With around 700 fatalities, the crew was the group that was most heavily hit. Only 174 of the roughly 710 passengers in third class survived, so they too suffered immensely.
