Challenger High Pressure

As impressive as some may seem to our modern inventions, there is always an opportunity for our designs to fail. To err is human, as the old adage. efforts important as the design and construction of a new building, based on the collective knowledge of hundreds of individuals. That said, the success of any project will depend largely on the weakest link in the chain of knowledge. This is precisely the reason jobs in mechanical engineering are in such high demand. The following is a compilation of the five worst engineering failure in the modern era.

Space Shuttle Challenger disaster

On 28 January 1986 the space shuttle Challenger disintegrated off the Florida coast, killing all seven astronauts. It is believed that an O-ring on the right solid rocket failed, causing a gap in the joint to ensure hot, pressurized gas from inside the rocket engine to escape. This led to the structural failure of the external tank and precipitate, with the assistance of the aerodynamic forces, the breakdown of the vehicle. The fact that the O-rings was attributed to faulty design of the Commission Rogers.

Chernobyl Nuclear Meltdown

On April 26, 1986, the world witnessed the worst nuclear power plant disaster in history at the nuclear power Chernobyl in Ukraine. The resulting explosion (s) resulted in the release of significant amounts of radiation into the atmosphere, producing more than 400X consequences more than the bombing of Hiroshima. While human error may have played a role in the disaster, defects in the design of the control rods are believed to have been the root cause the accident. Authorities are still largely unsure of the effects of exposure to radiation, and the area remains heavily contaminated after more than 20.

New Orleans levee system

In August 2005, a series of hurricanes hammered the areas in and around New Orleans, Louisiana. Were believed to more than 50 individual failures in the systems of levees and floodwalls to protect the city of New Orleans. These levee failures contributed to the flooding of over 85% of the city, with some areas under three meters of water or more. In 2006, the U.S. Army Corps of Engineers, in testimony before the Senate Subcommittee on U.S. Energy and Water, acknowledged that there were "problems with the design of the structure." New Orleans, Louisiana is still a disaster area to this day.
