What was the largest explosion in recorded history?
Tsar Bomba
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
What causes bridges to collapse?
The most common causes of bridge failure are structural and design deficiencies, corrosion, construction and supervision mistakes, accidental overload and impact, scour, and lack of maintenance or inspection (Biezma and Schanack, 2007).
Where did the most powerful explosion ever witnessed on Earth occur?
One of the most powerful volcanic eruptions in recorded history occurs on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27, 1883.
What is the lifespan of a bridge?
The average bridge in the U.S. is 43 years old. Most of the country’s bridges were designed for a lifespan of 50 years, so an increasing number of bridges will soon need major rehabilitation or retirement.
What is aeroelastic flutter on a bridge?
Aeroelastic flutter, defined as “an unstable, self-excited structural oscillation at a definite frequency where energy is extracted from the airstream by the motion of the structure”, is ubiquitous in a wide range of engineering fields.
What is detonation?
Detonation (from Latin detonare, meaning ‘to thunder down’) is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases.
What is the detonation of a spark?
For detonation in spark-ignition engines, see Engine knocking. Not to be confused with Denotation. Detonation (from Latin detonare ‘to thunder down/forth’) is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it.
What is the difference between shock wave and detonation?
The initial shock wave is visible on the water surface, and a shock condensation cloud is visible overhead. Detonation (from Latin detonare, meaning ‘to thunder down/forth’) is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it.
What is the history of detonation theory?
The mathematical predictions of propagation were carried out first by David Chapman in 1899 and by Émile Jouguet in 1905, 1906 and 1917. The next advance in understanding detonation was made by Zel’dovich, von Neumann, and W. Doering in the early 1940s.
