An introduction to the analysis of an atomic bomb

Einstein had written to inform Roosevelt that recent research on chain reactions utilizing uranium made it probable that large amounts of power could be produced by a chain reaction and that, by harnessing this power, the construction of "extremely powerful bombs

Nuclear weapon - Wikipedia

The most destructive way of killing people known to man would have to be the atomic bomb. The reason why the atomic bomb is so destructive is that when it is detonated, it has more than one effect. The effects of the atomic bomb are so great that Nikita Khrushchev said that the survivors would envy the dead International Physicians for the Prevention of Nuclear War, An atomic bomb is any weapon that gets its destructive power from an atom.

This power comes when the matter inside of the atoms is transformed into energy. The process by which this is done is known as fission. The only two atoms suitable for fissioning are the uranium isotope U and the plutonium isotope Pu Outlaw Labs.

Fission occurs when a neutron, a subatomic particle with no electrical charge, strikes the nucleus of one of these isotopes and causes it to split apart.

When the nucleus is split, a large amount of energy is produced, and more free neutrons are also released.

These neutrons then in turn strike other atoms, which causes more energy to be released. If this process is repeated, a self-sustaining chain reaction will occur, and it is this chain reaction that causes the atomic bomb to have its destructive power World Book, This chain reaction can be attained in two different ways.

The first type of atomic bomb ever used was a gun-type. In this type two subcritical pieces of U are placed in a device similar to the barrel of an artillery shell. One piece is placed at one end of the barrel and will remain there at rest.

The other subcritical mass is placed at the other end of the barrel. A conventional explosive is packed behind the second subcritical mass. When the fuse is triggered, a conventional explosion causes the second subcritical mass to be propelled at a high velocity into the first subcritical mass.

The resulting combination causes the two subcritical masses to become a supercritical mass.

When this supercritical mass is obtained, a rapid self-sustained chain reaction is caused World Book, This type of atomic bomb was used on Hiroshima, and given the nickname "Little Boy" after Franklin D.

The second type of atomic bomb is an implosion bomb. In this type a subcritical mass, which is in the shape of a ball, is placed in the center of the weapon.

This subcritical mass is surrounded in a spherical arrangement of conventional explosives. When the fuse is triggered all of the conventional explosives explode at the same time.

This causes the subcritical mass to be compressed into a smaller volume, thus creating a supercritical mass to be formed. After this supercritical mass is obtained, a self-sustained chain reaction takes place and causes the atomic explosion World Book, A fireball is created by the blast, which consists mainly of dust and gasses.

The dust produced in this fireball has no substantial effect on humans or their environment. However, as the gasses expand a blast wave is produced. As this blast wave moves, it creates static overpressure. This static overpressure then in turn creates dynamic pressure.

The static overpressure has the power to crush buildings.English research paper parts introduction borreria latifolia descriptive essay budget speech analysis essay ambition in macbeth essay introduction research paper on space psychogeography essay help 8 page essay on racism in prisons essay za i przeciw energetyce sandra junglen dissertation meaning.

America’s decision to use two atomic bombs on the Japanese cities of Hiroshima and Nagasaki at the end of World War II has been a topic of intense debate for years following the incident.

The bombings of Hiroshima and Nagasaki are one of best documented historical events in history, while provoking lasting, fervently heated reactions.
