To prevent premature detonation the fuel had to be kept in separate sub critical masses which shall not support the fission reaction. The biggest challenge with designing the bomb was bringing together these subcritical masses to produce a supercritical mass which will provide more than required neutrons to sustain a successful fission reaction at the time of the detonation. The easiest way to bring the subcritical masses together was to develop a gun that shall fire one subcritical mass into the other. A small pellet of U-235 (subcritical mass 1) is removed from a sphere of U-235 (subcritical mass 2) that surrounds the neutron generator and placed at one end of a long tube in front of explosives, whilst the sphere will be placed at the opposite end. A barometric-pressure sensor will decide on an appropriate altitude for detonation that initiates a sequence of
The document explains that "The Japanese were already defeated and ready to surrender..." (Document F). The document explains that with this being the bomb's first use, it showed a "ethical standard common to barbarians from the Dark Ages". The bomb was used in a city, leading to the deaths of countless women and children, and not the deaths of countless troops. Document F shows the meaninglessness of the bomb, and what it actually
Atomic Bomb DBQ - Ben Fernandez Imagine waking up and getting ready for the day. Go walking on the way to work and a plane goes overhead. Looking up and see a small thing attached to a parachute get dropped from the plane. All the sudden the sky erupted in flames.
“The second stage explosion is due to nuclear fusion in the central column. The main fusion reaction involves concentrated deuterium and tritium (both heavy isotopes of hydrogen) -- which become spontaneously available when neutrons from the first stage explosion bombard a solid material called "lithium deuteride" located in the central column. When this hydrogen-rich mix is heated to 100 million degrees, the deuterium and tritium atoms "fuse" together, releasing enormous amounts of energy. This is the "H" or "thermonuclear" part of the bomb (ccnr) (Howard Morland)”.”
On August 6, 1945 the Enola Gay dropped the 9,700 pound atomic bomb on Hiroshima, Japan. The effects of "Little Boy" and "Fat Man" are controversial as to whether the bombs were necessary. ”Little Boy” housed the isotope Uranium-235 and “Fat Man” housed Plutonium-239. These elements went through nuclear fission in which the nucleus of an atom is broken into smaller pieces or split. During the end of World War II Japan was out of control.
The temperature of the bomb at ground level reached 7,000 degrees Fahrenheit in less than a second. It vaporized people
The dropping of the atomic bomb on Hiroshima occurred on August 6th, 1945 at 8:15 AM. The bomb was a uranium gun-type bomb nicknamed ‘Little Boy’. The amount of energy that the ‘Little Boy’ generated when it exploded was equivalent to a 15 kiloton TNT explosion. However, when the bomb was dropped on Hiroshima, 60,000-80,000 people were killed instantly. Over the next four months, tens of thousands more people died due to various illnesses which were mainly caused by radiation exposure.
1. Immediate Aftermath On August 6, 1945, at 8:15 a.m., an atomic bomb by the name of “Little Boy” detonated 1,900 feet above the city of Hiroshima. The bomb exploded directly above the Shima Surgical Clinic with the force of about 16 kilotons of TNT, causing the burst temperature to exceed 1 million degrees Celsius and creating a massive fireball measuring 840 feet in diameter. The explosion killed an estimated 70,000 to 80,000 and injured a similar number.
Inside was a naval gun containing two uranium-235 particles that could be fired together to form the ‘supercritical mass’4, which triggers the atomic explosion. When the bomb detonated, Fireballs, Shock Waves & Air blasts and Radioactivity were the three destructive energy sources formed. Due to air absorbing heat, the fireball swells to an approximate 410m diameter with a temperature of 300,000 oC. The bright orange glow that creates the initial mushroom cloud shape was the fireball and it’s emitted thermal rays causing the ‘temperature on the ground near the centre to reach 3000 - 4000 oC’5. 50% of the energy was the shock wave which travelled 11km in all directions, destroying the city and transferring radiation across the city.
It was a fourteen kiloton bomb. It generated enough explosive power to equal 15,000 sticks of dynamite. This bomb was dropped on Hiroshima on August 6, 1945 by Colonel Paul Tibbets pilot of the B-29 sky fortress “Enola Gay”. They were ordered to drop a bomb on Hiroshima but they were unaware of the type of bomb they were carrying. The crew of the Enola Gay recalled the explosion of the bomb as “sitting on a metal trash can and somebody hitting it with a baseball bat.”
The bomb weighed 10,800 pounds and was 10 foot 8 inches long. The fuel was enriched plutonium 239. The core was surrounded with 5,300 pounds of explosives and the core of plutonium was made to be the size of a tennis
The bomb had an explosive power of 20,000 tons of tnt. It was the most explosive bomb
The way the bomb is detonated is that you need fissionable material that will collide together. Inside the bomb, down a long tube, a piece of uranium (or plutonium that was used later in bombs after the little boy) was shot at another
The brutal climax of World War II was something that the world can never forget. On August 6, 1945, an American B-29 bomber dropped the world’s first atomic bomb ever produced, code-named “Little Boy”, containing 64 kilograms of uranium-235 over the Japanese city of Hiroshima. The bomb exploded 600 metres over the city and created a blast equivalent to about 15 kilotons of TNT. The explosion vapourized 80,000 people instantly and destroyed 90 percent of Hiroshima. Three days later, another American B-29 bomber dropped a second bomb, code-named “Fat Man”, containing just over six kilograms of plutonium-239.
