Filling weight. 18,739 lb (8,500 kg) Blast yield. 11 tons TNT (46 GJ) The GBU-43/B Massive Ordnance Air Blast (MOAB, / ˈmoʊæb /, colloquially explained as " mother of all bombs ") is a large-yield bomb, developed for the United States military by Albert L. Weimorts, Jr. of the Air Force Research Laboratory. [1] It was first tested in 2003.
Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) [1] is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials, the ultimate tensile strength is close to the yield point, whereas in ductile materials, the ultimate tensile strength ...
White Army, Black Baron. " The Red Army Is the Strongest ", [a] popularly known by its incipit " White Army, Black Baron ", [b] is a Soviet march song written by Pavel Gorinshtein [ru] and composed by Samuel Pokrass. Written in 1920, during the Russian Civil War, the song was meant as a combat anthem for the Red Army.
F5. 261–318 mph. Incredible. The Fujita scale (F-Scale; / fuˈdʒiːtə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or ...
The PHIVOLCS earthquake intensity scale (PEIS; Filipino: Panukat ng Pagyanig ng Lindol) [1] is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) to measure the intensity of earthquakes. It was developed as upon a specific response to the 1990 Luzon earthquake.
This includes a description word for each level of the scale. The Enhanced Fujita scale (abbreviated as EF-Scale) rates tornado intensity based on the severity of the damage they cause. It is used in some countries, including the United States and France. [1] The EF scale is also unofficially used in other countries, including China.
SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field.
