2. Exploded-view drawing - Wikipedia

   en.wikipedia.org/wiki/Exploded-view_drawing

   An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

3. Table of explosive detonation velocities - Wikipedia

   en.wikipedia.org/wiki/Table_of_explosive...

   Contents. Table of explosive detonation velocities. This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive. It is a key, directly measurable indicator of explosive performance, but depends on density which ...

4. Detonation velocity - Wikipedia

   en.wikipedia.org/wiki/Detonation_velocity

   Explosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive. Explosive velocities are always faster than the local speed of sound in the material. If the explosive is confined before detonation, such as in an artillery shell, the force ...

5. Explosives safety - Wikipedia

   en.wikipedia.org/wiki/Explosives_safety

   Quantity-Distance (QD) is the foundation of DOD explosives safety standards. It defines levels of protection from blast based on relationships between the quantity of explosive material (NEW) and distance. The relationships are based on levels of risk considered acceptable for specific exposures but they do not provide absolute safety or ...

6. Gurney equations - Wikipedia

   en.wikipedia.org/wiki/Gurney_equations

   Gurney equations. The Gurney equations are a set of mathematical formulas used in explosives engineering to relate how fast an explosive will accelerate an adjacent layer of metal or other material when the explosive detonates. This determines how fast fragments are released by military explosives, how quickly shaped charge explosives ...

7. Hubble's law - Wikipedia

   en.wikipedia.org/wiki/Hubble's_law

   e. Hubble's law, also known as the Hubble–Lemaître law, [1] is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth.

8. Hydrogen safety - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_safety

   Hydrogen safety. The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704 's highest rating of four on the flammability scale because it is flammable when mixed even in small ...

9. Lead styphnate - Wikipedia

   en.wikipedia.org/wiki/Lead_styphnate

   Lead styphnate (lead 2,4,6- trinitroresorcinate, C 6 HN 3 O 8 Pb ), whose name is derived from styphnic acid, is an explosive used as a component in primer and detonator mixtures for less sensitive secondary explosives. Lead styphnate is only slightly soluble in water and methanol. [3] Samples of lead styphnate vary in color from yellow to gold ...
