In diamond, all the carbon-to-carbon bonds, both within a layer of rings and between them, are in the staggered conformation, thus causing all four cubic-diagonal directions to be equivalent; whereas in lonsdaleite the bonds between layers are in the eclipsed conformation, which defines the axis of hexagonal symmetry.
Prince Rupert's drops have remained a scientific curiosity for nearly 400 years due to two unusual mechanical properties: [4] when the tail is snipped, the drop disintegrates explosively into powder, whereas the bulbous head can withstand compressive forces of up to 664,300 newtons (67,740 kg f).
The value of brisance depends on the application. At one extreme, if an explosive is to be used for propulsion, e.g. by driving a piston or a bullet, brisance is likely to be undesirable, because the objective will be to move the load, not to shatter it or the engine or
machine gun anti aircraft training ammunition. The L.S. L'spur bullet weighed 6 grams (93 gr) and was basically the same as used in the L.S. ammunition but combined with a tracer that added 0.5 grams (7.7 gr) extra weight. This cartridge can be recognized by the green stripe over the case head and a black bullet tip.
A 4-year-old accidentally knocked over and shattered a 3,500-year-old Bronze Age jar during a visit to the Hecht Museum at the University of Haifa in Israel on Friday.. The museum said the ...
They can be used to generate mechanical force to shatter or propel various materials; and for pyrotechnic effects for film and live theatrics. [2] A squib generally consists of a small tube filled with an explosive substance, with a detonator running through the length of its core, similar to a stick of dynamite.
Goldberg said that if people had been shown the autopsy photos of the kids, the gun debate would have been transformed. “The fact that not a single one of those kids was able to be transported to a hospital, tells me that they were not just dead, but really really really really dead. Ten-year-old kids, riddled with bullets, dead as doornails.”
