Compressive strength is measured on materials, components, and structures. By definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely. The compressive strength is usually obtained experimentally by means of a compressive test.y definition, the ultimate compressive strength of a material is that value of uniaxial compressive stress reached when the material fails completely.

VX is the deadliest nerve agent ever created. Known by its U.S. Army code name, it is a clear, colorless liquid with the consistency of motor oil. A fraction of a drop of VX, absorbed through the skin, can fatally disrupt the nervous system. Although a cocktail of drugs can serve as an antidote, VX acts so quickly that victims would have to be injected with the antidote almost immediately to have a chance at survival. VX is the only significant nerve agent created since World War II.
Atropine and the additional compounds work best as preventive measures. When administered after exposure to VX or another nerve gas, it will stop the toxic effects, but there will almost certainly be some amount of permanent neurological damage.
