You suck. You’re gonna kill this guy. You call yourself a good trauma surgeon. You’re the worst. And you just plow ahead and plow ahead and plow ahead. You find what’s injured. You control it. God. Oh, you are the best. You’ve done a great job. Then you’re working. You find another injury you didn’t expect. You suck, you suck, you ...
Hydrostatic shock, also known as Hydro-shock, is the controversial concept that a penetrating projectile (such as a bullet) can produce a pressure wave that causes "remote neural damage", "subtle damage in neural tissues" and "rapid effects" in living targets.
Hard cast solid bullet (left), with gas check (center) and lubrication (right) A modern centerfire cartridge consisting of the following: 1. bullet, as the projectile; 2. metallic case, which holds all parts together; 3. propellant, for example gunpowder or cordite;4. rim, which provides the extractor on the firearm a place to grip the case to ...
Probability of bullet penetration increases as the axis of bullet movement becomes perpendicular to the target surface; but penetration may create a depression or crater within which the bullet may ricochet more than once, possibly following the arc of the crater floor to depart the crater at a greater angle from the original surface than the ...
Children are less likely to survive AR-15 wounds. The leading cause of death in children between the ages of 1 and 19 in the U.S. is gun violence, according to a recent New England Journal of ...
The bullet must tightly fit the bore to seal the high pressure of the burning gunpowder. This tight fit results in a large frictional force. The friction of the bullet in the bore does have a slight impact on the final velocity, but that is generally not much of a concern. Of greater concern is the heat that is generated due to the friction.
Handgun propellants may reach peak pressure before the bullet leaves the cartridge case, while rifle propellants may move a bullet several inches before reaching peak pressure. [ 4 ] : 125 The motion and behavior characteristics of projectiles while under the influence of the gases produced by the propellant is known as internal ballistics .
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
