The light-gas gun is an apparatus for physics experiments. It is a highly specialized gun designed to generate extremely high velocities. It is usually used to study high-speed impact phenomena ( hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids.
A 1/2" drive pistol-grip air impact wrench. An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft ...
Hand cannon from the Yuan Dynasty (1271-1368). The history of firearms begins in 10th-century China, when tubes containing gunpowder and pellet projectiles were mounted on spears to make portable fire lances, [1] operable by one person. This was later used effectively as a shock weapon in the Siege of De'an in 1132.
Physics of firearms. From the viewpoint of physics ( dynamics, to be exact), a firearm, as for most weapons, is a system for delivering maximum destructive energy to the target with minimum delivery of energy on the shooter. [citation needed] The momentum delivered to the target, however, cannot be any more than that (due to recoil) on the shooter.
Test firing at the United States Naval Surface Warfare Center Dahlgren Division in January 2008 [1] [clarification needed] A railgun or rail gun is a linear motor device, typically designed as a weapon, that uses electromagnetic force to launch high- velocity projectiles. The projectile normally does not contain explosives, instead relying on ...
The Public Safety and Recreational Firearms Use Protection Act, popularly known as the Federal Assault Weapons Ban (AWB or FAWB), was a subsection of the Violent Crime Control and Law Enforcement Act of 1994, a United States federal law which included a prohibition on the manufacture for civilian use of certain semi-automatic firearms that were defined as assault weapons as well as certain ...
The cannon was capable of firing proto-shells, cast-iron bombs filled with gunpowder. [1] Gunpowder artillery in the Middle Ages primarily consisted of the introduction of the cannon, large tubular firearms designed to fire a heavy projectile over a long distance. Guns, bombs, rockets and cannons were first invented in China during the Han and ...
Battle rifle: A service rifle capable of semi-automatic or fully automatic fire of a full-power rifle cartridge. Bayonet lug: An attachment point at the muzzle end of a long gun for a bayonet. Belt: An ammunition belt is a device used to retain and feed cartridges into some machine guns in place of a magazine.
