Why does a bullet fire if you strike the point hard enough? E.G. Inside a revolver, the six-chamber holder is rotated as you push a trigger, and a spring loaded hammer strikes the back of the bullet casing forcefully, causing the gunpowder to ignite, propelling the actual bullet into the poor victim.
Kenetic energy, unless friction is applied, does not equal heat. Thus, why does the gunpowder ignite?
Comment some answers. It's been buggin' me.
AHAHAHAHAH YOU SKIPPED OCTOBER 30TH.
ReplyDeleteUPDATED DAILY FAILZ. >:D
I so didnt. pay attention to the post times >:|.
ReplyDeleteA gun launches a projectile at high velocity using the force of expanding gas. If the gas comes from burning a propellant it is a firearm, otherwise see the information on airguns.
ReplyDeleteContrary to popular opinion, the process that propels the projectile is not an explosion, but rather a very fast burn that releases hot gas. Black powder is only explosive under certain conditions and smokeless powder is not an explosive at all.
A most basic gun consists of a barrel closed at one end and an ignition system of some sort. Earliest guns were matchlocks. They used a slow match - a smoldering piece of string. Then came flintlocks which produced sparks from flint striking steel, later to be replaced by percussion caps which used a small amount of chemical that ignited on impact from a spring-loaded hammer. The percussion caps then evolved into cartridge primers that use the same principle. Matchlocks and flintlocks also required the use of a small amount of very fast burning and easy to ignite powder called a priming charge to set off the main charge inside the barrel.
Modern guns use either a combination of a hammer and firing pin or a striker. The hammer or the striker are spring-loaded and held back by the sear. Pulling the trigger moves the sear out of the way allowing the hammer to fall on the firing pin or the striker to move forward and to smash the primer of a cartridge which produces a flame to ignite the propellant charge inside the the cartridge case. The burning powder produces gas, which rapidly expands. The pressure from the gas expands the casing slightly making it seal the breech and pushes the projectile out of the case and down the barrel. In an auto loading firearm some of this gas may be diverted to operate the action.
Aweesome. :D
