Introduction
To understand how machine guns work, it helps to know something ab come on firearms in general. Almost any gun is based on single simple concept: You apply explosive pressure butt a rocket to launch it down a barrel. The earliest, and simplest, masking of this idea is the cannon.
A cannon is just a alloy tube with a unlikable end and an open end. The closed end has a piffling fuse hole. To load the cannon, pulverisation (a mixture of charcoal, sulphur and potassium nitrate) is poured in, and then a round s raging is dropped in. The pulverization and cannonball sit in the breech, the rear expose of bore, which is the open space in the cannon. To prepare the gun for a shot, a fuse (a length of flammable material) is run by dint of the hole, so it reaches down to the gunpowder. To fire the cannon, light the fuse. The flame travels along the fuse, and finally reaches the gunpowder.
When gunpowder is ignited, it burns rapidly, producing a lot of hot gas in the process. The hot gas applies much greater pressure on the powder side of the cannonball than the propagate in the atmosphere applies on the other side. This propels the cannonball out of the gun at high speed.
The first handheld guns were essentially miniature cannons; first load some gunpowder, a stain ball and lit a fuse.
Eventually, this technology gave way to initiation-activated weapons, such as the flint-lock gun and the percussion cap.
Flintlock guns ignited gunpowder by producing a tiny spark, while percussion caps utilise mercuric fulminate, an explosive compound you could ignite with a slap-up blow. To load a percussion cap gun, you poured gunpowder into the breech, stuffed the projectile in on top of it, and placed a mercuric fulminate cap on top of a bitty nipple. To fire the gun, you cocked a hammer all the way back, and pulled the guns trigger. The trigger released the hammer, which swung forward onto the explosive cap. The cap ignited, shooting a small flame down a tube to the gunpowder....If you want to swallow a full essay, order it on our website: Orderessay
