REVOLVER (firing mechanism and important components)

 REVOLVER

 MAIN PARTS OF REVOLVER

TRIGGER

It is a small lever which is pressed to start the fire mechanism in the gun so that the bullet can be fired

HAMMER

Hammer is the part of fire arm which strikes the firing pin when the trigger is pressed. It passes the mechanical energy from tigger to the firing pin.

FIRING PIN

It is a sharp pointed pin like structure and a spring is wound around it .It impacts the base of the cartridge which contains the propellant.

FIRING PIN

CYLINDER

A cylinder has multiple chambers (6 to 8). It is a rotating part of a revolver. It revolves around a central axis to bring each chamber in alignment with gun barrel.



CYLINDER

GUN BARREL

It is a straight tube through which the bullet shoots off the gun .The inner side of the barrel looks like a spiral shape, it is called rifling .It provides accuracy(by spinning bullet).



GUN BARREL

ANATOMY OF CARTRIDGE

PRIMER

Primer is the base of the cartridge .Firing pin impacts the primer to ignite propellant. 

PROPELLANT

Commonly known as gun powder, propellant is important component of firing mechanism .It ignites giving rise to hot gases firing the bullet.

BULLET

It is a component of firearm ammunition that is expelled from the gun barrel. Bullets are made up of variety of materials such as steel, copper, rubber.



CARTRIDGE

FIRING MECHANISM

When trigger is pressed, hammer acts on firing pin transferring energy from trigger to firing pin.

The pointed firing pin hits the primer (base of cartridge) igniting the propellant.

The propellant burns and expands into hot gases. These hot gases push the bullet into the gun barrel (from chamber)

When bullet passes through the gun barrel it acquires a spin which provides it accuracy.


detailed mechanism

RECOIL FORCE

When the bullet shots off from the gun a recoil force is experienced which can be explained through NEWTON’S third law

EVERY ACTION HAS AN EQUAL AND OPPOSITE REACTION.
