Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, ...
Recoil: The backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile, according to Newton's third law. (often called kickback or simply kick). Recoil operation: An operating mechanism used in locked-breech, autoloading firearms. As the name implies ...
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes. It is about 40,000 km (25,000 mi) long [ 1 ] and up to about 500 km (310 mi) wide, [ 2 ] and surrounds most of the Pacific Ocean .
In non-recoil-operated firearms, it is generally the entire firearm that recoils. However, in recoil-operated firearms, only a portion of the firearm recoils while inertia holds another portion motionless relative to a mass such as the ground, a ship's gun mount, or a human holding the firearm. The moving and the motionless masses are coupled ...
Howitzer cartridges, both BL and separate QF, contained a central core of cordite surrounded by several stacked ring-shaped bags of cordite. To obtain the appropriate "charge" for the required range and angle of elevation, the gunner discarded one or more rings before loading. See charge for how Ordnance QF 25-pounder charges varied in World ...
The appearance of the shining swords of the two knights and the extended hand of the saintly personage made them recoil and vanish in sulphurous explosions. The battle lasted for a long time. New demons succeeded the others however; the victory remained with the personages in the boat, who were taken back to the landing of the Piazzetta. The ...
The C/72 was a typical built-up gun constructed of steel with a central rifled tube, reinforcing layers of hoops, and trunnions.The C/72 featured a new breech which although similar to the breech of the C/64 had a semi-circular face which allowed the gun to avoid the stress fractures which caused catastrophic failures in its square blocked predecessor.
For handgun cartridges, with heavy bullets and light powder charges (a 9×19mm, for example, might use 5 grains (320 mg) of powder, and a 115 grains (7.5 g) bullet), the powder recoil is not a significant force; for a rifle cartridge (a .22-250 Remington, using 40 grains (2.6 g) of powder and a 40 grains (2.6 g) bullet), the powder can be the ...
