What net external force in N is exerted on a 1350 kg artillery shell fired from a battleship if the shell is accelerated at 3.00 ✕ 104 m/s2 enter the magnitude?
Force = mass × acceleration. Force= 1350 × 2.80× 104 m/s2. Net external Force = 3.8 × 107 N.
What causes an artillery shell to explode?
Modern high-explosive artillery shells consist of a shell casing, a propelling charge, and a bursting charge; the propelling charge is ignited by a primer at the base of the shell, and the bursting charge by a fuse in the nose.
What net external force in N is exerted on a 1450 kg artillery shell fired from a battleship if the shell is accelerated at 1.80 ✕ 104 m/s2 enter the magnitude?
Thus, the net external force exerted on artillery is 3.77×107N 3.77 × 10 7 N .
How is artillery so accurate?
Modern artillery consists of increasingly sophisticated and integrated technology platforms. From mortars to howitzers, these GPS-guided systems are designed to deliver pinpoint accuracy at ranges of up to 30 kilometres.
What kind of explosive is used in artillery shells?
The most common shell type is high explosive, commonly referred to simply as HE. They have a strong steel case, a bursting charge, and a fuse. The fuse detonates the bursting charge which shatters the case and scatters hot, sharp case pieces (fragments, splinters) at high velocity.
Can artillery shells destroy a tank?
The new weapon represents an exponential leap beyond existing state-of-the art anti-tank weapons such as the TOW and Javelin missiles; the Javelin reaches ranges up to 2.5miles and the TOW missile can hit targets out to 3,000 meters.
What are the 3 types of artillery?
- Guns – heavy weapons with long barrels to batter fortifications with shot at long range.
- Howitzers – shorter barreled guns with “chambers” in the bores for smaller powder charges.
- Mortars – short chambered pieces used for lobbing shells at great elevation into the fortifications of the enemy.
Is artillery still effective?
This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army’s total firepower.
How do artillery shells work?
In an artillery shell, the driving band or rotating band is a band of soft metal near the shell’s bottom, often made of gilding metal, copper, or lead. When the shell is fired, the pressure of the propellant forces the metal into the rifling of the barrel and forms a seal.
What is the speed of an artillery shell?
The speed of these artillery shells can reach up to speeds of about 1600 m/s or, in English units, about one mile per second.
How is an artillery shell measured?
Ammunition size is usually expressed in terms of calibre, which is the diameter of the projectile as measured in millimetres or inches. In general, projectiles less than 20 mm or . 60 inch in diameter are classified as small-arm, and larger calibres are considered artillery.
Can a 155 mm howitzer destroy a tank?
But yes a direct hit from a 155 round would probably kill an Abrams, especially since the arc or the round will see it go right through the top of the tank. And the tank would be completely destroyed with the entire crew killed most likely. A catastrophic hit.
What happens when an artillery shell explodes?
Most artillery rounds are designed to create some kind of shrapnel when they explode. Shrapnel works kind of like a bullet. It’s a piece of metal flying at high speed through the air, hopefully catching an enemy soldier along its path.
Can a M777 destroy a tank?
The M777 and M109A7 Paladin howitzers will be able to destroy tanks on the move at a distance of 70 km due to the new Ramjet projectile. The U.S. company Boeing and Norwegian Nammo tested a new 155 mm Ramjet projectile for NATO standard artillery.
How accurate is artillery shelling?
The shell is reportedly accurate to within four metres. Another type of guided shell, although not as accurate as the Excalibur, is the M549. The higher accuracy of modern shells has transformed the use of artillery, which previously required heavy logistical support.
Why is artillery called a battery?
Historically the term “battery” referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types.
Why do armies still use artillery?
Artillery also has the added advantage of being cheaper to field and operate than precision-guided air-launched weapons traditionally used by UAS platforms. Gady said that this cost factor makes artillery the more economical option for suppression of enemy fires or for breaking up enemy formations.
How far can artillery shoot?
Modern artillery has also advanced to rapidly deployable wheeled and tracked vehicles and precision delivered munitions capable of striking targets at ranges between 15 and 30 kilometers.
What is an artillery shell made of?
Shell casings have been made from many different materials including brass, steel, aluminum, plastic, and combustible materials. They may also be made from a combination of these materials. Many casing have special finishes on their surfaces to protect them from harsh conditions. Brass casings normally have no finish.
How long is an artillery shell in the air?
It’s about 25-30 seconds for artillery shells, from firing to impact.
What is the difference between shell and bomb?
Bombs differ from artillery shells, missiles, and torpedoes in that the latter are all propelled through the air or water by a man-made agency, while bombs travel to their targets through the force of gravity alone.
Why do longer barrels increase velocity?
Longer barrels give the propellant force more time to work on propelling the bullet. For this reason longer barrels generally provide higher velocities, everything else being equal. As the bullet moves down the bore, however, the propellant’s gas pressure behind it diminishes.
What is the highest velocity bullet?
The . 220 Swift remains the fastest commercial cartridge in the world, with a published velocity of 1,422 m/s (4,665 ft/s) using a 1.9 grams (29 gr) bullet and 2.7 grams (42 gr) of 3031 powder.
Is a bullet faster than sound?
The fastest bullets travel more than 2,600 feet per second. That’s equivalent to over 1,800 miles per hour. To put that in perspective, it’s amazing to realize that bullets travel over twice the speed of sound!
