Using Physics to Design a Riffle

A firearm is one of the weapons that may be used when hunting. A firearm utilizes pressure produced from the burning of gunpowder to create gas. The pressure produced from the burning powder propels a projectile out of the barrel at a target. In rifles and most handguns the barrel has rifling on the inside of the barrel to make the projectile spin to travel better in the air. Rifling are groove that spin as they go through the inside of the barrel. Shotgun barrels are smooth and can fire “slugs”, a single projectile, or “shot”,

Historically great feats of engineering have been the tell-tale sign of a great civilization. The Great Wall Of China, The Roman Aqueducts, and buildings that reach for the skies. Today Aerospace engineers propel us out of our world and to new and even higher heights. The evolution of engineers comes from a cornerstone of their method, The Engineering Method. They research, prototype and improve their design until they find a solution that fits. Engineers are constantly improving their work so that they can push the boundaries of what we believe is possible. Engineers communicate their progress in science and engineering through their amazing feats and groundbreaking

A bullet is traveling at its fastest speed when it leaves the barrel of the gun. Bullets traveling after firing is said to be using kinetic energy. Kinetic energy is the energy the bullet has due to its motion from the firing pin striking the gun powder causing an explosion that forced the bullet to discharge from the barrel. Now this bullet possess kinetic energy and will do harm

To understand the gun topic you first have to learn the terms a pistol, or hand gun is a gun that the name states you use the gun held in your hand normally used for close range. A revolver is a hand gun that instead of the ammo being fed into the chamber, it is in a round shaped tube with different chambers that rotate in a clockwise motion around the barrel of the gun. A shotgun can either be semi-automatic, where you have to pull the trigger every time you shoot. Pump action, where you have to pull the trigger pump the action on the gun to chamber another shell. The last is not legal to most citizens, but a fully automatic weapon once you pull the trigger as long as you hold down the trigger it will fire till your run out of ammo. Shot guns shoot shot or gauges that are little bb’s or ball bearings. Rifles come in all different makes, models, and sizes. From lever action where you have to cock a lever to chamber a round, to bolt actin where you have to pull back a bolt to chamber the next round, to semi auto and full auto. These guns are for long range and are meant to give the ability to reach out and touch an object. Machine or submachine guns can be used in semi-automatic, three round burst, or full auto. No matter how big or small all guns are either

A Rifle could shoot a bullet up to 1,000 yards–and were more accurate. However, until the 1850s it was nearly impossible to use these guns in battle because, since a rifle’s bullet had roughly the same diameter as its barrel, they took too long to load. (Soldiers sometimes had to pound the bullet into the barrel with a mallet.)

In wars prior to the Civil War, soldiers wielded weapons such as the musket which shot only one bullet at a time. Though these types of weaponry could shoot as far as 250 yards, they were inconvenient and wasted time. To even aim at the target accurately one had to be 80 yards away. Similarly to muskets, rifles were inconvenient because they took a while to reload because the bullet was almost the same size of the barrel and again, wasted time. Bullets with a pointed tip were created in 1848 by Claude Minie. Because the diameter of the bullets were smaller than the barrel, soldiers could put them into the gun quicker and more effectively. With Minie’s bullets, rifles were simpler to reload but still had to be reloaded with one bullet at a time. That unprotected gap of time made soldiers more vulnerable so in 1849 a repeating rifle called the Volitional Repeater was patented by Walter Hunt. They were popularized in 1863 during the Civil War. By this time many models were being sold but the most common one was the Spencer Carbine which could shoot seven bullets in just 30 seconds. These, like most Civil War era weapons, were produced and used by the North, but not

When the constitution was written the most advanced gun only shot one bolt at a time, and took 30 seconds to reload (Murphy). Now in the 21th century guns have “high-capacity magazines were used in at least 50% of the 62 mass shootings between 1982 and 2012. When high-capacity magazines were used in mass shootings, the death rate rose 63% and the injury rate rose 156%. David H. Chipman...stated that a high-capacity magazine ‘turns a killer into a killing machine.’ Some gang members use high-capacity magazines, such as 30 rounds or even 90 rounds, to compensate for lack of accuracy and maximize the chance to harm” (“Background of the Issue - Gun

A firearm is a very complex tool that has grown in s verbal ways over several years, each version better than the last, all of which changing the world in a new way.All across the world and across several eras firearms have been used, firearms have also been the reason for wars and laws, as a very important part of our history it is appropriate that several facts are clearly stated.Back in the Han dynasty, under the leadership of emperor Wu Di, gunpowder was discovered. This particular document will include such topics such as the one previously stated and early firing systems and other weapons, also a brief history of military issued pistols through America's history and your rights as an american citizen to bear arms. Firearms, from early

There is no reason for an ordinary citizen to buy a high-capacity firearm. These high capacity weapons are used for mass killings. As reported in Everytown for Gun Safety, high-capacity firearms were used in 50% of about 62 mass shootings between 1982 and 2012. The death rate rose 63% and the injury rate rose 156% when a high-capacity firearm magazine was used. A high-capacity firearm is a firearm that can hold a lot of ammunition. The Washington Post reported a man armed with an assault-style rifle killed at least 50 people and wounded 53 others in a nightclub in Orlando. In San Bernardino, CA, a man and woman used assault-style rifles to kill 14 people at a holiday party. In 2012 in Newtown, C., a man with an assault-style rifle killed 28 people at an elementary school.

Another very powerful gun that was used in World War II was the Submarine guns. The submarine guns are much stronger and better than normal guns due to the fact that they have better firing distances (Military History 7). The submarine gun was built mainly for endurance and for accuracy. This gun had the accuracy to fire from 800 to at least 1,000 yards away and delivers a powerful blow to its victims. One problem which the gun had was the fact that it could dislocate a soldiers arm whenever it was fired. But finally the submarine gun was improved and is now less powerful which makes it easier for firing full automatic rounds along with pistol rounds (8).

Weaponry plays a very large role in the war. While the soldiers were on their last legs, the nation decided to set foot and make a decision to improve the industry. The most common problem faced by all soldiers was the loading of guns. Soldiers typically carried guns that held one bullet at a time. A soldier who was trying to aim and shoot the target would have to stand much closer, as the weapon’s range was only about 80 yards. Hence, battles were fought relatively at a closer range. Rifles, were used for long range shooting, and were very accurate as the bullet could travel up to 1,000 yards. However, it was impossible to use the guns in battle since it took a very long time to load. Fed up with the trouble caused with the guns, Captain Henri Gustave Delvigne and Claude Etienee Minnie developed a cone shaped lead bullet called, “Minnie Balls”. When fired, the bullet expanded, and the lead would grip tightly against spiraled rifling groves. This would take a spin on the elongated bullet, leaving the muzzle at a higher velocity and following an accurate trajectory causing it to travel three-four times farther. The innovation of the rifle and Minnie Ball were just a few of the hundreds of weaponry inventions. Weapons fell under three categories—small arms, artillery, and edged weapons. These were developed after the society wanted to see a difference in the nation. They were placed under these categories based on their caliber (size of the

Unlike muskets the newer, better weapons had the capacity of multiple rounds like revolvers could shoot 4 to 6 shots before reloading allowing multiple opportunities

This repeating lever action rifle was the start of a new generation of guns. This rifle was the precursor to the Winchester rifle of 1866 and gave speed firing a whole new meaning. This gun lead into what we now know about rifles, from the AK-47 to the regular Winchester .22 hunting rifle. This gun changed so much more than the ability to shoot faster, it was easier to load, had an extremely accurate shot and was considerably easier to handle, especially while moving (this is why this type of gun was so popular with soldiers on horseback and or moving train). The Winchester of 1866 and the Henry rifle was the start of a new beginning, and this lead into many other opportunities that helped shape our nation even more, it helped conquer the west and defend this

Made in the 1860s, the rifle could shoot almost double what the musket could. The rifle could be reloaded twice as fast. But there still was a problem the bullet would wigel because the bullet would hit the side of the barle.

Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed, the eye and how eye glasses help a person see better, speakers, the Frisbee, sailing, and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods.
