Catapults have been a major part of war for many countries for years. They have helped lengthen the firing distance for countries and have therefore allowed soldiers to stay further away from the opposing country. Catapults came about as attempts to put more power and range in crossbows. In 399 BC a Greek historian, Diodorus Siculus, was the first person to document a catapult with an arrow hand, also known as a ballista. The French were the first army to use catapults as a weapon. This happened during the 1216 Siege of Dover. As the war spread through Europe catapults became more needed and the English made there walls higher so the French would use their catapults to either shoot the wall and damage it or hit the people inside the wall. Catapults were used throughout Europe, mainly by the French during 885 – 886 BC until better defence systems were enforced. …show more content…
The ballista gets its name from the Greek word “Ballistes”, which means to throw. The ballista’s design is basically a giant crossbow. It has two wooden arms that are connected to a piece of rope that was usually made of human hair or animal sinew. The rope was attached to a winch that would get pulled back therefore bending the arm. When it was release the ballista would shoot a large arrow or dart towards the enemy. Although the ballista has fantastic aim and hits the target nearly every time it doesn’t have the same power as the trebuchet or mangonel. It was the earliest catapult made. There was also the springald which was a smaller version of the ballista. It was used in more confines places such as castles or towers. It was applied mainly as an antipersonnel weapon. The ballista is believed to be invented by Greeks and modified later by
Question 5: “Texts construct characters who represent the best qualities in human nature, as well as those who represent the worst.” Discuss how at least ONE character is constructed in a text you have read or viewed. (Sem 2, 2016)
CATAPULTS The catapult, was invented by the Romans, and plays a large role in the siege of any castle. Besiegers could fire 100-200 pound stones up to 1,000 feet. The catapult was used to destroy buildings and walls inside and outside of the castle walls, it could also destroy an enemies moral by throwing severed heads of comrades, they could spread disease by throwing shit and dead animals in, and they could destroy wooden building by throwing bundles of fire in.
The ballista was like a much larger version of the crossbow used by besiegers. It got it’s power from being fired with sinew ropes and had two arms. Although the ballista was a great weapon it was hard to construct, therefore the Romans developed a new version called the Mangonel. It, like the Ballista also got it's power from sinew ropes but unlike the ballista which used two arms, the Mangonel only used one arm. To make the Mangonel easier to transport the Romans added wheels. It was very light and could hurl objects such as rocks and even burning projectiles.
According to Chevedden et al., (2002) the Latin word for trebuchet was “ingenium” and those who designed, made and used them were called inginators. These early engineers kept modifying the trebuchet to increase the range and impact force. One of the improvements engineers made was varying the length of the sling ropes so the shot left the machine at a ? angle of 45 degrees to the vertical (shown in the figure above), which produces the longest trajectory (Chevedden et al.,
A popular weapon used by both sides was the rifle. Rifles were invented before the Civil War and were greatly used in the War of 1812. However, more types were built and a larger amount was used during the Civil War. Rifles added a spin to bullets for a greater accuracy at longer ranges. Using this weapon, soldiers could fire 400 yards away, as opposed to the average 80 yards (Robertson 50). Rifles were the fastest and hardest weapon of the time. Rifles allowed their bullets to be shot harder and faster towards its target. New inventions, used by the Union more than the Confederate, included Parrott rifles. They were composed of iron. Robert Parker Parrott, an American soldier and inventor, created these weapons, hence the name Parrott rifles. Despite its name, the Parrott rifle was actually a cannon. Its size ranged from 10 to 300 pounders. It was not favored by most because it was considered unsafe (“Civil War Artillery”). Because of its bulkiness and heaviness, it seldom led soldiers to inaccuratel...
Trebuchets earned a reputation for being much more accurate and precise than their onager and catapult counterparts. Not only was this accuracy a benefit, but being based on rotational motion and leverage rather than torsion (spring power) and lacking in a throwing arm stop, the trebuchet proved a much safer alternative for the personnel operating it. Onagers and Mangonels would literally explode on occasion when the torsion proved too great or a crack developed in the throwing arm due to the rapid stops it experienced.
Before the days of gunpowder, the military used large timber machines to hurl rocks, arrows and flaming barrels of tar at and into castles and forts. In ancient times, in order to prevent attacks from invaders, forts and castles are built for protection. These castles and forts had very strong walls and were sometimes placed high on top of a hill or such. Therefore, people within the military often build machines and structures to aid in attacking castles. These machines were called catapults, which didn’t use explosives like today’s military weapons, instead they used energy which was stored in bent timber and sinew, twisted ropes or heavy weights. A catapult is a machine that initially stores energy and then releases energy in order to fire a projectile. In simple terms, it is a device that is used to hurl an object to a further distance. In order to be classified as a catapult, the machine generally has to be larger than an average person, which logically makes it difficult for the said person to carry. The first catapults were early
Crossbows are a highly effective weapon for hunting and war even in today's standards. The first records of crossbows are from China in the 6th century BC. The knowledge then spreads slowly to the west into Europe during the time of the Roman Empire, the greatest empire of all times. The crossbow remained the favored weapon of war and hunting in Rome until the 15th century when gunpowder was also introduced from China.
...e went into motion. Possible projectiles of the trebuchet were living prisoners, jugs of Greek fire, rocks, and animals. Another large weapon of siege was used primarily in storms, the battering ram. In its early stages, the ram was no more than a hefty beam with a mass of metal attached to the end. Men would hoist the cumbersome boom onto their shoulders and run into a wall or door as many times as needed until the surface under attack gave way. In the Middle Ages, it was developed into more of a machine, for the ram hung from the center of a tent under which the men operating the ram could hide. The ram could be swung like a pendulum much more easily than having to constantly run back and forth. Also, castle guards often poured hot oil or other things onto the ram and its engineers. The tent, which was on wheels, protected the men and the battering ram as well.
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
These engineers that were working for Phillip of Macedonia are trusted with building the first ballista. These model of catapult are used with two wooden arms, hard wound ropes and a cord to assist in the hurling of a deadly rocket, such as spears, at an enemy.
The crossbow was invented in Ancient China during the Zhou dynasty, around the year 700 BC. A Chinese text, from about 200 BC, gives credit to a Mr. Ch'in of Ch'u for inventing the crossbow. It consisted of a horizontally mounted bow, with a stock and trigger mechanism added. The crossbow is derived from the horizontally mounted bow-trap used by other civilizations around the same time. They had a range of up to 650 feet. The crossbow had a firing mechanism, which was so complicated that it would have been nearly impossible for an enemy to understand how it worked, thus reducing the chance that the crossbow could be copied by hostile civilizations.
“Volley Guns” (Chivers, 2010, p.26) or also known as “Organ Guns” (Ellis, 1975, p.10) were first attempts at increasing firepower by adding several barrels at the firing itself, rather than simply attempting to increase the rate of fire. “Gunsmiths had long ago learned to place barrels side by side on frames to create firearms capable of discharging projectiles in rapid succession. These unwieldy devices, or volley guns, were capable in theory of blasting a hole in a line of advancing soldiers” (Chivers, 2010, p.26). An example of such weapons can be seen on July 28, 1835 when Giuseppe Fieshi unleashed terror on King Louis-Phillipe in Paris, France. He fired his 25 barrel “volley gun”, killing 18 of the king's entourage and grazing the King's skull. The weapon was ineffective however. Four of the barrels failed and another four ruptured. Two other barrels had exploded inside, grievously wounding Giuseppe. (Chivers, 2010, p. 27)
The system and technique of supplying an arrow with kinetic energy through the tension of limbs has been improved with the crossbow. The big catapults took up once again the principle of throwing stones. It all changed with the invention of the gunpowder. Cannons, guns and handheld weapons assumed the role of bow and arrow. Now, the warlike intention behind the long-distance effect went even more into the foreground.
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
