A Catapult is a device that is used to launch an object. These devices are very ancient and have been used in many areas, mostly in Europe during the middle ages. Catapults were highly used weapons. The first Catapult was meant to replace a crossbow, by increasing the range and power. Diodorus Siculus was a Greek historian, he was the first to actually document a catapult in action. Catapults were used to launch missiles at walls and also over walls to create extreme damage to the population. They would also launch diseased bodies over walls to infect the population as well. There are 3 different types of Catapults, Ballista, Mangonel, and Trebuchet. Ballista comes from "Ballistes" which is a Greek word meaning throw. The Ballista was the earliest catapult to be invented. It is very similar appearance to a crossbow but much larger. Ballista was made with two wood planks that is attached to a piece of rope. The rope was then attached to a winch. …show more content…
Mangonel comes from "Manganon" which is a Latin word for “engine of war.” The Mangonel was an invention from 400 BC by the Romans. The Mangonel is made with a long wooden plank used as an arm with a bucket, along with a rope attached to the end. They used this device by pulling back the wooden plank at a 90-degree angle. When released the plank would go back to its “equilibrium position,” when it hits with the beam the plank would stop but the object that was inside the bucket would remain in the air and hit the target. The Mangonel has accomplished to fire an object to the height of 1,300
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)
The population of the whooping cranes most definitely gets affected from precipitation, because the population gets affected negatively with high precipitation levels present, while positively with low precipitation levels. The population of the whooping cranes gets affected this way because if there were high precipitation levels for a year, the hatching success rate drastically decreases from the precipitation, who damages the eggs laid by the cranes. By either breaking the eggs, making the cranes not be present to incubate their eggs, or actually destroying the birds’ nests. Also, the high precipitation levels may even cause a few fatalities, which is a very serious problem involving this particular endangered species. While with low precipitation
First the energy of conservation. The setting of the trebuchet before firing is shown in Fig 1. A heavy counterweight of mass (M) (contained in a large bucket) on the end of the short arm of a sturdy beam was raised to some height while a smaller mass (m) (the projectile), was positioned on the end of the longer arm near or on the ground. In practice the projectile was usually placed in a leather sling attached to the end of the longer arm. However for simplicity, we shall ignore the sling and compensate for this omission by increasing the assumed length of the beam on the projectile’s side. The counterweight was then allowed to fall so that the longer arm swung upward, the sling following, and the projectile was ultimately thrown from its container at some point near the top of the arc. The far end of the sling was attached to the arm by a rope in such a way that the release occurred at a launching angle near the optimum value ( most likely by repeated trials) for the launch height. The launching position is shown in fig.2 where we have assumed that the projectile is released at the moment the entire beam is vertical. In the figures: (a)=height of the pivot, (b)= length of the short arm, (c)= length of the long arm, while (v) and (V) are the velocities of (m) and (M), respectively, at the moment of launching.
The U. S. Soldiers used the M-79 40mm, also known as the thumper, which looked like a sawed shotgun. It could fire up to 300 meters and fire a 6.5 pound grenade. The M-72 is a BBMM light anti-tank weapon that weighs 5.2 pounds. It was also used as a bunker buster and fired a 1 kg rocket that could travel 300 meters. (173dairborne)”
Another type of catapult is the Onager. Onagers were used right up to the middle ages with the Trebuchet, when gunpowder and the Cannon were invented and eventually replaced the catapults.
For almost as long as civilizations began they have been fighting against each other. Often times these wars come down to who has the better military equipment. When one army creates an elite war machine another army is sure to soon copy or improve it. For example the U.S. Army Signal Corps purchased the first ever military aircraft in 1902 (Taylor). Two years later the Italians were also using aircrafts. The trebuchet catapult is no exception; it was one of the most destructive military machines of its time (Chevedden, 2000). A trebuchet works by using the energy of a falling counterweight to launch a projectile (Trebuchet). In this research paper I intend to explain the history and dynamics of a trebuchet catapult.
Used by castle commanders during times of peace to hurl roses to ladies during tournaments, trebuchets proved a deadly weapon in the field of ancient warfare. Flinging a wide variety of objects hundreds of yards, the trebuchet became the weapon of choice for laying siege to a castle. Its incredible range could often place it beyond the effectual defense range of the castle archers, thereby permitting the besiegers to destroy the defender's walls with little interference. During extended sieges, trebuchets were often used to hurl large quantities of dung, dead animals, and other such items to encourage disease throughout the besieged city.
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.
Catapults have been traced back to many different civilizations throughout history, but its modern origins are usually attributed to the Greeks and the ancient scientist Archimedes who designed them (Paul 58). We know that in 339 A.D. Dionysius ordered their design in Syracus (Hansen), but their history goes back even further. The first recorded description of the catapult found in the Bible 2,800 years ago (Paul 58). One passage gives the following description of a ruler of the kingdom of Judah :
The history of catapult spans far from ancient time, until modern times with the basic principles remained the same. the designs became more complicated, but the intent is the same (shooting an object, such as rocks, into the air).
A trebuchet is a type of catapult, which is a common type of medieval weapon that uses a swinging arm to throw some sort of projectile. Trebuchets first appeared in Ancient China during the 4th century BC as a long attack weapon. It spread west and was adopted by the Byzantines in the mid 6th century AD. It uses manpower to swing the arm to launch a projectile. The later counterweight trebuchet, also known as the counterpoise trebuchet, uses a counterweight to swing the arm. It appeared in both Christian and Muslim areas around the Mediterranean in the 12th century, and made its way back to China from Mongols in the 13th century.
“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 weapons were used in the European warfare. There was a weapon that could cause havoc and destruction. The Onager Catapult would throw the big rocks into the castle to break the stuff inside. They even sometimes used missiles. Castles and fortified walled cities were common during this period, and catapults were used as siege weapons against them. The Viking siege of Paris in 856 A.D saw the employment by both sides of virtually every siege craft known to the classical world. There were a variety of catapults to little effect
Because of their effectiveness in terms of distance, accuracy, control, camouflage, and sustainability, they will affect artillery to change its doctrine and weapons. On 13 May 1972, a month after the first unsuccessful attack on the Thanh Hóa Bridge ("Dragon's Jaw"), initial versions of HPW were successfully applied to destroy a bridge that could not be destroyed before and consumed 800 sorties of US forces (https://en.wikipedia.org/wiki/Precision-guided_munition). The accuracy that HPW brought to us forces in that fight caught attention of military authorities to make its use more extensive. Later, they were used by the British forces during the 1982 Falklands War (https://en.wikipedia.org/wiki/Precision-guided_munition). Instead of carrying heavy artillery weapons together with units, the British used HPWs from the deck of the ships, located far from island, to destroy the targets inside the island. During these two applications of HPW, both US and British forces had identified lesson from experience that fire support can be more accurate, economic, and easy to handle if they make changes in artillery doctrine and organization to allow exploitation of HPW. After having this idea, both countries set about exploitation of HPW widely. Another example of the application of HPW can be Russia’s recent employment of rockets from the Caspian Sea into Syria to destroy targets in areas controlled
