Catapults Research Paper

The earliest trebuchets were ‘traction trebuchets’, which were developed in China in the 4th Century B.C.E. Traction trebuchets used human labor instead of a counterweight for power. The Chinese needed so much power for the trebuchet that they had up to 250 soldiers pulling on ropes to operate the machine. This machine could throw stones up to 100 meters, but was not very accurate, because of the inconsistency in using manpower.

Fourth the ancient trebuchet King Warwolf. Finally the end of an era. The materials used to build the medieval trebuchets. The early trebuchets were made of straight, heavy oak logs.

The first cannon was found in Sweden and was dated back to 1326. It was used at the battle of Crecy in 1346. Cannons changed the tide of the war. They could take down ships blow up groups of people and you could stuff screws and nails in the cannon and fire it called grape shot. The first step to load a cannon is you take the worm (sacrapos) and Coleman the barrel. The second step is to use the Ladle (Cuchara) and lightly dip it in the waste and stick it down the barrel, to make sure all the sparks are out. The third step is to put the cannon gal, i. With a bag of gunpowder and use the rammer (Atacador) to pack them in the cannon. The fourth step is to use the Vent Pick to break the bag of gunpowder. The fifth step is to step back and light the

Trebuchets are most commonly known as medieval weapons used in the Middle Ages. Us three were to build a smaller scale of the trebuchet and had to make sure it hit the target two out of the five times. We had to build a hinged-counter weight type of trebuchet with wheels that could throw a ping pong or golf ball. Through the paper I will explain the history throughout trebuchets and why to have wheels and to have a hinged counter weight on the trebuchet. Also the calculations on the potential energy and velocity are through this report. Our trebuchet met all of the requirements that were to be made and it hit the target three out of the five times. This report will

Staring at the map and planning his next course of action, Nightburn had called a meeting of all his high-ranking officers, Sir Faine, Lady Sara, General Zhousbek, Ject, Ace, his assassination squad and personal bodyguards. His officers trailed into the room over the next few minutes with a group gathered near the door engaged in idle conversation, but all grew quiet when Nightburn directed his question to Ject. “Is everyone here?”

Throughout human history, we have tried to create original designs for weapons, which attack an enemy from a great distance. One of the most successful of these weapons was the catapult. Yet, many steps were taken before the catapult was created. First, the sling was produced to surmount the restrictions of the weak human arm. Next, hunters and soldiers invented the bow and arrow to advance in aim and velocity. Eventually, key advances in power and accuracy were achieved with the design of the catapult. The catapult was first invented around 400 BC by the Greeks. In fact it was the Greeks and Romans who first perfected the use of this weapon. After much improvement their catapults were able to throw sixty-pound rocks five football fields

The way a Trebuchet works is that a counter weight drops which pulls the arm forward and at the point of takeoff a pin releases the object that is being projected. The counterweight drops using gravity and is attached to the arm causing it to fly up and launch the object. Engineers have had previous experience in this field because of the world wide trebuchet launching competitions. One example of engineers making this trebuchet are the engineers from team NASAW in the Pumpkin Chunkin ' competition. Team NASAW has a trebuchet with a heavy weight and a long arm. There arm and weight start next to each other at the beginning. The weight drops forward and like a whip the arm swings around and fires the pumpkin into the air at insane speeds. They are one of the top competitors in the competition and have proven countless times that the design works wonderfully.

With the discovery of gunpowder came the invention of the fire arrow with gunpowder on its tip in the year 989 A.D. (Movement of gunpowder). By the 11th century, explosive bombs filled with gunpowder and fired catapults were introduced and used in China (Gun and gunpowder). Approximately eleven years after the arrow, the Chinese invented the flamethrower (Movement of gunpowder). It soon spread across Europe through trading. Ottoman turks used gunpowder to make their own cannons (Whipps).

Compared to the trebuchet, the designs of other siege weapons were lacking in many respects. The most important of these other siege engines included the Greek ballista, the catapult, and variations on the catapult design, such as the Roman onager and mangonel. The ballista's design was very similar to an extremely large crossbow with a guide chute to keep the projectile on path. A large ballista could launch an eight pound stone over 450 yards. It took two men to operate a ballista (Hamper). A standard catapult used the inconsistent strength and weight of men as a source of power. Groups of men had to work to pull down the catapult bar in order to launch the objects. Such catapults could typically throw as much as a fifty pound rock. An onager was type of a catapult with a short arm that would be launched forward by many twisted sinews. Both the onager and the ballista were limited in accuracy and range, because the tightly twisted sinews and ropes continually wore out and needed to be replaced. Likewise, the standard catapult lacked accuracy because of the inconsistent strength and weight of the men who fired it. While all of these siege machines were useful, none of them had the range, or were as powerful, accurate, and widely used as the trebuchet (Gurstelle 18-22).

Have you ever wondered how they would break down castle walls in the middle ages or about middle age warfare in all. I am going to build a trebuchet to learn more about Newtons Laws of Motion and how these simple yet complex machines ruled the battlefields in the middle ages. I became interested in this topic because I am fascinated by middle aged weaponry and machines. This will be beneficial to my knowledge to help me understand Newtons Laws of Motion and about these giant machines. I believe that learning more about Newtons Laws of Motion may help to explain why different designs affect the trebuchets range and power.

Catapults vary much in size and design. Often times, the procedure in siege battles was to build a catapult for the right situation; the strength of the catapult depended on its’ size and ammunition and how useful it was in the right situation. According to the Google Sites page “Physics of Catapults 101”, “Catapults were known for throwing a multitude of objects at the enemy. These include but were not limited to: stones, sharp wood poles, darts, pots of Greek Fire, quicklime, burning tar, burning sand, dung, dead animals, body parts, and diseased bodies.” (First form of biological warfare utilized the Trebuchet.) Differing catapults fired better suited

Trebuchets were a big way of fighting in the 12th century. They got the kind of weapons they used right, they just did

They made the Battle Axe by a knot in a root or branch with a convenient to make a good battle axe. also would put frog poison on the darts and put them in the blowgun. Stone weapons, tomahawks and battle hammers were made from rocks of the correct overall shape by sharpening one edge and grinding a binding groove around the stone using other, harder stones.

The history of weapons started centuries ago when cave people initially developed a weapon called a bow and arrow, for hunting purposes. They created this weapon from yew or elm for the bow and the arrow’s shaft, and used animal ligaments, or sinew to add tension to the bow. Archeologists have also found arrow heads made of sharp rocks and angled bones from different types of animals. These artifacts are all over the world displayed beautifully in museums to make new civilization realize the important role weapons have played in daily life.

The discovery of gunpowder was discovered in 850 A.D. by accident. Gunpowder also called black powder is considered the earliest explosive invented. The Chinese alchemists of the ninth century were considered to be a major force behind the early development of gunpowder. They first used the substance to treat skin diseases and to kill insects before people realized it would be
