Catapult

In response to the use of castles and fortresses, siege weapons were created. Siege weapons ranged from short range weapons such as the battering ram to longer range ones like the trebuchet or the ballista. The battering ram was usually a big shed with an armored roof and wheels to protect the men inside operating a thick beam with an iron head hung from the roof that was swung into enemy walls to bring them down. The siege tower, a wheeled tower filled with men that would be used to get over the walls, also saw its use during this time. The trebuchet was used for longer range, the missiles launched by the trebuchet ranged from using dead bodies of animals or people to spread disease, a primitive example of biological warfare, to using large boulders to take down fortress walls. In response

To fire it, the spoke or arm was forced down, against the tension of twisted ropes or other springs, by a windlass, and then suddenly released. As the sling swung outwards, one end would release, as with a staff-sling, and the projectile would be hurled forward. The arm would then be caught by a padded beam or bed, when it could be winched back again. The Onager is usually the first type of catapult

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.

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

Another result of technological progression was the matchlock, which would shoot with ignition of a lit match. "The introduction of firearms into the Elizabethan Weapons Arsenal saw the end of castle warfare and the building of the magnificent Medieval castles"(Alchin 1). With the invention of lethal, quick cannons came the decline of forts for defense as soldiers prepared for battle. Cannons were made of bronze and iron, in many different sizes, and they fired stone or iron, to be used on land or

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

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.

Is baseball America's pastime? For the major leaguers maybe, but for college athletes it seems more like a new age video game. The introduction of high dollared aluminum bats produce football like scores, higher statistics, and a percentage of danger to each and every player on the field. The NCAA has changed the regulations of the bats so far and should look further into to making another change to wooden bats.

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

The trebuchet is is believed to be an ancient war engine which was invented in china in 300 A.D it was thought that the medieval may have taken the design from the Stave

The discovery of gunpowder changed war from being fought with medieval weaponry and battle tactics to more modern day weapons and tactics because the gunpowder powered weapons are more deadly. Weapons that use gunpowder to launch projectiles have a greater range than melee weapons and are more powerful than bow and arrows. Also, cannons are more powerful and have a greater range and accuracy than catapults and they also can be reloaded faster than catapults. Gunpowder weapons changed war because they are stronger, more accurate, have a greater range and are able to be reloaded faster than medieval weaponry.

The lever propelling the claw tossing the object uses the law of torque and the law of energy. The gear motors moving the claw use the fulcrum of the lever holding the claw. Therefore launching the object and sending it through the air to its supposed target. The torque and energy used is supplied by the gear motor moving the lever and claw (Physics Forums).

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

One of Roman Engineering’s greatest accomplishments was the use of the arch. The arch shape is very strong, able to support great amounts of weight. This allowed Romans to build massive structures that would stand for many centuries. The Romans adapted the arch design to fit many purposes. The barrel vault is merely an elongated arch; this was used for buildings tombs and sewers. The dome is an adaptation of the arch. The dome is an arch revolved on its vertical axis. The best example of the dome in ancient Rome is the Pantheon. The basic arch was used in almost every large building in Rome. Romans also used

It is shaped in a way to transfer weight to the towers and anchors with its tension (O'Connor, 1971, p. 372). Cables are made of high strength wires spirally bound to form a rope (O'Connor, 1971, p. 372). Vertical cable suspenders that are fastened to the main cables hang the actual roadway. Stiffening girders and trusses are along the side of the bridge to distribute concentrated loads and help to keep the motion of the bridge at a minimum (Troitsky, 1994, p115).
