Ballista Essays

The ballista was a Greek siege weapon adopted and improved by the Roman army after their conquest of Greece in approximately 146 BCE. In the centuries to come the ballista would become a standard part of each Roman legion- despite being a prohibitively expensive and labor intensive machine to build and operate. All the while the machine grew larger and larger, one reportedly being used to fire bolts 1.1 kilometers across the Danube River. The ballista, at least in the form seen during the late republic

This science fair project is a mechanical catapult that will be electrically modified to pull back on its own. The goal of this project is to see how far an eraser cap will launch with two different forces that pull the catapult arm forward very fast. From this, we will see if either a bungee cord, or fifty to one-hundred rubber bands has more elasticity. One real-world situation we would want more elasticity for is holding things together, or hooking things together. In this project, recording of

Catapult Project  Sketch - Question - How does building a catapult allow us to better comprehend 2 dimensional motion in physics?  Hypothesis - I believe my catapult will fulfill its purpose, but not launch as far I’d hope, since it is my first time making one.  Background information - During the Middle Ages catapults served as important weapons; but not just any catapult one, with the trebuchet design. These were used to hurl heavy stones to smash castles and city walls, even reducing them to

Arguably the most dominant empire throughout history was the Roman Empire due to their capability of conquering land. Being triumphant during battle required an effective strategy. Romans mastered taking land during siege warfare. However, there were many moving pieces that were involved during a siege. In order for one to gain a full understanding of Roman siege warfare, one must gain knowledge about the tactics utilized, artillery used, and the siege engines crafted during the attack. (83)

appeared in England in the middle ages in the year 1216. Ancient catapults were used frequently in China, Greece and ancient Rome. Whereas medieval catapults which were adapted from the ancient catapults were common in England and France. The Ballista The Ballista is a large crossbow like catapult believed to have been created by the Greeks but later adapted by the Romans. To fire it the operated would attach the rope onto a winch which would draw the rope backwards and would result in the large wooden

the Roman Legions. In the first paragraph about the weapon he references the idea of standardization by saying “No Ballista, however, is made without regard to the given amount of weight if the stone which the engine is intended to throw.” Vitruvius is referencing that all ballistae are meant to throw a certain weight of stone, instead of trying to find stones that fit the Ballista. Standardization was not something foreign to the Roman Legions, they built the famous Roman roads that followed a strict

Christopher Wolfe Mr. Saleeba English IV Date (Day Month Year) Leonardo da Vinci Was Leonardo de Vinci a great leader? I will be giving facts about his life and the many accomplishments that he made. I will go into depth on what characteristics made him a great man and a renounced leader. I will tell you what the mindset of this brilliantly insane man might have been. Leonardo was a painter, inventor and a man of culture that was born in 1452, he was more noticed for his brilliant art and his

Lasting 500 years with the republic and roughly a thousand and five hundred more with the Roman empire, the Roman Army was an extremely effective fighting force. Creating new tactics, some still used to this day, the ancient Romans were able to conquer most of Europe, northern sections of Africa and parts of the Middle East. With a complex chain of command, adaptability, formations and equipment, the Roman armies were the best for their time. In the beginning of the first Roman army, the Romans followed

The Roman army conquered territories due to their innovative organization, training programs, and advanced weaponry. The Romans developed a highly effective system for organization that was far ahead of their time, allowing them to form one of the greatest empires ever to exist. To begin with, the Romans had a clear command structure of cons stationed in Rome and controlled two legions of around 22,000 soldiers. The tribunals led the legions, and each legion had six of them. A pair would lead for

Rome was regarded as one of the most powerful nations, and we have learnt throughout the past several weeks how it conquered and dominated other nations. During the Battle of Corinth in 146 BC, Rome subjugated Greece. Despite this accomplishment, Greek is acknowledged to have had an impact on Rome's civilization through literature, education, architecture, philosophy, and the arts. Influence on Roman religion and mythology Early Roman and Greek religions established a polytheistic system of worship

Medieval Europeans had a variety of weapons and siege craft used for battling. The weapons categories are bladed hand-held, dulled hand-held and long range hand-held. Categories of siege craft include catapults, scaling ladders, siege towers, and battering rams. Another siege strategy is tunneling. Weapons The bladed hand-held category includes swords and daggers. The swords consist of arming swords, broad swords, falchions and long swords. The most famous of these is the arming sword, often called

Roman Technology The Ancient Romans were very skilled engineers. They had many ideas that turned into reality. Without the Romans’ advanced engineering skills and ideas, the world would not have the same technological advances. The Romans made many technological advancements and inventions. The Romans use of new building materials allowed them to make stronger, bigger buildings. Many different materials and designs such as concrete were used by the Romans for building (Macdonald). Concrete

During the years of 550CE – 1550CE, also known as the ‘Middle Ages’ or ‘the Medieval Period’, the times were gruesome and filled with bloodthirsty knights, unlucky peasants and slaves and most of all, rich Kings, Queens, Lords and Barons. During these times, kingdoms wanted more land to rule over. This lead to lots of wars and deaths. To protect themselves during these hostile times, the French and the English built castles. Castles originated from France after the ‘Battle of Hastings’. The ‘Battle

Have you ever wondered what the inventions of medieval times were like? How people did things such as grinding grain? Well, now you will know what it was like. Medieval innovations are fascinating for three reasons. We know about how they did everyday things, what science was like, and how they affect our scientific progress. Windmills are one type of invention. Windmills were brought to Europe in the 12th century by the crusaders. The sails (the things that turned in the wind) were mounted on a

city in a pile of rubble. Before the Mongols were able to get into the city, the people of Nishapur put up a fight (Document 4). They lined the wall with three thousand crossbows and had other lines of defense including hundreds of mangonels and ballistas (Document 4). They tried their best to hold off the army of Mongols, but they weren’t able to. The Mongols got to the wall and wasted no time to get into the city. Once they were in, they drove all of the people out on the the plains to be executed

Castles were know for a long time about their king's,knights,queens,and princess. But in this report i will tell you about what castles is made of.What there advantages were and there disadvantages.Also what the interior looked like. Also all the names of the concentric castles. Did you know that castles were made of sandstone,hard chalk,limestone,and flint. Lime mortar kept the stones in place. White plaster was used to cover the walls of the castle and the interior walls. Metals such as lead

and bows and arrows. The soldiers were trained to use the weapons, and they would practice when they were not fighting. The Roman soldiers used catapults that could throw huge rocks and knock down walls. They also had crossbows that were called ballistas that shot arrows that were the size of spears. They often practiced with swords made of wood. The centurions wore large crests on their helmets so the soldiers could see them. The soldiers usually marched 20 miles in a day and carried 90 pounds

crossbow, and it was called Gastraphete. It also functioned similar to a crossbow. Likewise, the first catapult was also small in size. Since, the Greeks found this new invention useful, the inventors created an enlarged model of Gastraphete, naming it Ballista. The catapult was created in the Middle Ages, and it was primarily used for castle sieges, and to protect the castle against enemies. This is why the Greeks decided to create a larger model. Seeing the immense destruction it caused the opposing side

Although Leonardo Da Vinci was a talented painter that made the Mona Lisa and the Last Supper, 2 of the most famous paintings in the world, he was more than just an artist. In Da Vinci’s notes we have found that art wasn’t the only thing he was interested in. Da Vinci’s notes are filled with incredible designs and drawings of discoveries and machines that were basically glimpses of the future. Leonardo Da Vinci was a genius whose ideas and inventions were decades ahead of his time. Da Vinci had

4000 years ago we saw the very first civilizations develop a system of writing, complex mathematics and invent the wheel. Today we have already sent exploration rovers to mars, and are looking to send people there within the next 10 years. With the first homo sapiens appearing 200000 years ago, it is quite amazing that most advancement in technology and science has happened in the past few thousand years. However the progression in science has not always increased at a steady rate. For example during
