Catapult Research Paper

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 slingshot is a weapon used by people for generations. It was originally just a strapped sling used to propel rocks. It usually was used as a lightweight hunting weapon and sometimes for defense (Yoder.) People had used it by rapidly spinning the string and letting it go, sending the rock flying at high speeds. It wasn’t until the mid-1800 's that the traditional slingshot we all know of today came into play (Yoder.) It was a y-shaped stick with two elastic bands tied between two endpoints at either of the upper ends of the Y. It is a seemingly simple machine, where all you have to do to be able to use it was point, pull, and release. This is what made them ideal for children to play with in the late 1800’s and early 1900’s. However, slingshots are not as simple as people originally thought. Slingshots have a lot of scientific and mathematical concepts that are the reason it was such a useful weapon back in the day and a great form of entertainment today.

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

Ever thought about that one wall that you wished was never there well know you can with this easy weapon called a trebuchet is it cheap and easy to put together, it is not very dangerous so don't let your parents tell you what it is and isn't take up your trebuchet that you built and take control

Since the beginning of time, ancient civilizations have used technology for multiple purposes. It is known that Ancient Civilizations, like the Mongolian Empire, have created weapons to protect their empire. Guns, swords, and bows are some examples of weapons that have been used by major empires but it is also known that civilizations had other forms of technology that were not so advanced. Catapults are one of the oldest from of warfare weapons that have been used for the capture of territories. The greatest have taken part in the magnificents of a catapult. Throughout history, catapults have advanced through different empires and can be explained through multiple theories that were created by some of the most fascinating Scientist/ Physicist in the world.

Gunpowder weapons were so much more powerful than bows and crossbows. There are three different classes of gunpowder weapons: breaching weapons like petards, long range like cannons, and hand held weapons like the Arquebus and Matchlock. Petards were used for breaching walls and doors by placing an iron bowl filled with

Air Assault School qualifies Soldiers to conduct air mobile and air assault helicopter operations, to include aircraft orientation, slingload operations, and proper rappelling techniques. The school itself is 12 days of rigorous, fast paced training. The high standards of the school requires students to take part in a 12-mile march with rucksack in under three hours on the morning of graduation to graduate. Graduated Air Assault School second in class of 160

With the threat of zombies quickly approaching, a spring catapult needed to be built to protect Rome High School and the rest of the world from the upcoming apocalypse. That catapult is the Medieval Catapult Lier (aka MCL) which can be analyzed from the picture at the bottom of this essay. The MCL went through many adjustments such as in arm length, nail strength and tension before it could launch a tennis ball at a significant distance. Nevertheless, it was all worth it and could not have been done without the crucial subject of physics and the study of motion and energy.

There were many different types of weapons, and one major type was the bow and arrow. A bow was made for projecting an arrow a far distance. They were a huge help in ancient wars because they provided ranged combat. Traditional longbows are made from a single natural piece of wood (“Medieval Weapons” 19). The bow uses a strong flexible string to project the arrow. The force created by the bow is powered by the bows elasticity (“Medieval Weapons” 18). The design of the bow has changed throughout time from being just a simple piece of wood to highly flexible metal. Bows have been used for thousands of years, for hunting and warfare (“Medieval Weapons” 19). Crossbows were very similar to the bow; in fact a crossbow was literally a bow on a stock (“Medieval Weapons” 21). The strings on a crossbow were stronger than that of a bow and they would rarely split. Crossbows were powered by a trigger mechanism which required less manpower. There were many different types of crossbows, and they became stronger over time. With

Hurling an object towards one’s enemy may seem as old as time itself. People have hurled fists at each other, thrown spears, and launched giant rocks into enemy territory. The use of catapults, and other objects that hurl projectiles, also seem as old as human civilization itself. The effectiveness of the catapult in flinging objects over a great distance and causing destruction is due to a few basic physics principals that govern force, energy, motion, speed and mass to name a few. The design of the catapult denotes a change in modern warfare to the engineer behind weapons being just as important as the actual soldiers and people who use them.

When we think of catapults we usually imagine them firing at castle walls during the medieval times, or standing in the background of a large army clashing with another in an action movie. However, catapults have a long and intricate history that twists and binds with our own, dating all the way back to 399 B.C. First documented by the Greek historian, Diodorus Siculus, in the form of an early design for the Ballista (type of catapult). Catapults were a staple for siege warfare all throughout history. The catapult was used by many different cultures, notably the Greeks, Roman, and Chinese in siege warfare; also

The thick stone walls of the Stone Keep castles were difficult for men to knock down. Although pickaxes could be used against castles with thinner walls, it would take a very long time to knock a hole through a castle with very thick walls. The battering ram was particularly useful since the weight of several men would be put behind it. This would make it a considerable force that could seriously weaken and possibly destroy doors or walls.

Rifles, pistols, and grenades were also very useful in the world wars. Grenades were used to blow up an enemy trench without the soldiers having to blow their cover. Artillery such as canons, were very deadly to the enemy. The artillery guns were mounted on carriages. Rocket launchers were carried by soldiers and used against tanks.

The purpose of the experiment was used to determine which team created a design that ultimately proved to launch the marshmallow the farthest. What was determined to be true was that the structure that contained the right configuration in producing a high amount of force proved to have the greater amount of displacement of the marshmallow. This proved the group’s hypothesis. However, when the group was compared to other groups conducting the same experiment, the displacement of their marshmallow was the shortest. This was a result of miscommunication between group members that proceed to affect why the group had the lowest measurement of displacement. As mentioned in the research, projectile motion was shown when the marshmallow was launching
