Catapult Research:
Which societies used the catapult?
-The 3 societies that used the catapult were the romans, greeks, and the chinese.
What types of catapults?
-There were a few catapults. The term catapult was used to define a very large machine that was used to hurl objects great distances. The three variations were the mangonel, trebuchet and the ballista, the trebuchet catapult is different from the ballista because it used gravity and a seesaw effect to hurl its projectiles great distances and the ballista which used twisted skeins of material to create torsion because that was its way of storing energy for the release of the projectile.
Why did they use catapults?
- Catapults were used to launch large projectiles such as stone to destroy the walls of castles so that they could get into the castle by foot or other objects such as boats and they could get in a lot easier.
What purpose did catapults have in their society/history/social advancement?
-They were used for many things, there main purpose was to siege war against others and to break down the walls of things such as castles so that they could send in ground troops. They were also a big social advancement because not a lot of people had the, the only people who had them were the Romans, Greeks, and the Chinese.
What are some applications of catapults in Modern Day technology
-An application of catapults in our Modern Day would be such things like a crossbow or bowgun, they are just like catapults because when you are using a crossbow you are pulling the string back as well as the arrow and when you are holding it back you have created energy and you are now storing it and when you release your grip on the string the energy that was being stored is getting released and that is what causes the crossbow to fire and that is what a catapult did.
What are important mathematics concepts used when building/designing a catapult?
-The important mathematics concepts that a student must know when building and designing a catapult would have to be knowing how to find linear and quadratic functions, and be able to use a little bit of the Pythagorean Theorem as well as some physics because the students will be launching objects so they will need to have some knowledge about projectile motion.

Catapult Essay:
There were catapults that once threw stones! The few countries that used catapults were the Romans, Greeks, and the Chinese. The kind of catapults that they had used were the Trebuchet, Ballista, and the Mangonel. The catapults all had the same purpose and that was to be able to break down the walls of castles and siege war against their enemies. There were also a few differences in the catapults as well. The Trebuchet was different from the Ballista, it depended on a seesaw effect and gravity to carry it through the air but the Ballista and Mangonel didn’t need to depend on those things. The Ballista and Mangonel were quite similar though, they both relied on torsion to be able to throw the stones large distances while the Trebuchet didn’t rely on torsion like the Ballista and Mangonel. The Romans, Greeks, and Chinese used the catapults to launch large projectiles such as stone to destroy the walls of castles so that they could get into the castle by foot or other objects such as boats and they could get in a lot easier, catapults had quite a big purpose in their society.They had a big purpose in their society, it helped the Romans,Greeks,and Chinese fight in their wars and they had a big effect on the wars as well as it had an effect on their social advancement, it helped with the social advancement because there were only 3 countries with catapults. Catapults had such a big effect on them and they were more advanced than others.
The Trebuchet the quite unique one. It was quite a sophisticated counterweight catapult although it was very sophisticated it was still very effective. It was a very effective catapult due to its amount of range and it had a lot of power behind it and was able to take down the castle walls. Since the Trebuchet was such an effective catapult it was given the nickname “Bunker Buster”.
Well other than the Trebuchet there were two other catapults, the Ballista and Mangonel were quite similar catapults.The catapults both used torsion unlike the Trebuchet which used a seesaw effect. Just like all the other catapults they were used for the same reasons and they were still very effective during the time. At the time they were used, they were “Weapons Of Mass Destruction” and had a lot of range and did a lot of damage to those castle walls.
Nowadays there aren’t anymore catapults that are used to break down castle walls. In todays society there are catapults that launch pumpkins thousands of feet. There are also many other things like catapults that some people use everyday, the catapults that we use now are crossbows and bows. If you didn't know crossbows and bows are like catapults because they use the same mechanics that catapults did, they use torsion.
Although there are many other catapults out there I would still like to make one.The catapult I would make would be called “The 4th Of July 2.0”. If I were to make a catapult, I would make it like the Trebuchet but before it launches the projectile it puts a dozen fireworks onto the projectile and when in the air the fireworks catch fire and launch the projectile farther in which will make it go faster. That would be my catapult because that would just be awesome.

- What was the project about? Why did we do this project? What mathematics and design concepts were applied?
- This project was about catapults and how they work. The purpose of this project was so we could learn projectile motion as well as learn how to work with a group of people that we can use the Stanford School of Design.
- Describe the prototyping process. Does your final catapult resemble the prototype? Why or why not?
- I would say that the prototyping process was very easy. My groups final product does not resemble our groups work very much. It doesn’t resemble the final product that much because in our prototype we had a base and our catapult had legs that supported the cannon and our final product did not have that.
- What were some last minute adjustments you had to make to your catapults prior to the Launch Date?
- My group and I made quite a few last minute adjustments. We had added many things last minute. We added a coil that was never part of our plan and we also had to get rid of the support legs which were part of our plan but we never had time to get them onto our catapult.
- This question is pertaining to your group research: when making calculations, what were some of your limitations? What were some things you “ignored” for the sake of simplicity?
- Our whole design was quite simple, although it was simple we had to make a few cuts with the wood a few degrees shorter because the saw doesn't go to that angle. But overall we didn't ignore any of the other requirements for the project.
- What were some of the successes you experienced while working on this project?
- The successes that we had in this project were we were able to get all the measurements for everything very easily and we got everything put together pretty quickly.
- What were some challenges you experienced while working on this project?
- A few challenges that my group and I faced were we weren't exactly sure how to make the air be released into the chamber all at once so it could fire the baseball but when we finally found out how to do that our tank ended up having a leak and we couldn't fire our air cannon.
