Catapult Essays

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

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

Imagine getting put in jail for nineteen years for stealing a loaf of bread. This is what Jean Valjean had to experience. Jean Valjean, the main character of Tom Hooper’s drama Les Miserables, gets out of prison, where he was put for stealing a loaf of bread, at the beginning of the movie. After being told that he’d be let out of jail, his dreams of living a normal life were utterly shattered within a couple seconds. This happened because Javert gave him a slip of paper marking him as a ‘dangerous’

The Charlotte York Irey Theatre presented an electrifying performance Sunday as BFA students demonstrated their artistic creativity intertwined by influences from their academic careers in the dance concert Catapult. Catapult featured four experimental performances, each one as unique as the other in respect to their individual choreographers: Taylor King, Kaitlyn Lawrence, Mattie McGarey and Olivia DeMoulin. As the eager audience took to their seats, a dense cloud of theatrical smoke slowly encompassed

Aircraft Catapult Military aircraft are often required to operate from very short runways, such as aircraft carriers, where the runway length is too short to allow the aircraft to take off conventionally under its own thrust. An aircraft can only take-off once it produces a lift force greater than its weight in order to accelerate vertically. From the Lift equation: L=1/2 C_L ρAV^2 Where L is the Lift force, C_L the lift coefficient, ρ the air density,A wing surface area and V the velocity. [1] The

In this project, David and Goliath, assigned by Mr. Kumz, a catapult was built, Springy.. In this experiment three different variables were tested; angle of launch, stretch length, and the skittle position. The angle of the launch had three measurements: zero and forty-five degrees. The stretch length measurement were 2, 3, 4, 5, 6, 7, and 8 centimeters, while the skittle position was flat and on its side. Springy’s most effective launch was at a zero degree and with a stretch length of five centimeters

History of the Catapult Catapults possibly the most well-known weapon in medieval warfare, some with the ability to shoot a rock or body over 1,300 ft. into enemy lines. However catapults date back a lot further than medieval times, and came in many more styles than you might think. The catapult was the ultimate long range weapon until the 14th century when gun powder and canons were introduced. The first documented catapults originated in the 3rd and 4th century BC in China. The catapult was operated

don’t know how long it will take to breach it. Let’s aim all the catapults at the west wall and see what happens.” “Yes, my lord,” Sir Faine replied, now understanding why he had elected to stop the assault on the towers and direct it to the west wall. “Unless they expect reinforcements, it won’t matter because once we break through, Whitefield will fall. Sir Faine, round up every available soldier to help in moving the catapults. Make haste for time is our enemy now.” “Yes, my lord.” Running

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

A Rube Goldberg project is a complicated way to do a simple task. In our project we decided to crack an egg. We designed a complex way in order to do this simple task. First of all, we decided to have a catapult fling a bouncy ball into to dominos which would set off a mousetrap. Then, the mousetrap would pull a string to releases a ball down a slide. The golf ball would fly down a race track and then set off another mousetrap. Next, the mousetrap would pull a string out of a book which would close

-ANCIENT GREEK- WARRIORS THESIS Ancient Greek warriors were great fighters because they had excellent weapons, technology, and training. Guiding Question What made Greek warriors such great fighters? Ancient Greek Training ● A boy went to a training camp at the age of 7 to become a hoplite. ● Once at camp the boys were given small, child-sized helmets and shields. The reason for this was so they got used to the weight of them. ● The young boys would be trained in different

reasons for the trireme being so fast and maneuverable, but also the cause of its inherent instability in rough seas. Thus the focus shifted to boarding actions and attacks with flaming projectiles from the several catapults that could be carried by these larger ships, as opposed to the one catapult carried by some triremes. Triremes could also be unarmoured (aphractos), like the Athenian Triremes, as opposed to armoured (phractos). The Athenians built their ships in this way to facilitate the fast, rapid

Roman ships by burning the sail, and eventually the entire ship, nearly killing everyone aboard (Source A). Using the crane, he was able to up-end any ships that were not already on fire or sunk (Source A). As an alternative, he used the improved catapult to sink enemy ships from far distances (Source A). Archimedes influenced our lives today, some different than others. In the realm of mathematics, without Archimedes, we would not know the area of a circle (Source A). In science, we would not know

The Life of Crusader The Book of the Lion by Michael Cadnum is a novel based in Medieval Europe and is about an apprentice named Edmund who joins Richard the Lion-Hearted to fight in the Holy Land during the Third Crusade. The novel is narrated in first person or in Edmund’s point of view as he experiences many battles that are actually historically correct such as the main battle, Battle of Arsuf. Michael Cadnum correctly portrays hand-to-hand warfare and also horse and lance battles. Military

activities as one campsite,there were a lot of campsites.All the campsites were competing for the ribbons,the ribbons were earned by earning the most points.For each ribbon,there were ribbons for 1st,2nd,3rd place.There were a lot of activities like mini-catapult,spider crawl,first aid,bean bag jump,plank walk,archery,and

meaning wild ass since its kick was so tremendous. The onager is a variant of a mangonel which falls under the category of catapult. It is very similar to a catapult in the sense of its appearance and operation. However, there are some slight differences between a typical catapult and an onager. The onager used a hook with a pouch that would carry a boulder compared to the catapult which used the spoon mechanism. The reason the Romans preferred the hook and pouch was because it was more accurate than

there. It is at this point that the Loonies are starting to waiver on their belief in the revolution and they are turning on their own leaders. Earth then retaliates with a second attack, which destroys Lunas first catapult, but they already have built a smaller version of the same catapult and continue to attack Earth until they cave in to Lunas idea of independence. And this point Luna is crumbling and so are their fighters. The professor goes in front of the crowds of people and proclaims victory

starting mechanism for roller coasters is the Catapult Launch lift. To further explain, “In some newer coaster designs, a catapult launch sets the train in motion… Instead of dragging the train up a hill to build up potential energy, these systems start the train off by building up a good amount of kinetic energy in a short amount of time” (Harris, 2). Simply put, the difference between the Chain lift and the Catapult Launch lift is that the Catapult launch lift is set into a fast motion very quickly
