Catapult: With the arrival of fortifications such as forts, strongholds and gigantic walls to protect cities from hostile forces, conquering cities became so difficult and costly to do that every civilization must come up with an ingenious way to overcome this problem. Out of all methods ranging from complex engineering feats such as the siege tower to simple methods such as employing ladders, none are as well-known or as old as the catapult. The catapult is a siege engine that propels a variety
A catapult by definition is “a ballistic device used to launch a projectile a great distance without the aid of explosive devices—particularly various types of ancient and medieval siege engines” (Wikipedia). Catapults have been used by the Greeks, Romans, and Chinese as siege weapons throughout history. Catapults were used to “launch missiles (many different objects were utilized). These missiles were either launched directly at the wall to cause maximum damage to the fortifications or were launched
Marketing Campaigns in 2016: Will you launch, or catapult your business? There are obvious distinctions between the rocket ship, and the catapult. At first glance, the catapult is an ancient invention. Ousted by more powerful technologies, the catapult seems outdated. A rocket travels farther, faster, and is the “delivery vehicle” of the future, right? The Catapult Ancient Effective Great Range Inexpensive Simple Time-Tested "A catapult is a ballistic device used to launch a projectile a great
part of a catapult, which provides its function. Catapults are huge projectile-launching devices which have been used since medieval times. Catapults use tension when they used to use ropes to hold the basket with whatever object is loaded into it. When the rope was cut, the basket would fling upward and the object in the basket would be launched very far. The catapult was often used in warfare where they would load giant rocks into the basket and fling these rocks at the enemy. Catapults have been
The Physics of the Mangonel Catapult Catapults have been used for centuries by many groups of people, including the ancient Greeks, Romans, and Chinese. Catapults have had an assortment of purposes, but the most commonly purpose was to launch a projectile to destroy castles and soldiers. There were three main types of catapults; Ballista, Mangonel, and the Trebuchet. The mangonel was the most popular one. Different levels of torsion in the rope of the mangonel catapult decided how far a projectile
History of Catapults Catapults are a very well known type of weapon. Yet not as many people know the true history of these fine instruments of siege warfare. Many people believe that catapults where a new and very often used technology in Medieval Ages, but the first catapults are said to have come during the time between 400 B.C.E. and 300 B.C.E. by the Chinese. Gee, they’ve pretty much invented everything. Anyways, the Middle Ages didn’t “start” until 476, so saying the catapult was first built
Catapults were once used to launch furious bees and poisonous snakes onto their enemies. Catapults have influenced history and even the modern ideas of this world. Catapults were an extremely important advancement in technology, had many different purposes, and were very simple. Catapults were also very important in war. Catapults where a very important advancement in technology. One of the reasons that catapults were such a large jump in technology is because of the principle of stored energy
teacher has told us to do a research paper about the physics of projectiles involved in catapults. In an article about the physics of projectiles, I read that some models of catapults involve crossbars. Crossbars are bars that run horizontally between two vertical posts. I also read that if you control the length the arm can move it impacts when the projectile is unleashed and therefore the launch angle. A catapult depends on torque? And I found out that torque means the moment of force is the tendency
Catapult Research A catapult can be best described as a structure that uses various concepts of physics in order to launch an object across a given area in a projectile motion. Catapults eliminate the use of any explosives that accelerate the object into motion, like bullets from a gun, or cannons. The concept of catapults have been in existence since medieval times, and were extremely important during wartime. The catapult, first came into existence in Greece, which the Romans quickly learnt of
The ballista, or "shield piercer," was first developed by the Greeks using the same principles as a bow and arrow. Its primary use was to, as the name suggests, pierce enemy shields, since normal bows lacked the power to do so. Early versions of the ballista include the gastrophetes, which is nothing more than an enlarged bow that can be braced against the users body. http://members.lycos.nl/onager/GastrophetesPic.jpg As time went on ballistas were improved to become larger and more powerful
Catapults are objects that have been used in many cases of war or even work. Catapults are used all over the world. People might recognize them more when they see a movie like 300. catapults are large objects that people like I said before would use for war or for there type of work. Most jobs today do use catapults but they look different. The modern day ones look more advanced. What is a catapult? A catapult is a machine that launches an item several yards. We used catapults in war because of
Catapults A catapult is a tool or weapon used first by the people of Jeruselum to launch an object a large distance. The catapult has been used since ancient times and is still known today as one of the most effective weapons in war. The word catapult comes from 2 greek words “kata” meaning downward and “pultos” meaning a small circular battle shield. Together the word katapultos was taken to mean “shield piercer”. The earliest catapults were used under the rule of King Uzziah of Jerusalem. “In Jerusalem
Although many think of trebuchets and catapults as two different things, trebuchets are actually a type of catapult. While a standard catapult is any device that will throw an object by means of tension, a trebuchet throws and object by means of gravity from a counterweight that will fling an object by means of stored up energy, which is known as potential energy. Modern trebuchets usually use metal weights or sandbags as the counterweight, but, medieval armies would use anything from bags of stone
aircraft, the catapult system. This paper will explain the mechanics of the aircraft catapult system as well as its evolution from the weight and derrick system to the presently used steam system and new electromagnetic system that Gerald Ford-class aircraft carriers will use. How Catapults Work An aircraft catapult is a device used to launch aircraft from aircraft carriers as a form of assisted take off by assisting aircrafts to higher speeds necessary for short distance takeoffs. The catapult system consists
Catapults are devices used to launch items far distances. One type of catapult that uses a sling and weight to fly items is called a trebuchet. Trebuchets were heavily used in the Medieval Ages as weapons to fling stones toward enemies. A diagram of a trebuchet is shown in Figure I. Parts Trebuchets have six main parts: the frame, swinging arm, sling, and counterweight. For a small wooden trebuchet, it will be made with (2.5 x 15 cm) planks, a metal bar, cloth, string, weights, and bolts/screws
THE CAT-APULT(COPY) The Cat-apult was created for those who have cats that could never get moving. It can shoot up to 3 meters in distance. You place the food in the storer, turn the crank, push the arm down with your hand and voila, the Cat-apult is loaded. To fire, remove your hand from the arm. The Cat-apult can also be used with younger siblings by putting a toy or food item (below 3kgs) on the arm and firing like that. Works 85% of the time. Materials: -lots of masking tape -motor -2 5cm
The Ratapult Objective: My objective in this project was to produce a rat-trap powered catapult. It has a base of 30 cm by 30 cm, and has a theme of cows trying to escape the farm. The reason they want to escape is because they are being killed and turned into steaks, against there will. That is why I developed this ratapult, to save the cows. The cows also wanted me to ask you to eat more chicken. Hypothesis and Drawing: I hypothesize that if I build the ratapult to a 25-degree angle, and
Siege engines ingeniously used both potential energy, kinetic energy and rotational kinetic energy to throw things very far, fast, and even accurately. Besiegers could fire 100-200 pound stones up to 1,000 feet. The main siege weapons were catapults. The catapult was used to destroy buildings and walls inside and outside of the castle, and it could also destroy an enemies morale by throwing severed heads of comrades. The earliest model was the trebuchet. It started by using a large weight on one
History of catapult The history of catapult spans far from ancient time, until modern times with the basic principles remained the same. the designs became more complicated, but the intent is the same (shooting an object, such as rocks, into the air). The catapult history started when men thought of the idea of shooting a missile at a target. And then it became more advanced. For example the theory of the sling shot operated the same. For using in siege warfare, people believe that catapult history
Catapult Investigations Planning: Aim - This project involves testing a catapult by using a rubber band to catapult a mass using various forces. Our aim is to choose and investigate variables of our choice and its effects using a simple catapult. Preliminary method - 1.
