Isaiah Nields Mrs. Ellis Physical Science 8th December 16‚ 2012 “Types of Catapults” * Trebuchet- “The word "Trebuchet" is originally French‚ and meant something like "to fall over or rotate about the middle" as in a see-saw rotating on its axle. It also seems to have meant a big‚ heavy beam. Today a Trebuchet is any kind of catapult that is powered by a massive counterweight on one end of an arm‚ and a sling on the other end. This includes Perriers‚ or "traction" trebuchets which are powered

BOEING COMPANY Their six sigma team apply the Six Sigma methodology in determining the cause of a component failure in the world’s largest commercial twin-engine airplane with millions of components. One incident was the searched for such a needle on a Boeing 777 when a recirculating air fans were rejected during functional tests on the aircraft production line‚ resulting in costly removal‚ additional testing and replacement. The team used a fundamental Six Sigma approach to examine data from the

A catapult is a device in which accumulated tension is suddenly released to launch an object in a specified direction and distance. Catapults have been used for a long time. They were used as a deadly war weapon. Catapults were first used by the Greeks‚ Romans‚ and the Chinese. They were one of the most effective weapons in war. The first attempts at catapults were to increase the range and power of the crossbow. A Greek historian named Diodorus Siculus was the first to document the use of a

The History of the Catapult We usually think of a catapult as something that was used in the Middle Ages to destroy the walls of a castle. But catapults have a very long history dating long before the time of castles and they were developed in many different ways by many different cultures over the centuries. The catapult has been used from ancient times to modern times today. The purpose has remained mostly the same over all these years. Though more recently we have had different ideas for the

Analysis: Maple Leaf Foods: Leading Six Sigma Change Maple Leaf Foods: Six Sigma in 2002 From the title‚ “Maple Leaf Foods (A): Leading Six Sigma Change”‚ one could assume that the case study is about introduction and implementing of Six Sigma in Maple Leaf Foods (MLF) company which is based Toronto‚ Canada. By observing through headings from the case study‚ one can predict that Bruce Miyashita‚ vice-president (VP) Six Sigma of MLF‚ brings Six Sigma to MLF and he implemented it. Based on

Catapults: A History A catapult has been used all throughout history as a siege engine. A siege engine is a device that is designed to break or circumvent city walls and other fortifications in siege warfare. A catapult was one of the approximately 10 weapons used in siege warfare during an assault on a castle or fortification. Some other weapons used in both ancient and medieval siege warfare included the well known trebuchet‚ the classic battering ram‚ and the siege tower. All of these devices

The angle that a catapult is built with directly impacts the trajectory of the item thrown. To prove this point one should look at the history of catapults. Another area to consider would be the mechanics of catapults. In addition‚ consider the improvements made on catapults throughout the modern times. Finally you should consider the different angles that an item is thrown from. Using information from the past and present times can help to find the best angle to accurately throw an object at

The creation of the catapult was around the 3rd to 4th Century BC (A Brief). There were three main types of Catapults: The Ballista‚ Mangonel‚ and Trebuchet. They were constructed massively up to sixty feet and larger‚ in addition‚ they were made out of wood‚ rope‚ and other materials (History of Catapults). Catapults were used as a weapon to launch stones‚ missiles‚ and other objects during warfare (History of Catapults). They were used for centuries up until the invention of gunpowder and other

Discussion The results did not give enough accurate data‚ due to the ability of the catapult and the weights used‚ the point at which the projectile stopped being efficient was not evident. If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more

Catapult Report By: Lauren Pernie & Kent Haskett 10/31/2014 3rd Period Physics Blueprint/Design of our catapult. How a Catapult Works: “Catapult physics is basically the use of stored energy to hurl a projectile the payload‚ without the use of an explosive.”1 The entire catapulting process depends on the storing of potential energy as tension of ropes or wooden arm or gravitational potential energy2 “Catapult" is the name given to a variety of related siege weapons used to hurl
