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

Zac Jordan‚ Ryan Breaux Catapult Project Sharkey Catapults have been used since Greek and Roman times. They were used as siege engines against castles and walled cities. The ammunition loaded into the catapults were meant to break the walls with stones‚ fire incendiary missiles over the walls‚ or used for biological warfare‚ such as launching dead animals over the wall to spread disease. The type of catapult we built is a mangonel catapult. We like to call it RZYAACN (our names combined and

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

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

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

ABMAMACAW Catapult Catapults were first made to hurdle cats (on a more serious note). There are many different types of catapults‚ such as the mangonel catapult. The mangonel catapult which our catapult is based on was created in 400 B.C. by the Romans. The mangonel was created like the Greek ballista but was smaller and mobile. Our catapult was based on some aspects of the mangonel. In the following I will talk about the process and materials used to make it and the science of the catapult. Some

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

Catapults have been invented by the Greeks‚ Chinese‚ and Romans. The first catapults were early attempts to increase the power and range of a crossbow. Catapults were used to launch objects; these objects were either launched at the walls to cause great damage to the fortifications or were launched over the wall to effect on the population within the walls. Catapults were also used to throw objects at enemies. The Ballista is basically a giant crossbow. To have been created by the

A catapult is an ancient device used to launch heavy objects at targets during war. The catapult dates all the way back to 400 be when it was invented in the Greek town of Syracus. The main types of catapults are trebuchet‚ mangonel‚ onager and ballista. There are many more types of catapults also. Catapults were an absolute revelation in weaponry. The mangonel was best suited for launching projectiles at lower angles to the horizontal‚ which was useful for destroying walls‚ as opposed to the
