  • DIY Science Catapult
    DIY Science Catapult How can making a catapult help you prove something that it took mankind millennia to work out? Look at the science behind siege engines in the DIY Catapult! Historical Overview On War Machines and Mangonels One of the problems with warfare throughout history was that enemies had the annoying habit of hiding behind fortifications. The solution: to find a way of beating down, piercing or otherwise destroying part of the wall so as to gain entry. Alternatively, it was equally important to be able to keep others intent on destroying your walls at bay. Enter the one- armed throwing engine. What’s a Mangonel? The Greeks c200 BC referred to these one-armed machines as among numerous devices that could be used by the defence against a besieger’s machinery. People from the Mediterranean to the China Sea developed war machines that operated using the elasticity of various materials. The term catapult is used to describe all of the different types of throwing machines. What you and I know as a catapult is actually a mangonel, otherwise known as an onager. Onager was the slang term derived from the Greek name for ‘wild donkey’. This referred to the way the machine ‘kicks’ when it’s fired. The correct term for the machine is mangonel - derived from the ancient Greek term “manganon” meaning “engine of war”. Historical Evidence There is very little archaeological or historical evidence on the mangonel. However, the Roman, Ammianus, does describe one in his writings, but the proportions of the machine are unknown. There remain some medieval illustrations of the machines and some speculative drawings from the 18th and 19th centuries.

Hiding behind something is helpfu[, but what if your enemy is able to break down your barrier? Throughout history, finding a way to destroy the enemy's protection while maintaining a safe distance was cha[[enging-untilthe invention of the catapult, the one-armed throwing machine. Ancient Greeks referred to the catapult as a mangone[, meaning "engine of war." The mangonel, weighing approximately z tons, functioned by ftinging heavy objects over and through walls. Because of its powerful kicking motion, mangonels were also referred to as onagers, a name derived from onagros, meaning "wild donkey." A ballista was another type of catapult. lt was designed similarty to the crossbow. Ballistas relied on the work of torsion to release ammunition that looked like giant arrows. Over time, gravity catapults, such as the trebuchet, were invented. Trebuchets were designed to hur[ a heavy object into a high arc, which was quite useful for breaking down castle walls, especially if the ammunition involved fire. Catapults have been one of the most effective weapons for warfare. A sling is attached to the end of the catapult's arm. ln lowering the arm, the user stores energy in the ropes, and when the arm is released, the arm is flung forward.

    1 Christine Moll-Murata The Rise, Organization, and Institutional Framework of Factor Markets, 23-25 June 2005 http://www.iisg.nl/hpw/factormarkets.php GEHN Workshop Utrecht, June 2005 The Rise, Organization, and Institutional Framework of Factor Markets Christine Moll-Murata Working for the State: The Chinese Labour Market for Manufacture and Construction, 1000-1900 Please do not cite without permission from the author [email protected] This is a report on work in progress from a project that focuses on state administration and self organization of the crafts in the Qing Dynasty (1644-1911).1 In Chinese craft historiography, the transition from labour obligations for artisan households to a system of hired labour in the official sector between the fifteenth and seventeenth centuries is generally considered as the most important institutional and legal change. While there can be no doubt about the impact of this reform, we have sought to find out about earlier institutional arrangements as well, and to explore the intra-dynastic transformation processes. Present-day Chinese historiography most often treats craft production in the service of the state, the “official crafts” as quite distinct from that in the private sector (“civil crafts”). Such an approach implies that the effect of dynastic economic policies was to create “a closed and self-sufficient part of the feudal economy, which was ultimately incompatible with private handicraft industry”. 2 We will explore how far this characterization is accurate for the periods covering the dynasties Song (960–1276), Yuan (1279–1368), Ming (1368–1644), and Qing (1644–1911). It is useful to take this long perspective for a later global comparison of the role of the state in pre-industrial economies.

  • Military Technology in the 12Th Century
    Zurich Model United Nations MILITARY TECHNOLOGY IN THE 12TH CENTURY The following list is a compilation of various sources and is meant as a refer- ence guide. It does not need to be read entirely before the conference. The breakdown of centralized states after the fall of the Roman empire led a number of groups in Europe turning to large-scale pillaging as their primary source of income. Most notably the Vikings and Mongols. As these groups were usually small and needed to move fast, building fortifications was the most efficient way to provide refuge and protection. Leading to virtually all large cities having city walls. The fortifications evolved over the course of the middle ages and with it, the battle techniques and technology used to defend or siege heavy forts and castles. Designers of castles focused a lot on defending entrances and protecting gates with drawbridges, portcullises and barbicans as these were the usual week spots. A detailed ref- erence guide of various technologies and strategies is compiled on the following pages. Dur- ing the third crusade and before the invention of gunpowder the advantages and the balance of power and logistics usually favoured the defender. Another major advancement and change since the Roman empire was the invention of the stirrup around 600 A.D. (although wide use is only mentioned around 900 A.D.). The stirrup enabled armoured knights to ride war horses, creating a nearly unstoppable heavy cavalry for peasant draftees and lightly armoured foot soldiers. With the increased usage of heavy cav- alry, pike infantry became essential to the medieval army.

  • The Mighty Roman Mangonel
    The Mighty Roman Mangonel Dear Student, This exercise gives you a fun opportunity to explore some of the important aspects of engineering:- design, structures, materials, dynamics, scientific programming and sensors, to name but a few. The value you derive from it will depend on the quality of teamwork involved and on how deeply you think about these topics. As you read this document, you will note that the size of most of the component parts of the machine have been predetermined. Initially, you are free to make choices on the length of the ‘throwing arm’, the number of loops in the “skein” and to what angle the throwing arm is winched (the meaning of the terms in quotes will become clear as you read on). After you have assembled the Mangonel and tested it as is, you will have the opportunity to replace the throwing arm and “Missile” holder with one of your own design. Decisions on these values should be made at team level and be based on scientific considerations. G.L. & G.B. 2007 What you should find in your kit: Quantity Per Part Name Spec.

Catapult has been used since ancient times and has been proven the most effective mechanism during warfare. This weapon is used to hurl projectiles to a distance. This is a simple device that can store energy to release a projectile when required. Catapult can be classified as tension catapult, torsion catapult or gravity type catapult. Through the process of sketching, constructing and testing, a simple catapult was constructed. The catapult was modeled on design software and proper testing for distance and average velocity was done. Keywords: Catapult, tension type catapult, torsion type catapult & gravity type catapult. 1.

    THE INFLUENCE OF HISTORY ON MODERN CHINESE STRATEGIC THINKING By S. Elizabeth Speed, Ph.D. 106 - 1386 West 73rd Avenue, Vancouver, B.C., V6P 3E8.

Unfortunately, the author, Elizabeth Speed, was unable to complete the project due to health concerns. Rather than toss aside the useful analysis that was already prepared when she had to withdraw, the decision was taken to publish the portion of the project that was completed. The focus of this project was always very ambitious. With a recorded history of nearly three millennia, any attempt to derive “lessons” from such a record would be extremely difficult. As Dr. Speed indicates in this paper, it would also likely fail. Nevertheless, it is probable that the enormity of China’s national history is why so many people have resorted to cherry-picking that record. At no time is this more evident than in our own age when, as China regains a leading position in global affairs, observers are actively endeavouring to understand what this might mean for the future. What can that country’s past tell us – many of whom are not Sinologists – about its likely actions in the future? It is a truism to assert that history influences the current generation of Chinese leaders.

  • Science Cycle 2 Week 22 Popsicle Stick Catapults by Robyn Cooper
    Cycle 2 Week 22 Hands-On Science script for all ages - Popsicle Stick Catapults, by Robyn Cooper Today we are going to think like engineers. Engineers use science, math, and even art to solve problems. Our problem is to launch an object using a catapult. Before we start science today, let’s sing the scientific method. [Sing the song, to the tune of Pop Goes the Weasel. “The Scientific Method is Question, Research, Hypothesis, Experiment, Analysis (clap!) and conclusion.” We are going to talk about building catapults today. What’s our Question? How can I think like an engineer to build the type of catapult that launches an object the farthest possible distance? • Now, what makes a catapult, a catapult? Let the kids brainstorm. A catapult is a ballistic device used to launch a projectile a great distance (without the aid of gunpowder or other propellants) – particularly various types of ancient and medieval siege engines. Have you heard of a slingshot? That’s a catapult! Remember David and Goliath? He used a sling and a rock to knock that giant down! • What problems do catapults solve? Let the kids brainstorm: They allow someone to launch objects far distances. The catapult is a simple machine. Primitive catapults were the product of relatively straightforward attempts to increase the range and penetrating power of missiles by strengthening the bow which propelled them. • What do engineers need to consider when they are designing a catapult? Tell kids, “Don’t answer this yet, we’ll come back to it.” Let’s do our research. There are three main questions to ask in our research: • What are the parts of any catapult? • What kinds of catapults are there? • What is the science of catapults? But to answer this last question, let’s first think about what kind of work does a catapult have to do? Let’s talk about parts of a catapult first (see below).

They’d also have used twisted rope to power the spring, rather than an elastic band. Mangonels weren’t very accurate, but for flinging rocks at castle walls they were good enough.
