Simple Catapult

There are many approaches to this problem. The most common method is creating a separate air chamber using an empty soda bottle. A weight drops on this bottle to exert air pressure. This air pressure is then used to launch a projectile, adjusting the height of the weight as needed. Although easy, this method is too imprecise and will yield inaccurate results. To begin, it is needed to learn about how air pressure is created and the best way to achieve it. After

In response to the use of castles and fortresses, siege weapons were created. Siege weapons ranged from short range weapons such as the battering ram to longer range ones like the trebuchet or the ballista. The battering ram was usually a big shed with an armored roof and wheels to protect the men inside operating a thick beam with an iron head hung from the roof that was swung into enemy walls to bring them down. The siege tower, a wheeled tower filled with men that would be used to get over the walls, also saw its use during this time. The trebuchet was used for longer range, the missiles launched by the trebuchet ranged from using dead bodies of animals or people to spread disease, a primitive example of biological warfare, to using large boulders to take down fortress walls. In response

The way a Trebuchet works is that a counter weight drops which pulls the arm forward and at the point of takeoff a pin releases the object that is being projected. The counterweight drops using gravity and is attached to the arm causing it to fly up and launch the object. Engineers have had previous experience in this field because of the world wide trebuchet launching competitions. One example of engineers making this trebuchet are the engineers from team NASAW in the Pumpkin Chunkin ' competition. Team NASAW has a trebuchet with a heavy weight and a long arm. There arm and weight start next to each other at the beginning. The weight drops forward and like a whip the arm swings around and fires the pumpkin into the air at insane speeds. They are one of the top competitors in the competition and have proven countless times that the design works wonderfully.

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

The catapult is a machine that launches an object into the air by using sudden tension. When people launched catapults, the object that was launched forms a parabola to hit the target otherwise known as a projectile. There are forces that act upon the object such as gravity and initial velocity. To calculate where the object lands, people use the vertex form and the quadratic formula. The vertex form is y = a(x – h)2 + k in which a is equal to the slope of the parabola, h is equal to half of the x value and k is equal to the y value of the maximum point. Also, people can find the farthest distance where an object could land by using the quadratic formula. Therefore, vertex form and quadratic formula are used to determine the path of the catapult’s

This second edition of DeVries and Smiths’ book, Medieval Military Technology, encompasses many of the weapons, fortifications, vessels, machines, and armour developed throughout the medieval period, to provide a brief cultural history of the relationship between military technology and medieval society. DeVries and Smiths’ purpose in compiling this book was to lay out their argument in a way to which the reader can understand the purpose of medieval military and its relationship to society. The central

Have you ever wondered how they would break down castle walls in the middle ages or about middle age warfare in all. I am going to build a trebuchet to learn more about Newtons Laws of Motion and how these simple yet complex machines ruled the battlefields in the middle ages. I became interested in this topic because I am fascinated by middle aged weaponry and machines. This will be beneficial to my knowledge to help me understand Newtons Laws of Motion and about these giant machines. I believe that learning more about Newtons Laws of Motion may help to explain why different designs affect the trebuchets range and power.

We needed to fully utilise our knowledge by applying all the basic concepts in physics such as dynamic equilibrium and knowing the stiffness of the materials to build strong miniature bridge using given items to withstand the weight applied.

The first records of counterweight trebuchets began appearing in the 12th century. Proving to be an excellent siege weapon, many militaries began using this. Though stone-throwing artillery had been employed by both the Greeks and Romans, they were usually powered by torsion or tension; the trebuchet was the first war machine to use gravity and leverage to fire projectiles. They were used widely during the Crusades, in which the European militaries, especially the French, used the trebuchet to lay siege to Muslim cities in the hopes of capturing the “holy land.”

Ever thought about that one wall that you wished was never there well know you can with this easy weapon called a trebuchet is it cheap and easy to put together, it is not very dangerous so don't let your parents tell you what it is and isn't take up your trebuchet that you built and take control

The discovery of gunpowder changed war from being fought with medieval weaponry and battle tactics to more modern day weapons and tactics because the gunpowder powered weapons are more deadly. Weapons that use gunpowder to launch projectiles have a greater range than melee weapons and are more powerful than bow and arrows. Also, cannons are more powerful and have a greater range and accuracy than catapults and they also can be reloaded faster than catapults. Gunpowder weapons changed war because they are stronger, more accurate, have a greater range and are able to be reloaded faster than medieval weaponry.

The physics concepts associated with them are projectile motion, energy, momentum, forces , speeds, and distances. The kinds of catapults all use the same theme of accumulated tension, but acquire that tension in their own way, their own design. The Mangonel catapult for instance, is what most of us think of as the traditional catapult. A large wooden device with four wheels and a spoon that launches fireballs. The Mangonel stores energy much like a spring would, therefore, we use the equation PEspring = 1/2kx^2. The tension in the ropes and arms of the catapult when pulling on its long arm stores potential energy which is transformed into kinetic energy when fired upon.

The trebuchet catapult “hurls” stones or other projectiles into castle's walls, destroying them quickly. It mainly consists of a long arm that is balanced on the fulcrum that was far from the center. There is a rope that attached to the long arm, until the counterbalance was high into the air.

There are two main types of energy that take effect on the catapult for it to work. The first one is Potential energy. When you pull the fork back the rubber bands are storing Potential Energy. The second energy is that helps is Kinetic Energy. When you let go of the fork the Potential Energy is transformed to Kinetic Energy. This is because when you let go the object will move because energy due to motion.

The catapult was first invented in the year 400 B.C. in a Greek town called Syracus. Workers for Philip the II of Macedon , the father of Alexander the Great, most likely invented the ballista ,an early version of the catapult that resembled a giant crossbow. The ballistas could stand to about 8 feet. Catapults were probably used to knock down the big, strong walls of castles. There were also catapults that originated in China in the third or fourth century B.C. that were very similar to the ones from Macedon and Greece. Later, the Trebuchet was invented. To use the Trebuchet you put a stone in a sling and pulled down on the shorter end. The stone sitting on the longer end would go flying.
