The trebuchet was capable of taking down castle walls, fortresses, and entire cities. They were used as an ancient war engine in the early 300 B.C. in Ancient China. The trebuchet reached Europe in the Middle Ages, in the year 500 A.D. It was originally primarily used by the French, and were temporarily used as a power source. It will later be used as a weapon, introduced to England during the Siege of Dover in the year 1216. The trebuchet was used to take down the Dover castle's walls in this Siege. Trebuchets are torque based launchers, using an arm with an attached form of sling and a counterweight to throw a given object further than the traditional catapult. The counterweight must be much heavier than the payload, or the object being launched, in order for the launch speed to be quick enough for the projectile to reach its target. One end of the sling will release when the projectile is over the counterweight, and as a result, the payload is released and has begun its flight to its target. A trebuchet consists of a pivot point, an arm, a sling, counterweight, and a stand. The arm is attached to the pivot …show more content…

The sling will be 18 inches, or the length of the longer end of the arm. I will use a metal pivot point, in order to keep stable and support the weight of the counterweight. The counterweight will be 4985 grams(13 pounds), or approximately 133 times heavier than the payload, which is 45 grams, as according to Siano’s optimal factors of the Trebuchet. The sling will be a string, fully attached on one side, but only a loop around a rod to be released at the optimal release location of 45 degrees to the vertical. Also, the pivot point will be elevated to a height of 1.5 feet, with a sling that is 1.5 feet long. The weight of the arm is projected to be 0.5 pounds, in order to maximize the distance of flight for the golf

    According to Chevedden et al., (2002) the Latin word for trebuchet was “ingenium” and those who designed, made and used them were called inginators. These early engineers kept modifying the trebuchet to increase the range and impact force. One of the improvements engineers made was varying the length of the sling ropes so the shot left the machine at a ? angle of 45 degrees to the vertical (shown in the figure above), which produces the longest trajectory (Chevedden et al.,

    The Trebuchet was a very advanced siege engine that was used in the middle ages, it helped destroy several castles. The Trebuchet is a type of catapult that was used as a siege engine in the middle ages. The Trebuchet is a highly advanced device in terms of its engineering and it was built by engineers with exceptional designing and building skills. The advanced engineering of the trebuchet allowed the trebuchet to “sling” rocks, soil etc. to a target, thus allowing the trebuchet to destroy and weaken the castles walls and defences. These points link back to the focal statement that the trebuchet is a very advanced siege engine

    The word trebuchet originated in France, but contrary to the name, the early siege weapon actually originated in China. The original trebuchet was made in 300BC. The trebuchet was made as a way to attack over enemy walls or fire at large groups of enemies running at the user. The Chinese had a design in which good ol’ fashion man power was used instead of a counter weight. There weren't very many advancements in the Chinese trebuchet besides the use of different woods. This trebuchet tended to be the least accurate out of all of the other models. This model is known as the traction trebuchet.

    The history of a trebuchet is long and complex seeing as civilizations have struggled to properly maintain records throughout time. The term trebuchet comes from the French word “trebucher”, which means “to throw over”, or “to fall”. The war machine was called “Ingemium” in England, called so as it was Latin for “ingenious”. This ancient form of the trebuchet is called a traction trebuchet. Instead of utilizing a weight and gravity as modern ones do, this structure required man power to pull the arm of down in order to then release a projectile. These projectiles would then incessantly bombard city and castle walls. The trebuchet would, over many years, come to dominate battlefields in the place of catapults and

    Even though all trebuchets were similar in design, they were all made up of different materials. Heavy lead weights or a pivoting ballast box were the counter weights on many of the medieval trebuchets. They would also use leather pouches as the sack and then build the frame and arm out of wood/trees. During the medieval times, countries new that building walls would slow down enemy troops. The only issues with this are that they would not be able to defend against the trebuchets that are throwing one ton stones. The trebuchets were able to lock in on accuracy by judging how far their max throw is and would then move it depending on need for more or less distance. The way the modern trebuchet is being used today is mostly for teaching purposes. Colleges have been using this to help students think outside the box and create new trebuchets that can throw huge missiles like a car. We have seen many new ideas and ways to make a modern trebuchet, but all of these trebuchets are based on a single blueprint that was made over 900 years ago. In conclusion, trebuchets can be dated back to the 12th century where they were used for military strategies to throw heavy

    Take your trebuchet to the designated area you are told. Place the looped end of the sling over the firing pin on the throwing arm you have made. Place your cork/ object being fired in the sling basket. Pull the cork and mesh basket down to the opposite end of the platform until the firing pin is just above the platform with the cork and sling resting on the cardboard platform. Make sure you are not around anyone and then release the cork and the sling basket. Measure the distance the cork traveled and record the distance.

    Throughout the years, there have been many different forms of weapons used by the military. One type of weaponry that has failed to be used in modern-day military is a catapult. Catapults are very useful, if there is not a desired accuracy only a general direction in mind. One catapult that has recently been built and destroyed is called, “The Whatever,” created in Mr. Kunz’s sixth period Physics class by Brandon Jones and Jenna Lund. The name of the catapult fits the varying accuracy of the catapult though through testing of the angle of release, angle of launch and the position in which the object that would be projected forward would set.

    The earliest model was the trebuchet. It started by using a large weight on one end of a pivoting arm. The arm was pulled back the missile was placed and then let go. The weight went down, the arm went, and the missile launched. The later model gained its power from a tightly wound skein of rope, hair, and skin. the skeins were twisted incredibly tight and then had a wooden arm up to sixty feet long placed in between them. The arm was pulled back using pulleys and rope, the missile was placed in the wood cup and then the arm was released. The arm sprang to a 90 degree angle where it was stopped by a large padded piece of wood. The arm was then brought back down and fired again.

    First the energy of conservation. The setting of the trebuchet before firing is shown in Fig 1. A heavy counterweight of mass (M) (contained in a large bucket) on the end of the short arm of a sturdy beam was raised to some height while a smaller mass (m) (the projectile), was positioned on the end of the longer arm near or on the ground. In practice the projectile was usually placed in a leather sling attached to the end of the longer arm. However for simplicity, we shall ignore the sling and compensate for this omission by increasing the assumed length of the beam on the projectile’s side. The counterweight was then allowed to fall so that the longer arm swung upward, the sling following, and the projectile was ultimately thrown from its container at some point near the top of the arc. The far end of the sling was attached to the arm by a rope in such a way that the release occurred at a launching angle near the optimum value ( most likely by repeated trials) for the launch height. The launching position is shown in fig.2 where we have assumed that the projectile is released at the moment the entire beam is vertical. In the figures: (a)=height of the pivot, (b)= length of the short arm, (c)= length of the long arm, while (v) and (V) are the velocities of (m) and (M), respectively, at the moment of launching.

    Projectile motion is the force that acts upon an object that is released or thrown into the air. Once the object is in the air, the object has two significant forces acting upon it at the time of release. These forces are also known as horizontal and vertical forces. These forces determine the flight path and are affected by gravity, air resistance, angle of release, speed of release, height of release and spin
