Ballista

Have you ever wondered how a catapult works? We had to ask just that question when we were assigned a project. Where we had to create a functional catapult and graph the arc of the object shot from the catapult we created. In this essay I will discuss the history and mathematical concepts behind catapults. I will also include some fun facts. There are many mathematical concepts behind a catapult. One big mathematical concept behind a catapult is a parabola. A parabola is defined as “a symmetrical

Do you know how a catapult works? It uses a weight or tension. According to research, you need a projectile lighter than the weight to launch the projectile. If the weight is too light it won’t launch the projectile. To see if if it’s heavy enough, you can weigh it. What is a catapult you might ask… Well, a catapult launches a projectile from one place to another, from the weight/tension of the rubber band or weight of metal that’s going to make the object get pulled from the weight of the object

First in the design process was developing the concept solutions. The Catapult and the Side Catapult (II & III in Fig. 1) were a classic design that had potential to be modified with a string pull trigger. The Spinner and the Shooter (I & IV in Fig.1) resembled the design of toys that shoot a foam disc similar the competition projectile. Our Datum for the decision matrix (VI in Fig.1) is a ramp with a spring-loaded striker to propel the disc. The Pin model is a hybrid of the Shooter and the Datum

Hypothesis A catapult build using hot glue will have the strongest hold. Background Information While doing research of what exactly a catapult is. I learned a catapult is a machine also known as a lever that has been used for hundreds of years. Which, really means that we have used physic for a long time. The base on the opposite ends of the cup the fulcrum. When the action of pulling back where the cup you are creating built up potential energy. However, when the cup is release kinetic energy

Catapults were ballistic devices. It was invented by a man named “Dionysius the Elder” and created it around 400 BCE. Since then it was a key weapon in warfare. The way it works is that a piece of wood called the arm was connected to a cup shaped bowl but another name for it was a bucket. The bucket was meant for holding the object you wanted to launch. The objects people decided to launch whatever it was it was called the payload. The arm connected to the bucket is laid flat down and springs vertically

The problem that our catapult solves is that it launches object without the use of relatively dangerous elements, like fire and gas. Also catapults solve the dilemma of a achy shoulders, because without a catapult one would need to go out of their way to launch something. But with a catapult they simple need to pull back the spoon to create energy.

One of Rome’s greatest inventions were the siege weapons, The siege weapons were used to help break through city fortifications and for providing cover for soldiers. The Romans invented countless types of siege weapons. One of the most known is the Ballista and the original Battering Ram, Alexander the Great was one of the first leaders to use siege weapons in his army. While the siege weapons helped they were heavy to move and reloaded very slowly after every shot but it caused massive damage on cites

It was also a better weapon than the ballista, as the catapult was portable with it's wheels.Torsion powered catapults such as the ballista used cranks to pull back the basket that held the projectile. Torsion was a form of power created when the rope of the Ballista was twisted to generate the force. The rope would get tighter and when released, the force would propel the projectile forward from the

The Roman army was the most powerful war machine of its time and arguably many others. It is this vast war machine that facilitated the Roman Empire and its creation. I call the Roman army a war machine because of the meticulous organization the army displayed, organization so thorough it mimics the individual cogs and gears in a machine working in perfect unison to achieve a common goal. The roman army was responsible for developing revolutionary fighting techniques which not only secured Rome’s

different, but there were three main types, which are Ballista, Mangonel, and Trebuchet.
