The Experiment
This experiment is to determine what projectile for a Ballista will travel the furthest, to do this two variables will be changed through the duration of the testing period. These variables are: the angle and the different materials the projectile is made of. The three different materials being used for the projectiles are a pencil, a bit of wood and a replica of an original Ballista bolt. The Results of this experiment is hypothesised that the replica Ballista bolt will have the most range of the three.

Ballista Basic Information
A Ballista was one of the siege engines used during the Medieval Era and was an invaluable siege attack weapon. The Ballista was used by both the attackers and defenders as an effective anti-personal weapon. For defenders the positioning upon the walls of a fortification would afford additional range to the weapon, and some were placed on pivoting frames to allow for quickly repositioning a shot. For attackers, the Ballista was sometimes a wagon mounted carro-ballista, allowing it great mobility in the field.

History of a Ballista
The Ballista's history dates back to antiquity. The Ballista is believed to be an ancient war engine which was invented by the Greeks and modified by the Romans in 400BC. The Ballista

The ballista was a Roman weapon, however the Greeks made the original design (which was named the scorpion), and the Romans later modified it. It looks like a giant crossbow, and that is, essentially, what it is. To load it, you winch the bow string back and set the tension. Load the ammunition, which is generally darts and spears and the string been unhooked, if you will, launches the projectile along a guided tube with deadly force and…

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 and their relatives were used both in ancient and medieval times in large numbers, and to their users utter enjoyment, and they remained effective for ages, despite an opponent's usually inefficient ways of trying to impede the seige weapons progress. However, the catapult is not really thought of. Not many people know what a ballista, an onager, or a spingold is. So in this essay, you're going to get the ins-and-outs of the catapult, its different types, its used, both in ancient, medieval, and modern-times, and the designs.…

The Medieval Ballista was a crossbow like weapon used during siege warfare. The word Ballista comes from the Greek word “Ballistes” which means “to throw”. The Ballista was a valuable siege attack weapon. The Ballista worked by using tension. It was designed to fire huge wooden, iron clad, darts or arrows which were powered by coils of hair, rope, or sinew. The tension in the coils helps launch the projectiles with enough force to give them great penetration through enemy walls or people. Ballista’s could be used both on offense or defense. The Ballista is thought to be a war device first invented by the Greeks and then improved by the Romans. During the Medieval era the Ballista reached Europe and was used by the French. During the siege of…

Most were based loosely on the ballista, a large siege weapon. A crossbow could be loaded for hours, and was able to be ready at all times, keeping the crossbowman from be- ing taken by surprise. The disadvantage, of course, was that it took quite a while to reload." (Medieval Weapons) Page 2 Unlike the bows and crossbows that were long distance weapons, axes of the Renaissance were the favored weapon of men-at-arms fight- ing on foot.

The Mangonel was invented by the Romans in 400 BC. The Mangonel consists of a long wood arm with a bucket with a rope attached to the end. The arm is then pulled back then the energy was stored in the tension of the rope and the arm. Then the bucket would be loaded. When the arm would be released the arm would return to its equilibrium position when it hit the beam.…

In medieval times catapults were used as siege weapons to capture castles and fortified walled cities. The most widely used catapults were ballistas, springalds, mangonels, onagers, trebuchets, and couillards. Ballistas were similar to giant crossbows and shot giant arrows. Springalds design was similar to a ballistas but it was more compact in order to be used in smaller spaces. Mangonels were designed to throw large objects such as boulders from a large bowl-like buckets at the end of its arm. Onagers launched projectiles from a sling which was later changed into a bucket and thus became a mangonel. Trebuchets were probably the most powerful catapult used in the Middle Ages. The ammunition used was often be stones, but darts or sharp wooden poles would sometimes be used as a substitute. Couillards were basically a simplified trebuchet but the counterweight was split swinging on either side of a central support post.…
