A catapult is called a siege weapon for during medieval times it was used on sieges against castle walls or destroying any time for fortification. For a catapult to be considered a ‘real catapult’ it would have to be significantly large for any single person to carry.
The Catapult's History
A Catapult is a siege weapon developed by a Greek man called Dionysius the Elder of Syracuse around about 400 BCE. The earliest writing of catapults was in China around the 3rd and 4th century.
From Dionysius’s time evolved two types of catapults. First a two-armed catapult called the ballista. Unlike the normal one-armed catapult which hurls rocks; the ballista fires arrow or projectiles with great amounts force over a long distance.
Catapults become obsolete
Catapults had become ineffective in warfare in about 885-886 AD because of new advances in defense. Catapults had spent too much time to reload and relocate. It always required more than a single person to do anything with a catapult. Cannons replaced catapults as to being more effective and efficient. Cannons can be reloaded by a single man, and moving cannon would take far less time. Basically, when gunpowder was invented by the Chinese in the 11th Century catapults became obsolete.
Types of Catapults
The There are several types of existing catapults, however, there are four main types of catapults: There are several types of existing catapults, however, there are four main types of catapults: mangonel, trebuchet, onager, ballista.
The mangonel catapult is a military device used to throw missiles. It had a 'bucket' attatched to a platform and spring. The mangonel releases it’s item with torsion power/force- a force created using a twisting object- and stops when the plunger hits the slap/piece of wood in front of it.
The trebuchet is a more gravity-powered catapult. Most trebuchets are on wheels and have a sling- for the object/ball- and counter weight (usually a bucket). One side of the trebuchet is where the object you are aiming is in a sling, the other side is where the counter weight is going to be dropped into/onto a bucket/platform. Once the counter weight is dropped suddenly, the force of gravity allows the object in the sling to travel.
An onager is similar to the mangonel catapult- almost a mix of them both. The main difference is that the onager usually has a sling instead of a bucket/spoon. The onager is torsion powered and is stopped by a narrow wooden slab (like the mangonel), but also uses a sling (like the trebuchet).
The ballista catapult is the catapult that developed into a gun, it's design is similar to the crossbow design. The ballista is torsion powered- it uses a sort of elastic material (rubber bands) to launch the object in the directed direction given by the user. catapult is the catapult that developed into a gun.

What has become of You
The Mangonel Catapult
Why choose an Mangonel? We decided to build a Mangonel catapult because we believed that this type of catapult has the potential to throw a projectile an incredible distance. Using the tension of bands attached to both the crossbar and the base, a mangonel can fire objects with an incredible force. This coupled with the mangonels simplistic design made the decision of what to use very easy.

Mohamed buys structural pieces for Mangonel.
May 3, 2017
Osman and Mohamed construct main structure for the Mangonel. Base was created and support was also created
May 4, 2017
Mohamed adds crossbar and drills holes for the later installment of the arm.
We choose to rebuild the catapult on account of its small size and significant lack of proper stability. The change helped and made the catapult alot more powerful than its original design
May 7-10, 2017
Michelle and Jack rebuild same design. Larger base was created and support was also created. Crossbar and arm were installed, and the catapult's main power-the twine passing through the arm-was installed along with black string for lift support. The arm is being kept down by a metal rod passing through it towards the end of the catapult.
May 16, 2017
Osman and Mohamed add secondary source of power to catapult because lift power is not enough. Thick rubber bands have been stapled to the crossbar and arm for more power
May, 21, 2017
Jack and Michelle tie a few thick rubber-bands and staple them from the arm to the main structure as too increase force exerted from the arm
