The Roman military technology ranged from personal equipment and armament to deadly siege engines. [ They inherited almost all ancient weapons. While heavy‚ intricate armor was not uncommon (cataphracts)‚ the Romans perfected a relatively light‚ full torso armour made of segmented plates (lorica segmentata). This segmented armour provided good protection for vital areas‚ but did not cover as much of the body as lorica hamata or chainmail. The lorica segmentata provided better protection‚ but the

Ancient siege weapons Onager (siege weapon) 1. A round stone (often clay balls with combustible substance in them‚ which explode on impact and burst into flames) is put in the pouch and the arm is winched down. 2. The onager’s framework is made out of two beams from oak‚ which curve into humps. In the middle they have quite large holes in them‚ in which strong sinew ropes are stretched and twisted. A long arm is then inserted between the bundles of rope; at its end it has a pin and a pouch

The creation of the catapult was around the 3rd to 4th Century BC (A Brief). There were three main types of Catapults: The Ballista‚ Mangonel‚ and Trebuchet. They were constructed massively up to sixty feet and larger‚ in addition‚ they were made out of wood‚ rope‚ and other materials (History of Catapults). Catapults were used as a weapon to launch stones‚ missiles‚ and other objects during warfare (History of Catapults). They were used for centuries up until the invention of gunpowder and other

Discussion The results did not give enough accurate data‚ due to the ability of the catapult and the weights used‚ the point at which the projectile stopped being efficient was not evident. If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more

Catapults were one of the most terrorizing and powerful weapons of Ancient Greece and Rome. They were able to destroy enemy defense and turned sieges in favor of the offensor. They also operated with deadly precision and could fire massive boulders huge distances. (Foley and Soedel 5). Catapults were some of the biggest engineering marvel of Ancient times‚ and marked the first time many engineering and management techniques that we see today were used. And these new engineering practices let the

In addition‚ a catapult was to be implemented and built based on an

device to launch a marshmallow into a container. Catapults were first invented to hurl projectiles farther than any human could. They were effective as blockade weapons and vital on the battle fields (Alchin‚ 2012). The type of catapult used in this experiment is called a Mangonel catapult. Typical mangonels are powered by a torsion-type string‚ which is twisted when the catapult arm is pulled back. When the catapult is fired‚ the spring pulls the catapult arm back to its original position‚ launching

Catapult Essay In the catapult project Joey’s group decided to try and make a ballista for there catapult project even though it wasn’t a catapult. Joeys group worked on the ballista for the first class but didn’t really know how to build it and didn’t have enough time to try and figure the problems out so we decided to build a catapult.then the next class Joey’s group took apart the ballista and started on the catapult.The purpose of this project was to be able to problem solve the problems your

Throughout the beginning of time‚ there was never an effective way to get aircraft’s properly off an aircraft carrier. That’s until the catapult came about‚ which paved the way to a safer lift off. The catapult improved the way the U.S. Navy prepared aircraft’s with bombs and machinery so they could fly to attack enemy forces. An aircraft catapult is a mechanism used to launch aircraft’s from ships‚ most commonly used on aircraft carriers‚ as a form of assisted lift off. It consists of a track built

The goal of our project was to launch a marble as accurately as possible and to calculate the initial velocity and angle of the catapult. In the beginning when we began testing‚ we had to find a way to keep our data stable and accurate‚ but that was a bit hard because the amount of force put onto the catapult differs at each trial and also did the angle of flight. Overall‚ I would say that‚ our data were accurate in trials 1‚2 and 4‚ but not 3 because I that trial‚ we used a bit more force to launch
