Maths and geometry were also used to create tables of the correct proportions for parts of the catapult. For example, the weight and length of the projectile was proportional to the size of the torsion springs. Maths was involved as each part of the catapult was proportional to the size of the object it was designed to propel. And designers conducted experiments to optimise their construction. Geometry, physics, statistics, mechanics and pneumatics were used to design the catapults. When the catapult arm was pulled back and released, the twisted rope uncoiled forcing the arm forward and releasing the projectile. It was powered by springs made from tightly wound rope or animal sinew, said Cuomo. The torsion catapult was a more sophisticated design. These were made from an enlarged bow, placed on a stand, with winches used to pull back the arm and launch the projectile. Catapult shooting was one of the traditional Greek sports used to train the military.Īfter the belly bow came larger, stronger catapults that allowed bigger projectiles to be launched. The early Greek catapult was the 'belly bow' and, as its name suggests, consisted of a bow that rested on a person's belly. An army could use a single catapult for up to 20 years. "Until the invention of gunpowder, the catapult was the most powerful weapon," she said. Sophisticated catapults propelled stones as heavy as 80 kilograms into the air. Science historian Dr Serafina Cuomo from the U.K.'s Imperial College London published her report on this early use of science and technology in today's issue of the journal Science.Ĭuomo described how catapults were made as early as the 9th century BC to be used during war to launch arrows or stones at the enemy and their forts. The catapult makers also met colleagues in neighbouring countries to discuss their designs in the ancient equivalent of a scientific conference. People who made ancient catapults combined mathematics and engineering skills to create the most powerful weapons of their time, according to a new report. ![]() Soggy Balkan relics reveal ancient life, Science Online,.Burned barricades suggest origin of war, Science Online,.Medieval weapons of mass destruction, Science Online,.
