Mechanical weapons are devices designed to inflict damage or harm using mechanical principles rather than chemical reactions. Examples include catapults, crossbows, and ballistae, which rely on tension, torsion, or gravity to launch projectiles. These weapons have been used throughout history in warfare and hunting. The effectiveness of mechanical weapons often depends on their design and the materials used. They can be operated manually or with the help of simple machines, making them accessible to various cultures. Mechanical weapons played a significant role in shaping military strategies before the advent of modern firearms.
