What do you call a medieval siege artillery that can hurl projectiles?

A medieval siege artillery that can hurl projectiles is commonly known as a "trebuchet." This powerful device uses a counterweight system to launch heavy projectiles, such as stones or incendiary materials, over castle walls or fortifications. Trebuchets were highly effective in siege warfare during the Middle Ages, capable of causing significant destruction to enemy defenses. Other types of siege engines include catapults and ballistae, but the trebuchet is particularly renowned for its range and accuracy.
