Stone Throwing Engine

Stone Throwing Engine is a form of Technology and Culture.

Description
An engine can be devised to throw rocks and stones over long distances. It can be used to bombard enemy soldiers, or break down light fortifications. It uses a long bamboo pole balanced on a supporting frame. One end is placed on the ground with a sling or basket to contain a rock to be thrown, while the other end is supported high in the air by the frame. Men pull down on ropes attached to the high end, causing the low end to pivot up and fling the rocks.
