NOTES
Title from title frames
Delve into the history of the most potent artillery weapons in the era before gunpowder: catapults. Examine the workings of the ballista, onager, and trebuchet. Then get started on a model ballista capable of hurling a golf ball 200 feet. Analyze the machine's nylon torsion springs to ensure that they can store enough elastic energy to achieve the required 200-foot range
