Which increased risk resulted from improperly annealed Roman siege engine springs?

💡 Explanation

Improper annealing leads to increased brittleness in the springs causing catastrophic brittle fracture during operation because fatigue crack propagation is greatly accelerated. Therefore, arm fracture increases, rather than rope slippage or missing targets, which result from different issues.
