Which outcome most commonly resulted from the inherent limitations of the Roman ballista's torsion springs in sustained sieges?

💡 Explanation

Fiber stress relaxation in siege ballistae caused declining torsion over time, because energy storage decreased. Therefore firing range would eventually decline, rather than catastrophic structure and inconsistent projectiles, within operational constraints.

• Which outcome arises in early cast iron plowshares due to repeated soil impact?
• Which outcome arises in early post-Song Dynasty Chinese cast iron cannons when exceeding operational powder limits?
• Which outcome arises when pre-Columbian chinampa cultivators neglect the 'xochimolli' maintenance?
• Which limitation existed in early (pre-industrial) pietra dura stone inlay processes that constrained the precision of complex Mughal floral patterns?
• Which structural weakness arises when a Roman castrum wall's foundational drainage system fails due to silt accumulation?
• Which risk increases upon the failure of Viking longship's sail-reefing mechanism?
