In the design of a Roman ballista, which limitation increases with increased projectile mass?

💡 Explanation

Increased projectile mass raises stress on the torsion mechanism; therefore, rope fiber fatigue increases more rapidly because sustained high tension will degrade before tensile stress exceeds the yield stress. This failure mode limits weapon lifespan, rather than transportability or frame strength.
