← HistoryWhich materials failure increases when a Roman ballista launches projectiles at maximum range?
A)Limb-material creep✓
B)Frame-member buckling
C)Rope-fiber tangling
D)Counterweight settling
💡 Explanation
Limb-material creep increases at maximum range because higher torsion generates prolonged stress levels, leading to gradual distortions of the composite materials used by Roman engineers. Therefore, creep is the main limit, rather than immediate fiber failure or instability.
