← HistoryWhich outcome results from diminished torsion spring efficiency in a medieval trebuchet?
A)Reduced projectile kinetic energy transfer✓
B)Shorter recovery after projectile launch
C)Increased frame stress concentration overall
D)Elevated counterweight potential stability
💡 Explanation
Diminished trebuchet torsion reduces elastic potential, so less rotational kinetic energy translates to the projectile via angular momentum transfer, because the potential energy is lower. Therefore, projectile range is reduced, rather than alterations in recovery or frame loading which depend largely independently on the main frame elasticity.
