← HistoryWhich mechanism causes reduced longship stability when its cargo shifts during ocean travel?
A)Metacentric height reduction✓
B)Keel warp instability
C)Hull resonance amplification
D)Rudder turbulence induction
💡 Explanation
A shifting cargo alters the center of gravity, decreasing the metacentric height because the restoring moment arm is reduced. Therefore, the longship becomes less stable, rather than experiencing keel warp, resonance, or rudder turbulence, which are caused by forces other then weight distribution.
