← HistoryWhich outcome occurs when a Viking longship's sail experiences unequal wind forces?
A)Increased yaw instability✓
B)Reduced hull stress
C)Decreased turning radius
D)Enhanced forward speed
💡 Explanation
Increased yaw results from Torque Imbalance because unequal force on the sail creates a turning moment. This force causes the ship to turn unintentionally rather than maintaining its heading; therefore, directional instability increases rather than any enhancement of speed or reduction in hull stress.
