← HistoryWhich outcome occurred when the Viking longship sail's angle relative to the wind shifted adversely during a coastal raid?
A)Lateral drift significantly increased✓
B)Forward speed dramatically decreased
C)Mast structural fatigue accelerated rapidly
D)Leech line tension became irreversible
💡 Explanation
Increased lateral drift resulted from adverse sail angles because the aerodynamic force vector component shifted sideways according to Bernoulli's principle, rather than acting predominantly forward; therefore, the ship moved sideways more than forward, rather than maintaining its intended course.
