← HistoryWhich consequence results when severe icing altered the sail's curvature on a Viking longship?
A)Reduced hull's wave-piercing efficiency
B)Altered center of effort significantly✓
C)Induced catastrophic mast shear failure
D)Increased frictional drag drastically
💡 Explanation
A severe change in the sail's shape due to icing shifts the center of effort because mass distribution changes, leading to unbalanced forces acting on the ship. Therefore, the longship becomes harder to handle, rather than immediate mast failure since sails are flexible.
