← HistoryWhich risk increased as Viking longships used increasingly longer rigging?
A)Increased probability of rope slippage✓
B)Greater material thermal expansion stress
C)Decreased keel laminate shear forces
D)Reduced likelihood of sail chafing
💡 Explanation
Rope made of organic materials is subject to creep, therefore greater overall length of rope results in increased elastic deformation under tension over time because rope slippage increases with length and cumulative stress, rather than thermal expansion which is minimal.
