← HistoryFor Viking rope bridges spanning ravines, which outcome occurred with high humidity?
A)Decreased rope tensile strength✓
B)Increased structural static stability
C)Reduced deck plank warping
D)Improved timber support durability
💡 Explanation
High humidity causes decreased tensile strength because moisture absorption leads to fiber weakening within the rope; therefore, rope failure risk increased, rather than having increased stability due to material properties of the organic materials forming the bridge.
