History

Which outcome results when wooden rope bridges experience significant water penetration during winter thaws in the Inca Empire?

A)Increased wind resistance due to stiffening
B)Cable sag increases structural instability
C)Improved load distribution within the ropes
D)Enhanced tensile strength of support cables

💡 Explanation

Bridge collapse will occur when cyclic freeze-thaw causes entrained water to expand within ropes, initiating internal cracks via ice wedging, because rope strength decreases significantly; therefore, the bridge sags dangerously, rather than gaining strength at low temperatures which would maintain stability.
