← HistoryWhich outcome predictably occurred when medieval rope bridges experienced sustained high humidity?
A)Decreased tensile strength of ropes✓
B)Increased bridge weight capacity
C)Amplified wind resistance
D)Improved static load distribution
💡 Explanation
Sustained high humidity increases moisture content in hemp ropes, causing a molecular weakening via hydrolysis; therefore, the tensile strength decreases catastophically, rather than experiencing increased capacity, optimized weight distribution, or greater wind resistance from this type of environmental degradation's weakening mechanism.
