← HistoryWithin Incan rope bridges, which consequence follows prolonged environmental moisture exposure?
A)Material creep accelerates sharply✓
B)Cable tension directly increases
C)Static electricity hazard intensifies
D)Resonance frequency becomes stable
💡 Explanation
Accelerated material creep results as moisture weakens rope polymers because the amide bonds hydrolyze reducing load-bearing capacity; therefore creep rate rises with humidity, rather than structural stiffening or electrostatic effects under dry conditions.
