What collapse mechanism most likely explains the failure of some early Viking rope bridges in fjord crossings?

💡 Explanation

Material creep in hemp ropes causes elongated strain under constant loads, accumulating over time; therefore the bridge sags and eventually collapses, rather than experiencing resonance or wind oscillation common in rigid bridge types.

• Which critical ship failure increased as Viking longship rudder ropes stretched?
• Within the Byzantine navy, which consequence results when pre-ignited Greek fire encounters turbulent headwind conditions at sea?
• Which risk increased for Roman fortresses when using wood palisades?
• Around Mughal-era gardens, which result occurs because of reduced cross-sectional area pipes?
• Which risk to the structural integrity of ziggurats increased when seasonal flooding altered a region's clay composition?
• Which outcome results when uneven rates during shrinkage occur during the sand casting of Song Dynasty iron agricultural tools?
