History

Which constraint necessitated steeper suspension bridge cable sags amongst the Inca bridges?

A)Greater material tensile limitations
B)Stronger transverse wind stability
C)Reduced construction labor availability
D)Decreased seismic oscillation damping

💡 Explanation

Inca suspension bridges utilized plant fiber cables, therefore material tensile limitations were a core constraint; steeper sags reduce tension via Force Resolution. Sag compensates for the lower tensile strength, rather than focusing on wind or damping, which would involve different structural mechanisms.
