Which mechanical risk increased in Inca rope suspension bridges when the ichu grass anchors dried out?

💡 Explanation

Rope strength diminished because desiccation reduced fiber flexibility via material property changes resulting in eventual cable breaks. Therefore, tensile strength is the key concern, rather than plank shear or aerodynamic instability specific to more rigid structures.
