Which risk increases when Inca rope bridge anchor stones shift?

💡 Explanation

A stone anchor shift initiates increased deck displacement via cable slackening, because Geometric Instability amplifies displacement under load, therefore collapse chance rises, rather than frequency shifts or uniform strength losses which distributes load across independent cables.
