Which risk increased significantly during winter when pedestrians traversed Incan rope suspension bridges?

💡 Explanation

Low temperatures caused cable materials to become brittle reducing tensile strength due to thermal contraction; because the yield strength decreased, brittle breaking was dominant on stressed cable strands, therefore early bridge failures, rather than suspension efficiencies, influenced replacement schedules.
