Which risk increases when medieval rope bridges iced over?

💡 Explanation

Rope fiber strength declines occurs because materials exhibit decreased tensile strength at low temperatures. The individual fibers become brittle when frozen; therefore the likelihood of catastrophic bridge failure increases during higher loads, rather than the effects of anchors or cable strain.
