← HistoryWhich limitation affected suspension bridge lengths historically when using hemp ropes?
A)Rope tensile strength's low margin✓
B)Susceptibility increased to avian predation
C)Temperature coefficient instability emerged
D)Material costs limited total volume
💡 Explanation
Maximum bridge length reduced because hemp ropes had lower tensile strength, limiting span due to **tensile stress**, therefore rope bridges were shorter, rather than issues arising from temperature or other environmental factors.
