Which material behavior posed the greatest limitation to Song Dynasty iron suspension bridge construction?

💡 Explanation

Yield strength was critical because exceeding it causes permanent deformation under load rather than fracture immediately; therefore, the cables would droop over time because exceeding the elastic limit from creep would reduce their effectiveness, rather than outright breaking them.
