History

Which consequence resulted from creep in historic Inca rope bridges?

A)Reduced tensile strength of ropes
B)Increased bridge deck instability
C)Accelerated material oxidization rates
D)Elevated frictional contact resistance

💡 Explanation

Increased decking instability resulted from creep because rope fibers experienced continuous deformation under sustained tension, resulting in a lowered elastic modulus, therefore deck sagged over time, rather than an instantaneous breaking point or altered chemical properties.
