← HistoryWhich outcome occurs when the peat moor shifts unevenly beneath a Viking-era rope bridge?
A)Increased lateral component of tension✓
B)Decreased catenary curve uniformity
C)Reduced timber susceptibility to rot
D)Elevated resistance to aeolian vibration
💡 Explanation
Increased lateral tension develops because differential settling causes unequal force distribution within the bridge structure; therefore, the bridge twists under load, rather than deforming uniformly, because tension seeks equilibrium on changing supports.
