← HistoryWhich stability risk increases when ziggurat corners experience acute weathering?
A)Shear stress on load-bearing walls
B)Settlement due to compaction increase
C)Torsion from unbalanced moment✓
D)Resonance from increased wind force
💡 Explanation
Torsion increases, because corner erosion alters the center of mass location, enhancing the overturning moment via eccentric loading. Therefore, it elevates risk of a rotational structural failure, rather than compressive (settlement) or vibrational (resonance) problems.
