← HistoryWhich outcome primarily occurred when laying elaborate pietra dura mosaics in Mughal buildings during seasonal ground shifts?
A)Improved hydrostatic pressure distribution
B)Localized mosaic fracturing arises✓
C)Enhanced thermal expansion regulation
D)Increased surface albedo reflection
💡 Explanation
Localized cracking occurred because differential ground settlement induced stress concentration. This strain bypasses the intended design because the tesserae experience bending stress in localized zones, therefore fracturing mosaics rather than even load management.
