← HistoryIn pietra dura of Mughal architecture, which failure in marble panels results owing to differential rates of thermal expansion?
A)Detachment of the assembled inlay✓
B)Increased compressive stress within
C)Undetectable shift over centuries
D)Uniform expansion with surrounding stone
💡 Explanation
Detachment of assembled pietra dura inlay occurs; differential thermal expansion generates internal shear stress exceeding bonding strength. This is because each material expands at different rates, therefore adhesive fails, rather than uniform movement observed in monolithic materials.
