Which risk increases when excessive pressure is applied during Inca stone masonry?

💡 Explanation

Joint spalling increases with excessive pressure because it exceeds the stone's compressive strength, initiating crack propagation through the assembly; therefore damaging the structural integrity, rather than quipu, terrace, or aqueduct failure which involves unrelated mechanics.

• Which outcome regularly occurred in Incan terrace farming when poorly designed qochas (reservoirs) were placed above active terraced plots?
• Which outcome follows from timber decay weakening a motte-and-bailey castle?
• Which risk increased during long 18th-century sea voyages due to copper sheathing galvanic corrosion?
• During Inca empire administration, what happens when quipu literacy erodes within a region?
• Which limitation arises when using a brass astrolabe to measure stellar altitudes over decades in a coastal environment?
• Which consequence was faced by the Byzantine mosaic artists that impacted future restoration efforts when atmospheric pollutants interacted with the tesserae bedding?
