← HistoryWhich mechanical risk increased when Mesopotamians utilized bronze saws for cutting limestone blocks?
A)Blade-material cold-welding incidence rate
B)Workpiece-induced abrasion failure speed✓
C)Crystal lattice dislocation concentration rate
D)Operator bone conduction resonance frequency
💡 Explanation
Faster workpiece abrasion results from the limestone’s abrasiveness degrading the relatively soft bronze during cutting, thus this increases abrasion failure, because saw's inherent material properties. Therefore, higher abrasion rather than cold welding or crystal defects, occurs in hard stones.
