← HistoryWhich consequence results when repeated firing of a Han Dynasty automatic crossbow leads to structural changes in the bronze trigger mechanism?
A)Increased firing rate initially occurs
B)Creep causes dimensional inaccuracy✓
C)Complete corrosion failure takes over
D)Higher tensile triggers are yielded
💡 Explanation
Dimensional inaccuracy occurs because creep, the gradual deformation under sustained stress, introduces changes in the bronze trigger's precise dimensions. Therefore, accuracy degrades rather than rate, or corrosion effects because bronze is corrosion-resistant and properly heat may prevent quick yielding.
