← HistoryWhich outcome arises when repeated rapid firing overheats a repeating crossbow's bronze arrow magazine in Han Dynasty?
A)Reduced string tensile strength
B)Deformation impairs arrow feed✓
C)Trigger mechanism malfunctions
D)Fractured cast iron components
💡 Explanation
Rapid firing causes thermal expansion in the bronze magazine, leading to deformation because differential heating changes the material's dimensions, therefore creating feeding problems rather than string issues, trigger failure, or breakage of cast iron, which not part of the magazine.
