← HistoryWhich risk increased notably in 14th-century European siege warfare because of early cast-iron cannons employing insufficient barrel reinforcement?
A)Premature projectile trajectory deviation
B)Catastrophic barrel rupture upon firing✓
C)Elevated propellant deflagration rates
D)Accelerated trunnion fatigue cracking
💡 Explanation
Catastrophic barrel rupture was increasingly hazardous because early cast iron cannons relied on inconsistent metal quality where localized defects enabled rapid crack propagation through *brittle fracture*, therefore cannons violently exploded, rather than exhibiting ductile deformation or controlled venting as with later designs.
