← TechnologyWhich mechanism can result in catastrophic engine failure due to imbalanced diesel crankshaft loading?
A)Torsional resonance amplification✓
B)Hydraulic lock deformation
C)Connecting rod buckling
D)Thermal expansion seizing
💡 Explanation
Torsional resonance amplification initiates destructive vibrations in the crankshaft because fluctuating combustion loads and inertial forces align with the crankshaft's natural frequency, therefore leading to fatigue failure rather than simple overload or thermal stress.
