Which mechanical consequence results when a crankshaft experiences torsional resonance in an internal combustion engine?

💡 Explanation

When a crankshaft experiences torsional resonance, increased cyclic stress occurs because the oscillations amplify, exceeding the material's fatigue limit and causing crack propagation. Therefore, fatigue failure results, rather than bearing damage, piston seizure, or valve float, which arise from lubrication, temperature, or timing issues respectively.
