Which outcome results when exceeding the turbine blade's creep limit in a jet engine?

A)Decreased compressor stall margin results
B)Uncontrolled increase in blade resonance develops
C)Progressive elongation and deformation occur
D)Sudden embrittlement and fracture happen

💡 Explanation

Exceeding a jet turbine's creep limit leads to progressive deformation because creep is temperature and stress-dependent plastic deformation; therefore, the blades elongate and deform rather than embrittle, since resonance or stall isn't directly caused this failure.
