← ScienceWhich risk increases when attempting to operate a Carnot engine isothermally at speeds exceeding material limits?
A)Increased thermal boundary layer resistance
B)Reduced entropy generation during process
C)Increased component fatigue failure rate✓
D)Minimized exergy destruction within system
💡 Explanation
Increased speed leads to oscillations beyond the frequency response of the metal; this causes metal fatigue, because cyclic stress concentrations will undergo work hardening and thus accelerating material cracking, therefore fatigue elevates rather than decreasing entropy, and heat transfer.
