← HistoryWhich consequence results when repeated use of chronometers on ships induces material changes?
A)Spring fatigue alters rate accuracy✓
B)Gimbal lock seizes internal gears
C)Thermal variation halts balance wheel
D)Hygroscopic dampening swells pivots
💡 Explanation
Spring fatigue of delicate components leads to changes because cyclical stress weakens metal, allowing it to slowly deform under continued load; therefore the rate accuracy suffers unpredictably rather than a sudden catastrophic failure of the movement at sea.
