Which outcome occurs when a turbine's nacelle yaw gearbox experiences component fatigue?

💡 Explanation

Misalignment results because fatigue weakens the yaw gearbox's rotational accuracy about the vertical axis. This activates a closed loop feedback controller, which increases yaw angle error to reduce the performance, rather than maintaining an optimal angle.
