When the pinion gear is driven by the _____ and the _____, the yaw bearing rotates the nacelle.

Explanation:
The yaw system moves the nacelle around the turbine’s vertical axis using a pinion and a large ring gear. A yaw motor powers a yaw drive gearbox, and that drive turns the pinion gear. As the pinion rotates, it mesh with the yaw ring gear fixed to the nacelle, causing the nacelle to rotate on the yaw bearing to face the wind. This is why the combination of the yaw motor and the yaw drive is the correct mechanism for driving the pinion and rotating the nacelle.
