Diagram for question 127
AI Explanation
The correct answer is B) synchronous transmission. The synchronous transmission is the mechanism used to transmit the rudder angle information from the steering gear to the wheelhouse in the illustrated rudder angle indicator system. This type of transmission ensures that the rudder angle indicator in the wheelhouse accurately reflects the actual position of the rudder, allowing the ship's captain to monitor and control the vessel's steering. The other options are incorrect because: A) a telemotor is a hydraulic system used to transmit steering commands, not angle information; C) a differential gear is used to combine or split mechanical power, not transmit angle data; and D) a gear transmission is a general term that does not specifically describe the mechanism for transmitting rudder angle.
