For a parallel axis single reduction gear, what statement is true?
AI Explanation
The correct answer is A.
In a parallel axis single reduction gear, the drive pinion is the smaller of the two gears and rotates at a relatively high speed. The driven gear is the larger of the two gears and rotates at a relatively low speed. This configuration allows the gear ratio to be reduced, transmitting the high-speed rotation of the drive pinion to the lower-speed rotation of the driven gear.
The other options are incorrect because they describe the opposite relationship between the drive pinion and driven gear sizes and rotational speeds, which would not be characteristic of a parallel axis single reduction gear.
