If speed2 is less than speed1, the transmission angle will be

Explanation:
The transmission angle reflects how the drive can efficiently transfer motion and force between connected parts, and it changes with the velocity ratio between input and output. When speed2 is less than speed1, the velocity ratio is less than one, and the geometry of the drive shows a smaller angle for transmitting motion than in the equal-speed case. So, the transmission angle becomes smaller than its baseline (the value you’d have if speeds were equal). This is why the best choice is that the transmission angle is less than that baseline.
