70% to passWhich of the listed reduction gear sets has the input and output shafts in-line with one another?
AParallel axis gearing
BBevel gearing
CWorm gearing
DEpicyclic gearing
AI Explanation
The correct answer is D) Epicyclic gearing. In epicyclic gearing, the input and output shafts are in-line with one another. This configuration allows for a compact design and efficient power transmission. The planetary gears within the epicyclic system rotate around a central sun gear, enabling the input and output shafts to be coaxial. The other options are not correct because: A) Parallel axis gearing has the input and output shafts offset from each other, B) Bevel gearing has the input and output shafts intersecting at an angle, and C) Worm gearing has the input and output shafts at a 90-degree angle to each other.
