The wheels of a train, engine as well as bogies, are slightly tapered to_____________?
Correct answer: D. facilitate in taking turns
- A. reduce friction
- B. increase friction
- C. facilitate braking
- D. facilitate in taking turns
Explanation
Tapered railway wheels help the wheelset develop different effective rolling radii on the two rails while negotiating a curve. This allows the train to take turns smoothly without requiring separate axle speeds.
