In the case of gyroscopic effect, the planes of spin, gyroscopic couple and precession are
- A. In same plane
- B. In different planes
- C. Any two in perpendicular planes and third in different plane
- D. Mutually perpendicular
Answer: D. Mutually perpendicular
Explanation: To achieve the effective gyroscopic effect, the planes of spin, gyroscopic couple and axis of precession are mutually perpendicular to each other.
