Springs absorb wheel jounce and rebound.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Springs in a vehicle's suspension system are designed to absorb the impact and vibrations caused by uneven road surfaces. When a wheel encounters a bump or pothole, the spring compresses, absorbing the jounce (upward movement) of the wheel. As the wheel moves back down, the spring expands, absorbing the rebound (downward movement) of the wheel. Therefore, it is true that springs absorb wheel jounce and rebound, helping to provide a smoother and more comfortable ride.Rate this question:
