Question

steering and suspension - final exam this exam consists of 25 questions. answer each question. \sprung mass\ is any mass that: is supported via a spring. does not follow bumps in the road directly. follows bumps in the road directly. moves when the suspension compresses or extends.

Explanation:

To determine the correct descriptions of "sprung mass":

1. Is supported via a spring: Sprung mass is the part of a vehicle's mass supported by the suspension springs (like the body, engine, etc.), so this is correct.
2. Does not follow bumps in the road directly: The sprung mass is isolated from road bumps by the suspension, so it doesn't follow bumps directly (the unsprung mass, like wheels, does). This is correct.
3. Follows bumps in the road directly: This is incorrect because the unsprung mass (not sprung) follows road bumps directly.
4. Moves when the suspension compresses or extends: As the suspension moves (compresses/extends) to absorb road impacts, the sprung mass (supported by the suspension) moves with it. This is correct.

Answer:

• Is supported via a spring.
• Does not follow bumps in the road directly.
• Moves when the suspension compresses or extends.
