what is the correct definition of unsprung mass?
mass of the springs.
mass that follows bumps in the road surface.
mass that is rotating.
mass that does not follow the bumps in the road surface.

Explanation:

To determine the correct definition of unsprung mass, we analyze each option:

• "Mass of the springs" is incorrect as unsprung mass isn't just the mass of springs.
• "Mass that follows bumps in the road surface" is correct. Unsprung mass (like wheels, tires, brake components) moves with road irregularities.
• "Mass that is rotating" is incorrect as rotation isn't the defining characteristic of unsprung mass.
• "Mass that does not follow the bumps in the road surface" is incorrect; that describes sprung mass (supported by springs, like the vehicle body).

Answer:

B. Mass that follows bumps in the road surface (assuming the option numbering, but based on the correct definition, the correct option is the one stating "Mass that follows bumps in the road surface")
