Question

The rolling resistance does not depend upon

• A. Velocity of the vehicle
• B. Density of air
• C. Construction of tyre
• D. Mass of the vehicle

Hint:

When optimizing vehicle efficiency, focus on tire pressure and tread patterns, which are significant factors affecting rolling resistance.

Answer 1

The Correct Option is B

Rolling resistance primarily depends on factors such as the tire's construction, the vehicle's mass, and its velocity, but not directly on the density of air. Air density impacts aerodynamic drag rather than rolling resistance.
