Concept explainers
To identify: Whether the friction between tire and road will increase by wide tire or not.
Answer to Problem 68A
No, the friction between tire and road will not increase by wide tire. It will remain same for wide tire as well as for narrow tire.
Explanation of Solution
Introduction:
Friction:
It is a contact force which acts between two surfaces. When two surfaces try to slide or slides across each other, friction force generates.
Friction does not depend on the surface area of tire.
Since,
The above equation shows that friction force depends on coefficient of friction
Hence, there will be no difference in friction of narrow or wider tires with the road.
