Two cars are identical, except for the type of tread design on their tires. The cars are driven at the same speed and enter the same unbanked horizontal turn. Car A cannot negotiate the turn, but car B can. Which tread design yields a larger coefficient of static friction between the tires and the road?


a) tread design on car A


b) tread design on car B


c) coefficient of static friction is equal for both the tread designs

Agreed on Car B

Mr. 007 is wrong. it asks for the larger coefficient of static friction of the tread DESIGN, not of the material.
Reply:Physics Geek is Right. B is the answer.
Reply:Car B.





lower friction is the cause for understeer of car A.
Reply:coefficient of static friction is same. with identical cars means the weight is same. u=f/r.


u is independent it is dependent on nature of the material.
