Dear student,


When vehicle go through turnings, they travel along a nearly circular arc. There must be some force to produce the required centripetal acceleration. Centripetal force is provided to the vehicle by following three ways.





  • By friction only



  • By banking of roads only



  • By friction and banking of roads both.





1) By friction: 

    Let a car of mass m is moving at a speed v is at horizontal circular arc of radius r.    

   

And fL= limiting value of f = N = mg      (N=mg)
For a safe turn without sliding,



So if m and r is fixed the speed of the vehicle should not exceed and if v and r is fixed then coefficient of friction should be greater than
2) By banking of roads only.
