On a circular curve, the rate of super-elevation is e. While negotiating the curve a vehicle comes to a stop. It is seen that the stopped vehicle does not slide inwards (in the radial direction). The coefficient of side friction is f. Which of the following is true:
  • a)
    e ≤ f
  • b)
    f < e < 2f
  • c)
    e ≥ 2f
  • d)
    None of the above
Correct answer is option 'A'. Can you explain this answer?

For equilibrium
fN ≥ mg sin θ
⇒ fmg cos θ ≥ mg sin θ
⇒ fcos θ ≥ sin θ
⇒ f ≥ tan θ
