Question

The radius of a horizontal circular curve is 480 m and design speed there is 70 kmph. What will be the equilibrium superelevation for the pressures on the inner and the outer wheels to be equal ?

Answer 1

Equilibrium superelevation

$e=\frac{V^2}{127R}=\frac{{70}^2}{127\times 480}$

= 0.08 i.e., 8 %
