The design speed of a highway is 70 km/h. There is a horizontal curve of radius 160 m on a certain locality. The safe limit of transverse coefficient of friction is 0.15. (i) If the maximum super-elevation of 0.07 is not to be exceeded, the maximum allowable speed on this curve will be (a) 70 km/h (b) 67 km/h (c) 64 km/h (d) 55 km/h (ii) For the pressure on inner and outer wheels to be equal, the equilibrium super-elevation rate can be given by (a) 1 in 10 (c) 1 in 5 (b) 1 in 6 (d) 1 in 4
