Q1: The ruling minimum radius of horizontal curve of a national highway in plain terrain for ruling design speed of 100 km/hour with e = 0.07 and f = 0.15 is close to

A 250 m

B 360 m

C 36 m

D 300 m

ANS:B - 360 m

V = 100km/hr = 100x (1000/3600) m/s = 27.78 m/s;

E+f = 0.07+0.15 = 0.22;
Now, R = V^2/g (e+f) m/s
= 27.78^2/ (9.81*0.22)
= 357.52 m/s say, 360 m/s.
