(A) 0.38 N V3/2 (X)
(B) 0.38 (NV3)”2 ()
(C) 3.8 NV”2 (X)
(D) 3.8 (NV3)”2 (X)

Answers: If the design speed is V kmph and deviation angle is N radians, then the total length of a valley curve in meters is given by the expression  0.38 (NV3)”2.

(B) 64m (X)
(C) 80m (X)
(D) 60m ()

Answers: If an ascending gradient of 1 in 50 meets a descending gradient of 1 in 50, the length of summit curve for a stopping sight distance of 80 m will be 60m.
