Q1:

Perpendicular offset from a tangent to the junction of a transition curve and circular curve is equal to

A shift

B twice the shift

C thrice the shift

D four times the shift.

ANS:D - four times the shift.

Shift of curve is l^2/6R which is 4 times of shift of the curve. L ^2\6R and formula of shift of curve is L^2 /24, So its four times of it. Here, the Distance is l^2/6R.
