Q1:

If Δ is the angle of deflection of a simple curve of radius R, the distance between the mid-point of the curve and long chord, is

A

B

C

D .

ANS:D - .

As we have radius R so distance from centre to mid point of long chord is R cos Δ/2 So,
Therefore distance from mid-point of the long chord to mid of curve is R - R cos Δ/2.
