According IRC : The super-elevation is calculated for 75% of design speed.
So e = V^2/225R.
So e = V^2/225R.

Design speed is given use: e = (0.75v)^2/gR.
In a question if they are given only speed then use: e = v^2/gR.
In a question if they are given only speed then use: e = v^2/gR.

Guys can you please tell me the density of GSB, WMM, DBM and also BC?

ANS (A).
e = V^2/225R.
e = 0.025 = 1 in 40.
e = V^2/225R.
e = 0.025 = 1 in 40.

e = v^2/(127R) this formulas use.
And get the super elevation.
And get the super elevation.

Radius is not mentioned.

F = 0 V = 0.75 V design speed.
E = (0.75 V)^2/(127 R).
E = (0.75 V)^2/(127 R).

1000 m is length of curve here, not radius.

1000 m is radius, it can't be length because there is no relation to provide length.

But we have studied it in the formula = v^2/126R. I am confusing which one is correct.
