Super elevation is inversely proportional to the radius.

E!=e B where e is the super-elevation.

No @Mr. Prasanna,

Total super elevation = e*W.

Where e - rate of SE.

W - Width of pavement.

It is directly proportionel to quare of velocity not directly proportionl to single velocity.

A is correct because velocity of vehicle is directly proportional to super elevation.

Rudresh meena said:   8 years ago
A is correct because velocity of vehicle is directly proportional to super elevation.

Rudresh meena said:   8 years ago
A is correct because velocity of vehicle is directly proportional to super elevation.

I think answer should be option (a), because question asking for incorrect statement.

Directly proportional to velocity square I guess that's why it's incorrect here!

e is directly proportional to v^2 and also inversely proportional to R.

Is it they are considering directly proportional to square of velocity?
