A train has to negotiate a curve of radius. By how much should the outer rail be raised with respect to the inner rail for a speed of. The distance between the rail is .
Step 1: Given data
Radius of curve (R) =
Speed (v) =
Let the angle of banking be .
Step 2: Formula used and calculation of height
We know that for the banking angle.
, where is the acceleration due to gravity.
Hence, the outer rail must be raised to .
