A railway track is banked for a speed ' v ' by elevating outer rail by a height ' h ' above the inner rail. The distance between two rails is ' d ' then the radius of curvature of track is ( g = gravitational acceleration)
Options
- Av ^2 ~d gh
- B2 v ^2 gdh
- Cg d 2 v^2 h
- Dv^2 2 g h d
Correct answer
A. v ^2 ~d gh
Step-by-step solution
From figure, array ll & = h d & v ^2 rg = h d . ( = v ^2 rg ) & r = v ^2 ~d gh array
