Q.43. The radius of curvature of meter gauge railway
line at a place where the train is moving with a
speed of 10 m/s is 50 m. If there is no side thrust
on the rails, find the elevation of the outer rail
above the inner rail.
Solution:​

Answer 1

Answer:

Nsinθ=

r

mv

2

Ncosθ=mg

tanθ=

rg

v

2

if we define h as the elevation,

1.5

h

=

1000×9.8

100

h=

98

1.5
