Question

The outer rail of a curved railway track generally raised over the inner. Why? ​

Answer 1

Answer:

The outer rail of a curved railway track is generally raised over the inner. Why? Answer: When the outer rail of a curved railway track is raised over the inner, the horizontal component of the normal reaction of the rails provides the necessary centripetal force for the train to enable it move along the curved path.

Answer 2

Answer:

This is because It reduces the horizontal component of the centripetal force. The reaction to the centripetal force (that is, the force on the train of the rails) would try and push the train off of the track on the outside of the bend. Raising the outside rail converts some of the horizontal component into vertical component which can be taken by the track.
