Question

A train is moving towards north. At one place it turns towards north-east, here we observe that

• A. The radius of curvature of outer rail will be greater than that of the inner rail
• B. The radius of the inner rail will be greater than that of the outer rail
• C. The radius of curvature of one of the rails will be greater
• D. The radius of curvature of the outer and inner rails will be the same

Answer 1

The correct option is A

The radius of curvature of outer rail will be greater than that of the inner rail

The radius of curvature of outer rail will be greater than that of the inner rail so as to facilitate the turn of the train.
