Question -
Answer -
Radius of the circular track, r =30 m
Speed of the train, v = 54km/h = 15 m/s
Mass of the train, m = 106 kg
Thecentripetal force is provided by the lateral thrust of the rail on the wheel.As per Newton’s third law of motion, the wheel exerts an equal and oppositeforce on the rail. This reaction force is responsible for the wear and rear ofthe rail
The angle of banking θ, isrelated to the radius (r) and speed (v) by the relation:
Therefore,the angle of banking is about 36.87°.
