Question
A passenger train has 21 bogies. Will the tension in the coupling between different bogies be the same?
Solution
The tension in coupling will not be the same for all the bogies. Tension is maximum in first coupling and minimum in the last coupling.
If the tension in the coupling for different bogies is the same, then there is a possibility that the bogies will collide.
