Question

A train rounds an unbanked circular bend of radius 50 m at a speed of 54 km h–1. If g = 10 ms–2, the angle of banking required to prevent wearing out of rails is given by

Solution

Correct option is

 

Now v = 54 km h–1 = 15 ms–1R = 50 m. the required angle of banking is given by

         

                  

                  = 0.45
