Question

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

Answer 1

Hi..

Now v=54kmh−1=15ms−1
R=50m
The required angle of banking is given by
tanθ=v2Rg
=15×1550×10
=0.45...


Hope this helps u!!
