A meter gauge railway track is to be banked at a circular curve of a radius 450m. What should be the elevation of the outer rail above the inner rail for an optimum speed at 54km/h, So that there is no side thrust on the outer rail.

A car is moving along a banked road laid out as a circle of radius r . (a) What should be the banking angle theta so that the car travelling at speed v needs no frictional force from tyres to negotiate the turn ? (b) The coefficient of friction between tyres and road are mu_(s) = 0.9 and mu_(k) = 0.8 . At what maximum speed can a car enter the curve without sliding toward the top edge of the banked turn ?
