How much should the outer rail be raised above the inner one at the curve of the railway track so that the lateral pressure on the wheel flanges (the protruding part of the wheel rim that protects it from derailment) is equal to zero, if the radius of the curve is R = 800 m, train speed v = 72 km/h? Consider the width l of the railway track to be 1.5 m.
