I am teaching myself physics using Giancoli's ed 5 text, and am confused on one of the examples. P 121 in the fifth edition, example 5-8 to be precise. In this a car is on an inclined plane (i.e a racetrack where the road banks to reduce the friction needed to keep the cars on the track). The solution explains that the normal force perpindicular to the track is greater than the force due to gravity directed downward. In previous examples, gravity was generally resolved into two components, but in this example it seems the normal force is resolved into two components, with the vertical component of the normal force set equal to gravity. This seems incorrect, what am I missing? Thanks
