I'm thinking of the world being spherical and so the car is bent somewhat where the two sides of the vehicle (at each axis, so to speak) connect to the ground. The force acts in the centre where a moment may be produced yet the car is not stationary and thus cannot be modeled as a beam. Hence resolving right gives something like F - mgsin90 = 0 which I cannot do anything with and thus is a useless observation. The bridge is hump-backed, hang on a minute, what the fuck does that mean? If its humped back then its like a camel, it'll launch the car into the sky. Whatever... radius of curvature is 153.4, so there's the curve where the road and car meet, wait a min I'll draw it... done. Right, centripetal force comes out at 1421 to the nearest whole number. Force of gravity I assume to be standard therefore 9.81. Just toyed around with that because I figured I'd be wrong and you'd smack me with a ruler. put mg then took it from the centriputal force and got the answer. Don't know how the fuck to explain it or how to imagine it but it works. Thank-you anyhow.
