Question

Problem 4 (10 pts). We consider the effect of the Coriolis force on railroads in the northern hemisphere. (You can verify that the effects are reversed in the southern hemisphere.) Determine the direction (parallel to the surface) of the Coriolis force on a train running (a) east, and (b) west. Only the direction is necessary, not a calculation of the magnitude. In each case, indicate which set of wheels (right or left) push on the rail, and which rail, north or south, pushes back on the train. We consider the standard rail wheel design where a flange on the inside of the wheel keeps the train on the rail. Request explanation if this is not a familiar concept. (c) Comment on how this result might effect the maintenance of track and wheels.
