elocity until it stops. If r is greater than the grade of repose for the moving train, the velocity of the train as a whole will increase until the grade of repose has risen to r, when the velocity will remain constant, or r changes. If the locomotive is at zvork while running down the grade, all… … tension will be the least. As far as velocity is concerned, the effect of the locomotive working in running over any grade is just the same as thdugh r were increased if r is a minus or a down grade, and decreased if r is a plus or an up grade. The amount of this increase or decrease is practically…
