RM2CH2E0A–. The Street railway journal . he mean accelerating efifort in pounds per motor during the speed interval V.W = the total dead weight of the train in pounds divided by the number of motors on the train.W i = the weight in pounds per motor that is equivalent in effect to the added resistance to acceleration due to the inertia of the rotating parts.This is usually equal to about 3 to 8 per cent of W.This formula can be set on the sliderule so as to read directly the value of tfor different values of A. V is best parts, therefore t = 22.5 seconds. This determines thefirst point of the curve (P, F
