neton at a steady speed on the level,and s the slope or gradient in parts per thousand; then the pull required on the level will be W .f. On the slope, the weightAB (Fig. 203) acting vertically downwards can be resolved into two com-ponents, one normal to the surface and the other AO, which has to… … The pull on the car must therefore be given by the formula F = W.f+ W.s= l^{/+s)kg*.If the radius of the car-wheels be r metre, the torque on the axles must^^ F.r=W{f+ s) .y met.-kg. If the gear is such that the motor runs k times as fast as the car axles, thetorque of the motor, by the…
