This gives us the slope up which the car can steadily^run for the giventorque on each motor. — j As a rule, the efhciency -q of the gearing, including the friction and ironlosses of the motor, can be taken as o-8,… … 12 3 PercerUxiqe GracLiefU,. Fig. 204 Strengths of current. The torque exerted by the motor has been taken fromthe table on page 219. A negative value of the slope denotes running down-hill. We have yet to calculate the speed at which the car runs in any givencase. To obtain the revolutions per…
