SSC JE Electrical Engineering 24 Jan 2018 Morning Paper

A locomotive exerts a tractive effort of 35,300 N in hauling a train at 48kmph on the level track. If the motor is to haul the same train on a gradient of 1 in 50 and the tractive effort required is 55,180N, determine the power delivered by the locomotive if it is driven by (i) dc series motors (ii) induction motors.
