Problem 47.- A dc motor develops 55 N-m of torque at a speed of 600 rad/s when12 volts are applied. It stalls out at this voltage with 100 N-m of torque. If the inertiaand damping of the armature are 7 kg-m^2 and 3 N-m-s/rad, respectively, find the transferfunction G(s) = θL(s)/Ea (s) of this motor, if it drives an inertia load of 105 kg-m^2 through a gear train, as shown in the Figure [Section: 2.8] Notice that the following torque-speed...
