Use the elimination method to find a general solution for the given linear system, where differentiation is with respect to t. $(D+1)[u]-(D+1)[v] = e^t$ $(D-1)[u]+(3D + 1)[v] = 8$ Eliminate v and solve the remaining differential equation for u. Choose the correct answer below. OA. The system is degenerate. O B. $u(t)=C_1+C_2e^t+\frac{1}{2}e^t+2t$ OC. $u(t)=C_1e^t+C_2e^{-t}+\frac{1}{2}e^t+2t$ D. $u(t) = C_1+C_2e^{-t}+\frac{1}{2}e^t+2t$ OE. $u(t)=C_1+C_2te^{-t}+\frac{1}{2}e^t+2t$ Now find v(t) so that v(t) and the solution for u(t) found in the previous step are a general solution to the system of differential equations. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. v(t) = OB. The system is degenerate.

Q3 (40 points) A 50-hp, 250-V, 1200 r/min dc shunt motor has the magnetization curve shown in the figure below. If the value of the armature resistor is given as in the table below (each student has his own value of Ra, and the field resistance is Rf ohm (find it from the table). The no-load speed is 1200 r/min. When a compensating winding is used, there are 1200 turns/pole on the shunt field winding, and the demagnetizing magnetomotive force due to armature reaction is 800 A-turns, at a load current of 200A. Find the speed and the torque of this motor when a compensating winding is used and when no compensation is used. The input current is as per the table below. Compare the results and comment on it! load St.No. Rf Ra current 20141412 40 0.04 180 230 20143289 42 0.045 185 233 20161434 44 0.05 190 21706690 46 0.055 195 21712208 48 0.06 200 21800479 50 0.065 205 21802886 52 0.07 210 21807202 54 0.075 215 21807255 56 0.08 220 21809453 58 0.085 225 21812875 60 0.09 230 21814500 62 0.095 235 21815297 64 0.1 240
