Electrical Engineering please can you explain with proper steps how the author came up with the answer to this question. i am trying very hard but i cannot seem to get an answer to this question 2. A synchronous generator is delivering 30 % of the maximum power to an infinite bus. If the mechanical input is suddenly increased by 100%, will the synchronism be lost? If not, what is the maximum excursion of ổ about the new steady state? (Ans:58°)

A rotating load is connected to a DC motor with negligible inductance. A test result shows that the load reaches a steady-state speed of 60 rpm (revolutions per second) in 5 seconds when a constant voltage of 12 V is applied to the motor terminals. Let the input be the terminal voltage v(t), and the output be the angular velocity w(t) of the load. (a) Determine the DC gain and the time-constant of the system. (b) Obtain the transfer function of the system.
21. A six-pulse SCR bridge for a three-phase source draws power from a 500 V, 50 Hz line (the volt- age is specified as the RMS line-to-line potential, as is standard in three-phase practice). The rec- tifier supplies a large dc motor. The motor has series inductance La = 0.4 mH and series resis- tance R₁ = 5 ms. The internal voltage Vg = kw, where k is a field flux constant equal to 3 V. s/rad, and w is the shaft speed in rad/s. The shaft torque is Tekia, where ia is the motor current. It is desired to operate this motor with a 250 A current limit to provide a controlled acceleration at start-up. Determine the SCR phase delay angle as a function of motor speed to enforce a 250 A current.
