## (Solved) The electric generator in the steam turbine drive system shown in

The electric generator in the steam turbine drive system shown in the following figure has been running steadily at speed Ohm_10 with a constant input steam torque. T_steam. At time t = r_0, the shaft, which has a developing fatigue crack, breaks suddenly. This problem is concerned with how the speed Ohm_1 varies with time after the shaft breaks (what happens to the generator is of no concern here). Find the steady torque T_0 in the shaft before the shaft breaks. Find the time constant of the remaining part of the system to the left of the crack for t > t_0. Solve for the response and sketch the response. Determine how long it takes (in terms of the system time constant) for reach 5% overspeed than the initial
