1.A shunt-connected DC motor operates at its rated terminal voltage. Its no-load speed is200 radians/second. At its rated torque of 500 Nm, its speed is 180 radian/second. Themotor is used to directly drive a load whose load torque TL depends on its rotational speed(in radians/second), such thatT 2.78 . L T ? ??Neglecting rotational losses, the steady-statespeed (in radian/second) of the motor, when it drives this load is __
