7-5. A 50-kW 440-V 50-Hz two-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 520 W, and the core losses are 500 W. Find the following values for full-load conditions:

(a) The shaft speed nm


(b) The output power in watts


(c) The load torque τload in newton-meters


(d) The induced torque τind in newton-meters


(e) The rotor frequency in hertz
