Given: A permanent magnet DC motor with kv = 0.7 v-s is tested under the following two conditions:

Test 1: Apply 120 V; motor unloaded, Ia=2A and w=160 rad/s

Test 2: Apply 120 V, increase load torque until Ia=6A and w=137.1 rad/s

Find the mechanical torque loss and the load torque in test 2. Assume mechanical torque loss is constant (independant of speed).
