    A three phase induction motor draws a starting current which is five times the full load current with direct on line starting, while developing twice the full load torque. Q2.1. Based on the two facts that starting current is proportional to the applied voltage and that the starting torque is proportional to the square of the applied voltage, determine voltage (as a per cent of rated voltage) required to obtain a starting torque equalling the full load torque.
