(a) 59 mm^2

(b) 455 mm^2

(c) 475 mm^2

(d) 3784 mm^2

I got this question at a job interview.

I want to ask this question from Design of Rotor in section Design of Synchronous Machines of Design of Electrical Machines

Answer 1

Right choice is (a) 59 mm^2

Best explanation: Area of each bar = total area / number of bars

Area of each bar = 473/8 = 59 mm^2.
