Q7. A cylindrical rod of 1040 steel originally 15.2 mm (0.60 in.) in diameter is to be cold worked by drawing; the circular cros
s section will be maintained during deformation. A cold-worked tensile strength in excess of 840 MPa (122,000 psi) and a ductility of at least 12%EL are desired. Furthermore, the final diameter must be 10 mm (0.40 in.). Explain how this may be accomplished. (10 points)

Answer:
6.004 Ω
Explanation:
For a Y- connected system given that :
Line voltage,
Line current ,
and specified that are in phase.
Hence the impedance will be pure resistive.
For Y-system
= phase voltage
= 120.08 V
Line current = Phase current
Now,
= 6.004 Ω
