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)

Explanation:
Please kindly check attachment for the step by step solution of the given problem.
Solution :
Given :
k = 0.5 per day
Volume, V
Now, input rate = output rate + KCV ------------- (1)
Input rate
The output rate
= ( 40 + 0.5 ) x C x 1000
Decay rate = KCV
∴
= 1.16 C mg/s
Substituting all values in (1)
C = 4.93 mg/L
