Answer:
3.115×  meter
 meter
Explanation:
hall-petch constant for copper is given by
        =25 MPa
=25 MPa
       k=0.12 for copper
now according to hall-petch equation 
 =
= +
 +
240=25+
D=3.115×  meter
 meter
so the grain diameter using the hall-petch equation=3.115×   meter
 meter

Answer:
The percentage ductility is 35.5%.
Explanation:
Ductility is the ability of being deform under applied load. Ductility can measure by percentage elongation and percentage reduction in area. Here, percentage reduction in area method is taken to measure the ductility.
Step1
Given:
Diameter of shaft is 10.2 mm.
Final area of the shaft is 52.7 mm².
Calculation:
Step2
Initial area is calculated as follows:


A = 81.713 mm².
Step3
Percentage ductility is calculated as follows:


D = 35.5%.
Thus, the percentage ductility is 35.5%.
